Types of Polar Graphs

Types of Polar Graphs A point P can be located on an X-Y coordinate plane with respect to the origin and can be plotted easily and is written in the form of (x, y). This is known as the rectangular form. But sometimes it is easier to locate the same point or to graph an equation in the polar coordinate form which is the form written with respect to the radius and the angle , written as (r, ). There are different types of polar graphs and they form circles, cardioids, rose curves etc. Example 1: Convert the polar equation, r = 4 to rectangular form and name the shape of its graph. Square the given equation on both sides. This gives: r2= 16 The important conversions from polar form to rectangular form arex = r cos, y = r sin and hence x2 + y2 = r2 Hence we get: x2+ y2= 16. This is the equation of a circle and it is already written in its standard form - x2+ y2= r2. Therefore, the center of the circle is (0, 0) and its radius is 4. Example 2: Convert the polar equation, r = 2cos to rectangular form and name the shape of its graph. Multiply by r on both sides. This gives: r2= 2rcos We know that, x= r cos and x2+ y2 = r2 Hence we get: x2+ y2= 2x== x2 2x+ y2= 0. Using completing the squares method, we get: (x 1)2 + y2 = 1 This is the equation of a circle, written in the form of (x- h)2 + (y- k)2= r2 Therefore, the center of the circle is (1, 0) and its radius is 1.

University of Michigan A Student Interview

University of Michigan A Student Interview The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Brendan received a Bachelors degree in Middle Eastern and North African Studies and a Masters in Modern Middle Eastern and North African Studies from University of Michigan. He is currently a tutor in Chicago specializing in historytutoring, french tutoring, math tutoring, and several other subjects. See what he had to say about his experience at University of Michigan: VT: Describe the campus setting and transportation options. How urban or rural is the campus? Did you feel safe on campus? Are there buses or do you need a car/bike? Brendan: The University of Michigan does have an urban feel, as the city of Ann Arbor grew up around the school. However, that urban feel is not overwhelming. One always feels as if there is something to do, but without the fast-paced environment of a major city. As for transportation, Ann Arbor has an excellent bus system, although many students prefer walking or riding their bikes. However, for those who prefer to drive, it is rather difficult to find a parking space. VT: How available are the professors, academic advisers, and teaching assistants? Brendan:The teaching assistants always make a point of telling students at the start of the semester when their office hours are, as do the professors. It is usually easier, however, to schedule a meeting with teaching assistants than it is with professors, although professors with smaller classes have more time to meet with students. It is also rather difficult to meet with academic advisers, solely because they are assigned so many students. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Brendan:Generally, the dorms on campus were clean and well maintained. The dining halls were also quite nice. Finally, most dorms were located close to the main lecture halls, although the dorms on North Campus were quite far and rather isolated. VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Brendan:All of the major programs were well represented. My undergraduate and graduate majors were Middle Eastern and North African Studies (MENAS) and Modern Middle Eastern and North African Studies (MMENAS), respectively. I chose to study the Middle East because of my long-standing desire to serve our country. As a whole, the University of Michigan did a good job of supporting my area of study. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Brendan:As a freshman, it was quite easy for me to meet people and make friends. I made friends by simply interacting with others in my hall and by joining a running club. However, I knew many people who made the majority, if not all, of their friends through the University of Michigans very prominent Greek system. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Brendan:The Career Center is generally quite helpful. I knew several students who the Career Center found lucrative jobs for. Although there were recruiting events, I did not attend any. As a result, I cannot say which specific companies recruited on campus. VT: How are the various study areas such aslibraries, the student union, and dorm lounges? Are they over-crowded, easily available, spacious? Brendan:The libraries were usually the best places to study on campus. Although I both worked and studied in several libraries, my favorite was the law library. It was very quiet, open late, and the staff was quite friendly. In fact, I was on a first-name basis with the security guard, Filmore, by the time I finished graduate school. The same, however, cannot be said of the dorm lounges or student union. They were crowded and very noisy. Such an atmosphere is not at all conducive to studying. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Brendan:The University of Michigan is the center of Ann Arbor, so to go downtown all one has to do is walk down the street. Even though Ann Arbor is smaller than cities like Detroit or Chicago, there was always quite a lot to do. There were many good restaurants, movie theaters, coffee shops, stores, etc. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Brendan:The student body is very large. There are usually between 30,000 and 40,000 students during the year. During both my undergraduate and graduate careers, I had large and small classes. Although I did not mind the larger classes, I found the smaller ones more engaging. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Brendan:My fondest memory from college occurred during the second semester of my sophomore year. That semester, I had an Anthropology class that focused on the Middle East. For one class session, we were to read a few Bedouin folk stories from Saudi Arabia. One of the stories was known as The Adwani and the Sbayhi. When Professor Andrew Shryock called on me to discuss the story, I was able to recite it in its entirety. Everyone in the room, including Professor Shryock, was impressed. Indeed, later that day Professor Shryock sent me an email in which he referred to me as, Young Bedouin Master.

