The derivative of cos(2x) is -2sin(2x). The process of finding this derivative uses the chain rule. We can use integrals to check our work when finding derivatives. If D(x) is the derivative of f(x), then the integral of D(x) is f(x) + C, where C is a constant.

Explanation: We use the quotient formula here. It states if f (x) = h(x)g(x) Let's set a equation \begin {equation} \frac {\sin x} {2+\cos x} = \frac {\sin (x+p)} {2+\cos (x+p)}. \end {equation} It can be manipulated as \begin {equation} 2\sin x +\sin x \cos (x+p) = 2\sin (x+p)+\cos x Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. Now we know we can use the chain rule to find the derivative of cos (2 x) by plugging it into our formula. The only other information we need is as follows: The derivative of cos (x) is -sin (x).

This is one of the best and most empowering books I have ever read: https://amzn.to/3bps8bY 2020-09-25 · There are two methods that can be used for calculating the derivative of cos^2x. The first method is by using the product rule for derivatives (since cos 2 (x) can be written as cos (x).cos (x)). The second method is by using the chain rule for differentiation. Finding the derivative of cos^2x using the product rule First of all y = cos2x = (cosx)2.
