Question

nis duestion: 1 pt Establish the identity. cos 2 (1 + tan 2 )-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 cos20+ cos 2 Simplify the expression from the previous step by canceling the common factors. cos 0+ The expression from the previous step then simplifies to 1 using what? O A. Quotient Identity OB. Pythagorean Identity O C. Reciprocal Identity O D. Even-Odd Identity E. Cancellation Property Click to select your answer(s). ALIEN

Explanation / Answer

cos2theta(1+tan2theta)

Expanding the product

cos2theta + cos2tehta* tan2theta

Applying the quotient identity

cos2theta + cos2theta(sin2theta/cos2theta)

Simplifying the expression

cos2theta + sin2theta=1 using pythagorean identity
