tan2 csc - tan2 = 0

tan2 (csc - 1) = 0


tan2 = 0

or

csc = 1


Can you solve and answer?

I think so, this problem says it over the interval [0,2pi] do I have to do anything about that?

Yes, the solutions are only within one revolution of the unit circle. tan squared = 0 occurs only twice as does csc = 1.
