Verify the identity. sin 2 0 1 - = cos 0 1 + cos 0 . . . 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. sin 2 0 1 - 1 + cos 0 1+ cos 0 (Do not factor.) =1 - 1 + cos 0 = cos 0\fFactor the numerator. Divide out the common factor cos 6. Divide out the common factors cos 0 and 1. Apply a quotient identity. Apply a reciprocal identity and simplify. Apply a Pythagorean identity and simplify. Divide out the common factor and simplify. Apply a quotient identity and simplify. Apply an even-odd identity and simplify
