Is this a valid approach to finding critical values of a trig function

[QUOTE="verty, post: 4790999, member: 54975"] At this step: 2=csc^2 (t/2), I see two ways to proceed. 1) Use the identity for csc^2, remember that it is very similar to the sec^2 formula: csc^2 = 1 + cot^2. This gives 1 = cot^2(t/2). OR 2) Take reciprocals. This gives 1/2 = sin^2(t/2). Then if you are careful to include the minus sign when taking square roots, you should get 4 candidate values for t/2.
