Hello Katarina:
Are you trying to tell us that "undefined" is what some machine is telling you?

Re: Trigonometry Help!!! =]
I assume that you are trying to solve for x. Try this: sin^2 x = 1 - cos^2 x.
Substitute that in, and get an equation in terms of cos x only.
Then it will be much easier to find x.
