Hey all, I was wondering if someone can walk me through this one:
[cot^2(B) - cos^2(B)]/[csc^2(B) -1]
My solution is as follows:
[cot^2(B)/-sec^2(B)] - cos^2(B)/-sec^2(B)
and now i am a bit stuck. the correct answer is cos^2(B). Can someone please finish this off or tell me a better way to get to the right answer?
