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 correct transformations and transform the expression at each step (csc x - cotx)2 (Do not simplify.) Factor out the greatest common factor. Apply a Pythagorean identity inside parentheses. Apply the appropriate even-odd identity inside parentheses. Rewrite in terms of sine and cosine inside parentheses
