You can't just find the derivative of cos(x) and multiply it by the derivative of sin(x) ... you must use the Product Rule as explained on the Derivative Rules page. It actually works out to be cos2(x) - sin2(x). So that is your next step: learn how to use the rules.ou can't just find the derivative of cos(x) and multiply it by the derivative of sin(x) ... you must use the Product Rule as explained on the Derivative Rules page.
