Question 2

Establish the identity. sec 2 0 ( 1 - sin 2 0) = 1 Rewrite the left side expression by expanding the product. (Do not simplify.) Apply the appropriate quotient identity and/or the appropriate reciprocal identity to the expression in the previous step. sec 20 - () sin 20 Multiply and apply the appropriate quotient identity to the expression from the previous step. sec 20- The expression from the previous step then simplifies to 1 using what? O A. Reciprocal Identity O B. Even-Odd Identity O C. Pythagorean Identity O D. Cancellation Property O E. Quotient Identity
