Derivative of cosine theta
WebThe derivative of cos square x is equal to the negative of the trigonometric function sin2x. Mathematically, we can write this formula for the derivative of cos^2x as, d (cos 2 x) / dx = - sin2x (which is equal to -2 sin x cos x). The derivative of a function gives the rate of change of the function with respect to the variable. WebAug 30, 2016 · Another way of "reading" this is to say that when differentiating, first differentiate the outside function while leaving the inside function intact, and then multiply that by the derivative of the inside function. Here, we see that the derivative of the outside function, cos(x), is −sin(x).
