1. Find the real part of z=ii by using De Moivre's formula. Homework Equations z= r(cos\theta + i sin\theta) zn= rn(cos(n\theta) + i sin(n\theta)) I tried using n=i to solve and got the ans 1i, but somehow feel that its not that simple. And the resultant argument I got from this...

I'm on pace to take Differential Equations and Signals & Systems I (EE course) simultaneously in the 4th semester; the course catalog says that it is highly recommended that I take Diff. Eq. prior to Signals & Systems I. So, if I switch Diff. Eq. with a literature course (which I can take...

Hello everyone, I was wondering if Canadian graduate schools care about whether you have taken a year or two with a full-course load. By full-course load, I mean the maximum 10 courses per year compared to just doing 8 or 9 courses. I know that some Canadian medical schools require you to...

I.e. If you have two or more completely different textbooks for a college calculus course or any mathematics course , then will some of the books omit important things, and other books will probably cover more things, How can you be sure your getting a good education with math and science if...

Let's say I receive a grade that I'm not satisfied with, like a C+ or B-. If I choose to take the course again, then would my first grade still be present on my transcript. What if I get a lower grade, would that grade "stick"? Is this a feasible way to raise my GPA?

The difficulty of the courses is one of my major priorities in my selection of the universities I intend to apply to soon. I don't want any easy "plug-and-chug" crap as I would be bored easily and lose motivation to study. So I am asking you guys, which university has in your opinion the most...

Hi, all. I'm currently in a graduate program in philosophy and simultaneously doing work in mathematics. Since I've not experienced advanced math until now, I have no way to judge how realistic my projected course loads will be. Any input would be useful. A little about my situation. I'm...

I'm finishing up a masters degree (non-thesis) in AE, and am faced with something of a dilemma.

The title of this thread speaks for itself, but to contextualize it, I should say that I am currently in the third (final ) year of my physics course and I have to choose some classes. Accordingly to the choices I have decided so far I would not do an Optics class in my course. Is that...

Yet another "which math course to take?" thread Dear PF members, First, I would like to apologize in advance for asking this type of question repeatedly. I just haven't made my mind yet, and I just think getting another advice from PF members might be helpful. So, I'm going to be a...

I am trying to decide between two different graduate math classes in the fall. These are the only classes that sound really interesting to me, as well as fitting in with the rest of my schedule. My other courses will consist of several physics type courses, notably, Jackson's electrodynamics...

Hello everyone. I'm planning on taking some mathematics courses this fall, with the intent to return to school for an engineering degree as "full time" as I am able this spring. I live in the Boston area, and noticed that Harvard extension school has some good calculus/linear algebra courses...

It's been a long time since I've had to do this stuff so bare with me! Compute and graph the following: (a) -15+i/4+2i (multiply by the conjugate and I got -2.9+1.7i (b) (271/3)4 Now for some reason I have a feeling this has 3 solutions using complex numbers but can not figure them out...

Hi. I have done some algebra (mostly group theory and linear algebra), and single-variable real analysis at the level of baby Rudin. Currently I have a choice between two courses: Analysis: Lebesgue and Fourier analysis; Hilbert and Sobolev spaces; fractals and approximation theory...

Hey all, I'm starting my first year of university in a month or so, taking the specialist program (equivalent to honors program at my university) for pure mathematics. I am also going to take applied mathematics and physics courses, out of interest (hopefully I take enough physics courses to get...

What is a short book which covers all of the key results in calculus in a rigorous manner?

I believe there are a number of errors in my physics correspondence course and I plan to include a page listing them when I write my final exam, but I would first like to make sure they are errors and not due to my lack of understanding. 1) "The coulomb is defined as the amount of charge...

I was wondering what you should be familiar with before taking Calculus II. I just finished the Calc I summer class and was wondering if I should go on to Calc II this summer or just go over Calc I some more... I mean I can solve all of the problems that were presented but we hardly had any...

There is a scientific word/explanation for the phenomenon that a out and back course in a cycling time trial race can actually be faster than a flat course. For example, in Cherokee Park in Louisville, there is a 10 kilometer course that starts on the flats, then has a pretty good downgrade...

I plan on studying math through real analysis. I am taking calc 3, and linear algebra at the moment. Calc 3 is not a problem for me, but linear algebra is by far the most difficult class I've had in my entire life. I'm still hoping I can get a B, but I may have blown that with the test I took...

Hi, I am pursuing graduate studies in economics, and I hear that "measure theory" is one of the classes that will impress admission commitees. I don't see anything by that name in my school's catalog. Does this class go by another name sometimes?
