Verify the identity. 1 + Cos x = (csc x + cotx)2 1 - cos x To verify the identity, start with the more complicated side and transform it to look like the other side. Choose the correct transformations and transform the expression at each step. (csc x + cotx)2 (Do not simplify.) 11 (Simplify your answer.) (Do not factor.) 11 (Factor completely. Do not simplify.) 1 + Cos x 1- COs x
