Question: Verify the identity. 2 cost = cos t cot t sin t Which of the following four statements establishes the identity? A. cos t 1

Verify the identity. 2 cost = cos t cot t sin t Which of the following four statements establishes the identity? A. cos t 1 = cos t(cos t) = cos tcot t sin t sin t B. cost 1 = cos t(sin t) = cos t cot t sin t COS C. 2 cos t 1 = cos t(sin t) = cos tcot t sin t sin t OD. 2 COS t 1 = cos t(cos t) = cos t cot t sin t cos t
