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...
