Question: Verify the identity. sin 2x+ sin 12x tan (7x) cos2x+ cos 12x Start with the numerator of the left side and apply the appropriate

Verify the identity. sin 2x+ sin 12x tan (7x) cos2x+ cos 12x Start with the numerator of the left side and apply the appropriate formula of sum-to-product sin 2x+ sin 12x (Donot simplify) Now use the sum-to-product formula on the denominator of the left side. (Do not simplify.) cos2x+ cos 12x In the numerator and denominator, substitute the expressions found in previous steps Apply an appropriate identity to simplify the expressions. (Simplify your answer.) The fraction from the previous step then simplifies to tan (7x) using what? Quotient Identity Even-Odd Identity Pythagorean Identity Reciprocal Identity