Heading Back to School- 5 tips for k-12 students

Heading Back to School- 5 tips for k-12 students 0SHARESShare Summer vacations are the happiest days in every student’s life, but there is no vacation that never ends. Here begins the reverse counting for long summer vacation to end and it brings with it the back-to school blues! It’s obvious to feel lazy and stressful while returning to school after a long hiatus, but here are few tactics that may ease your melancholy and will surely benefit in getting back to school with extra zeal. Summertime freedom is extremely opposite to the rigor and strictness of school. Most of the students are not apprehensive to replace their game bags with school bags. Luckily, there are certain preparations that have to be made in order to easily transit from summer vacations to school sternness. Tips for students to make preparations for school after vacations: • Proper sleeping time â€" Students need to make physical preparations while going back to school after summer vacations. They must make schedule for their sleeping time. This schedule should be practiced strictly a week before the vacations end. • Wake up schedule â€" Sleeping on time in night is not worthy if the wake up time is not set for early morning. You’ll miss your school bus if you not get up on time. So, it’s essential to set a wake up time in order to make your body compliant with early mornings. • Correct eating habits â€" No breakfast, junk food at lunch time and dinner out in evenings is quite common for kids as well as parents during summer vacations. But as the school days approach near, these habits should be changed. Proper and healthy breakfast on time, balanced diet at lunch and dinner must be included in your daily schedule. These eating habits would not only make you healthy but also makes your body adaptable for school strict regime. • Learning and study routine â€" This is the most important point that every student must follow with full dedication. Usually, kids do not study during vacations and enjoy the holiday season, but eventually it is the school that is calling them after holidays. So, they must revise their lessons and begin the learning sessions 1-2 weeks before the holidays finish. This will not only make them perfect for upcoming exams, but will also allow them to refresh their minds. • Arrangements for school â€" It is very necessary for all students to keep their books and other things neatly in bag packs in order to avoid last minute rush while going to school. This can be done a day or two before the first day of school after holidays. Also all the projects and worksheets completed during the vacations should be nicely kept. [starbox id=admin]

Huntington Learning Center Offers Tips for Polishing the College Essay This Holiday Break

Huntington Learning Center Offers Tips for Polishing the College Essay This Holiday Break If your senior is preparing application packages for college next fall, holiday break is a great opportunity to put the finishing touches on some of the more personal elementslike the application essay. The college application essay is easily one of the most important pieces your teen will ever write, and Eileen Huntington, Co-founder and CEO of Huntington Learning Center says that students should give it the attention and care it deserves. Essays that are well written and sincere give admissions officers a glimpse into who an applicant is off paper, she says. As teens prepare to send in their applications in the new year,Huntington encourages them to use the downtime of holiday break to polish their application essays. Here are several tips as they do so: Make sure the essay addresses the prompt. The essay is your teens chance to share something about him or herself that isnt addressed elsewhere in the application package. Be sure your teen clearly and thoroughly answers the essay prompt and offers supporting information that shows why your teen is a strong candidate for admission. Evaluate the unique factor. Many students have strong academic backgrounds and impressive resumes, but the essay is your teens chance to shine. The essay must be thoughtful, personal and genuine. It is the appropriate place for your teen to express who he or she really is. Have your teen read any essay draft through the lens of an admissions officer. What stands out? Does the essay poignantly reflect an experience your teen had or does it sound too generic? Edit. By now, hopefully your teen already has a working draft of the application essay and a teacher or guidance counselor has offered comments. The break is a good time for your teen to address any suggestions to strengthen the essay and do his or her own self-edit. After each new draft, encourage your teen to set the essay aside for a day, then review to ensure it is honest, vivid and expressive, and that the topic is meaningful and appropriate and paints your teen as someone capable of succeeding at college. Proofread. Careless errors say a lot to an admissions officer about an applicant. When your teen gets to a final draft that he or she feels good about, its important to print and proofread the entire essay a day or two later. Fresh eyes will help ensure your teen doesnt gloss over words he or she has written and read several times. You can proofread a draft as well, and your teen should consider bringing the final draft to an English teacher as soon as school resumes.

