Verify the given sum-to-product formula. Start with the right side and obtain the expression on the left side by using an appropriate product-to-sum formula. a -B a +B sin 2 sin a - sin ß = 2 cos 2 What product-to-sum formula can be used rewrite the right side of the equation? cos e sin o = (cos (0 - 4) + cos (0 + p)] Rewrite the right side of the equation using an appropriate product-to-sum formula. a - a + B sin 2 = 2 2 cos 2 (Do not simplify.) The expression determined the previous step then simplifies to sin a - sinß using what? Select all that apply. O A. Cancellation Property O B. Even-Odd Identity O c. Quotient Identity
