$\frac{d}{dx}\left(2\cos\left(x\right)\right)$
Learn how to solve differential calculus problems step by step online. Find the derivative of 2cos(x). Simplifying. The derivative of a function multiplied by a constant is equal to the constant times the derivative of the function. The derivative of the cosine of a function is equal to minus the sine of the function times the derivative of the function, in other words, if f(x) = \cos(x), then f'(x) = -\sin(x)\cdot D_x(x).