Top 5 Dos and Donts to ACE Your Medical School Interview

Top 5 Dos and Don'ts to ACE Your Medical School Interview MCAT Medical School Admissions This article is a guest post written byAdmissions Helpers. Once an applicant has submitted her application through AMCAS/AACOMAS and completed secondary applications, she can begin to prepare for the next step in the process, the personal interview. There are generally two formats applicants can expect, either the Multiple Mini Interview where an applicant will move from one station to another meeting with different interviewers, and the traditional interview, which can be considered a professional conversation that we will address here. Many applicants make the mistake of trying to anticipate questions and rehearse responses. There is no way to predict exactly what questions will be asked and in fact interviewers are not looking for how much you know, as much as they are looking for an opportunity to learn other things about you to solidify an opinion of how suited you are to successfully pursue a career in medicine. Spending exorbitant amounts of time “studying” for the interview is counterproductive. However, you can take some steps to prepare. 1) Review The first step is to know your own application inside and out. Review all of your activities, education, volunteer work, and research thoroughly on both your primary and secondary application until you know your applications inside and out. Be prepared to articulate your involvement in outside activities and research. For example, if you were in a laboratory studying the genetics of prostate cancer you should be able to articulate the background, hypotheses, methodology, and results in away that shows a strong understanding of your project. Also maintain consistency throughout your application and interview. If your personal statement talks about a single life-changing experience that influenced your decision to pursue medicine, you should refer to that experience in your interview when asked about experiences that led you to medicine. Your rationale for your interest in medicine and the experiences that define you should be consistent. Remember, you were selected based on the information on your application. Your responses pertaining to anything presented on the application should be consistent. Failure to do so can reflect negatively. 2) The interview is NOT a Test Many applicants make the mistake of assuming they are going into a test and that interviewers will be scoring them based on right or wrong answers. Exerting tremendous amounts of energy preparing full answers to questions wastes precious time, energy and creates unnecessary anxiety. What you can expect is that you will engage in a formal conversation with one to three interviewers rather than being tested on your knowledge. Interviewers are interested in your point of view and how coherently you are able to respond. Allowing yourself the freedom to think and formulate answers that articulate your experience and strengths is the most productive way to create a positive impression. Your goal is to sound like someone who can think on their feet rather than to come off sounding rehearsed. The pitfall of spending hours memorizing or rehearsing is to flounder when asked a question that catches you off guard. The contrast in your delivery can have a deleterious effect. So, be prepared but l eave the scripted narrative at home. 3) Brainstorm Key Points This leads to the question, “How do I prepare if not by memorizing answers?” Know that your preparation has been all the hard work you have already done to arrive at the interview. Your goal is to articulate just that. However, you are also encouraged to search online for possible questions. They way to prepare for these anticipated questions is to think about what key points you would hit on in your response, while taking into consideration the information on your application and personal statement. Encapsulate ideas derived from your experience that will produce a compelling response. 4) Become Knowledgeable It is also advisable to go into the interview with some current knowledge of what is going on in healthcare. Healthcare reform, ethical issues including euthanasia, abortion, and stem cell research are challenging topics that may come up during the interview. Current evens are also fair game and may come up on the interview. The New York Times is one credible source to refer to for staying up to date. Having an opinion or ability to comment will contribute to making a positive impression. 5) Dealing with anxiety Feeling anxious is normal! Fighting it will only cause those feelings to escalate. You have worked long and hard for many years. Focus on exercise, meditation or relaxation techniques that will help to ease your anxiety. Your interviewers know you are anxious and are likely to be more forgiving than you might expect. Remember, even if they don’t show it, most applicants are nervous in spite of appearing cool and collected. So, take a deep breath and take it easy on yourself. 6) Pay attention to your non-verbal communication As the old saying goes, “You never get a second chance to make a good first impression,” and non-verbal communication counts! Pay attention that you are appropriately dressed and looking your professional best. You communicate confidence not only by what you say but also through a firm handshake, by looking your interviewer in the eye and maintaining natural eye contact. Finally, don’t forget to smile. hbspt.cta._relativeUrls=true;hbspt.cta.load(215486, '6baac2ae-05a3-4610-9d1f-265c8cbd809f', {});

