Question 771932: Use fundamental identities to simplify the expression below and then determine which of the following is NOT equivalent.
+sec+theta+%28+sin+theta+%2F+tan+theta+%29+
I worked as best I could and came out with +%28+1+%2F+costheta+%29+%28+sintheta+%2F+%28+sintheta+%2F+costheta+%29+%29++
Additionally, I have no idea what "which of the following is NOT equivalent" is referring to -- there is no multiple choice or further info than what I've posted. Any help regarding this would be greatly appreciated.

You can put this solution on YOUR website!
+sec+theta+%28+sin+theta+%2F+tan+theta+%29+
= sec*sin/(sin/cos)
= (1/cos)*sin/(sin/cos)
= 1
