prove the identity:
(cosx)(tanx + sinx cotx)=sinx+cos(squared)x
i need steps to show how i got the answer
generally, it is a good idea to change all trig ratios to sines and cosines, and start with the more complicated-looking side.
cosx(sinx/cosx + sinx(cosx/sinx)
just expand and simplify and the RS pops out