5 Tips for Landing an On-Campus Job

5 Tips for Landing an On-Campus Job via Pexels.com 1. Consult your college career center. Most likely your college or university has a career center you can visit, where you can obtain information, updates, and guidance about potential career and job options. Starting at the career center is a great first step, especially if you aren’t quite sure how to start in the first place. While most college students probably visit the career center for advice and guidance on future job possibilities, the career counselors there can also be a great resource for those who are looking for an on-campus job. And as career counselors are trained to point you in the right direction, they may also be able to suggest a good on-campus job that lines up with your interests and potential career options. So, if you are at a loss for where to begin, visiting your college career center is certainly a great place to start! 2. Work on making your resume the best it can be. An extremely important part of any hiring process is the resume. In any situation, of course, you want your resume to stand out and show off who you are as a professional individual, which is also relevant to any on-campus jobs you may want to apply to. One great resource to help you improve your resume, as mentioned previously, is the college career center at your school. If you know at least generally what kind of job you will be applying to on-campus, the career counselors there can help you figure out what to emphasize on your resume so that you can display your relevant, previous work experience and academics. Which leads to the next point 3. Capitalize on your academic achievements. When putting together your resume, it’s a good idea to focus on your academic accomplishments. Whether you’re applying for a job as a food server in the dining hall or a paid internship as assistant to the dean, you should do your best to make known your academic achievements (such as honors, awards, and GPA) to show that you are a hardworking and determined individual. Especially if your academic work relates to the job you’re leaning towards, emphasizing your academic achievements will certainly work in your favor. For example, if you are an engineering major, your academic history (such as the classes you’ve taken and the projects you’ve worked on) may be valuable if you want to work on the IT team on-campus fixing things such as computers and screen projectors. 4. Apply to multiple on-campus jobs. Applying to several jobs at once will increase your chances of getting hired for at least one of them. Even if there are some jobs that don’t perfectly line up with your dream career, it certainly doesn’t hurt to apply to several of them maybe some of them work well with your class schedule and would be convenient for you. Whatever the case may be, having at least a few other on-campus job options is ideal so that you have something to fall back on, just in case your first option doesn’t work out. 5. Prepare for your interview. Just like any other job in the real world, it’s definitely always important to prepare for an interview. The type of interview questions will most likely be different depending on what kind of job you’re applying to, but generally you should have some standard answers prepared. That way, no matter what the interviewer asks, you will already have something in your mind that you can quickly use. All in all, landing an on-campus job doesn’t have to be complicated. If you follow the effective and strategic methods outlined here, you may soon be able to find an on-campus job that suits you.

Operation Last Resort Anonymous Takes Up Arms Against the Government

Operation Last Resort Anonymous Takes Up Arms Against the Government Photo courtesy of Matt Cunnelly via Flickr.com Internet “hacktivist” group Anonymous has launched the first out of a series of attacks known as ‘Operation Last Resort,’ a ploy aimed at forcing the government to alleviate what they see as unfair policies. This whole conundrum started as a response to the tragic suicide of Internet guru and RSS innovator Aaron Swartz, a suicide that Anonymous claims Aaron was bullied into committing. They state he was “killed because he was forced into playing a game he could not winâ€" a twisted and distorted perversion of justiceâ€" a game in which the only winning move was not to play.” The initiating factor of the “game” was when Swartz allegedly accessed and downloaded millions of documents from MIT’s JSTOR database, documents of which Swartz was noted to have returned. JSTOR publically announced that they would not pursue Swartz because he swore that the information that he downloaded and returned “was not and would not be used, copied, transferred or distributed. That didn’t deter MIT and the federal government from persecuting Swartz, as they hit him with 13 felony counts and the threat of up to 35 years in prison. Anonymous claims that this intimidating persecution is what ultimately led to the suicide, seeing as Swartz only had one option (He was  being faced with more jail time than your average rapist or killer). And this persecution is exactly why Anonymous is firing back. On Saturday, January 26, 2013, Anonymous infiltrated the servers of the  United States Supreme Court (USSC) website leaving behind a nine minute video, an eloquently written statement, and several files that they referred to simply as “warheads,” named after the court justices. They made their intentions crystal clear: the federal government is to either relinquish what they see as a vice grip on American freedom or be faced with an all out assault. Their statement is as follows: “We have enough fissile material for multiple warheads. Today we are launching the first of these. Operation Last Resort has begun.” Operation Last Resort supposedly means the release of encrypted and sensitive data to several news and media outlets. This initial attack has left the Supreme Court’s severs reeling. On Sunday the USSC briefly regained control of their servers only to be pushed off again. As I currently write this article, the websites of the USSC and Probation Office for the Eastern District of Michigan are fighting heavy loads of traffic and site defamation from a game known as “Asteroids” that Anonymous installed on their servers. The game encourages the harboring of harsh sentiment towards the government by allowing visitors to “symbolically” attack, destroying several components of the websites and pillars of American law (When completed it reveals an image of Guy Fawkes’ famous mask). And Anonymous is far from finished. The government pursued Swartz as a terrorist even after he relinquished files that most agree the public should have access to in the first place. The government also withholds directing any sentiment of wrongdoing on their part to the family and the public, even after JSTOR, whom had its files “stolen,” refused to press charges. Until the government publicly expresses remorse or shows any signs of regret, I don’t expect Anonymous to relent in its protest of what it sees as a vicious and premeditated attempt to subordinate the American public. And as for the game that I referenced in paragraph four,Anonymous’ direct tweet explaining it can be found on the web along with the video.
