  1. Solve 1 - sin^2x + sin x = 1
    That can be rewritten, after subtracting the 1's from both sides, as:
    sinx (sinx +1) = 0
    sinx = 0 or -1

    What angles would those be? Hint: One of them is x=0.

    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

    ( tanx/1-cotx )+ (cotx/1-tanx)= (1+secxcscx) Good one! Generally these are done by changing everything to sines and cosines, unless you see some obvious identities. Also generally, it is best to start with the more complicated
