Step 1
\( \tan \left(\frac{\pi}{2}-x\right)= \) This is a co-function identity. The co-function identity for tangent is cotangent, so the answer is \( \cot(x) \). a. \( \sin (-x)= \) This is an odd-even identity. Sine is an odd function, so the answer is \( -\sin(x) Show more…

Hi, I need help with all these questions please, please do all the work in degrees. Radians are something I did not learn this year and I won't understand it, thanks, they are not covered in my course. For my course all work must be completed in degrees. Thanks :))
