Use a graphing calculator to determine which expression can be used to complete the identity below. Then prove the identity algebraically. sin ³x+cos³x sin x + cos x =? Which of the following expressions completes the identity O A. 1-sin x cos x OB. 1+ sin x cos x OC. sin x cos x - 1 3. sin x + cos x sin x + cos x =? To prove the identity algebraically, first factor the numerator of the given expression, = 3 sin x + cos x sin x + cos x sin ³x+cos³x sin x + cos x sin x + cos x (Type your answer in factored form. Do not simplify.) Which identity can be used to simplify the resulting left side of the identity to the correct expression on the right side?
