A) How does 1/2[(1-cosx)/(sinx)+(sinx)/(1-cosx)] equal on of these: secx, cosx, sinx, tanx, cotx, cosx, or 1

B) How does ±√((csc^2x-1)/(csc^2x)) equal on of these: secx, cosx, sinx, tanx, cotx, cosx, or 1

Step 1

Since you have submitted two questions, we'll answer the first question. For the second question please submit the question again and specify it.

We need LCD.

LCD=sinx*(1-cosx)

Multiply first fraction by (1-cosx) and second by sinx in mumerator and denominator.

Then simplify.

Step 2

Add the numerators [since denominators are same]
