    cos x (assuming x is measured in radians).

    Your other post is asking for the derivative of cot x, which begs the question: If you don't know what the derivative of sin x is why are you attempting to answer questions asking for the derivative of cot x?

    I guess we won't know for sure what was wanted unless the OP provides clarification .....
