Re: confusing trig problem...That's pi. Phi is normally the "vertical" (not sure exactly what to call it) angle when you are in spherical coordinates. To: First step, as always, is to simplify: Now it becomes fairly simple, just use the trig identity: Where a = x and b = nx Which simplifies to: Last edited by Ricky (20060112 13:08:55) "In the real world, this would be a problem.

Re: confusing trig problem...I have put it on my list to either create or find a website with even the most obscure trig identities. So far, wikipedia (as always) is the best: "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist.
