Hello, all :) I was just wondering a few things: 1) what is the difference between pure mathematics and applied mathematics, and which classes do you need to take in order to get your Ph.D. in either subject? 2) I know this is a really large branch off, but I was wondering how do you start...

Does anybody know where I could find a list of 3-D mechanics of a projectile? I would greatly appreciate it :). Thank you very much in advance :)

what is a moment of inertia? I know it's used for angular mechanics (like angular velocity and stuff like that), but what is a moment of inertia? A good definition with some examples would help tremendously. Thank you much in advance :)

http://www.cosmolearning.com/ This has lectures from multiple sources on multiple subjects not only on mathematics but on quite a few other topics

Where would be the best place to find every trigonometric identity, from sin[2] + cos[2] = 1, to the matrix identities (and Euler's equation would be helpful, also) Also the location of mathematical analysis symbols would be helpful, also. Thank you very much in advance :)
