$2\frac{d}{dx}\left(x^2\left(2-2\cos\left(x\right)\right)\right)$
Learn how to solve differential calculus problems step by step online. Find the derivative of (2-2cos(x))2x^2. The derivative of a function multiplied by a constant is equal to the constant times the derivative of the function. Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=. The power rule for differentiation states that if n is a real number and f(x) = x^n, then f'(x) = nx^{n-1}. The derivative of a sum of two or more functions is the sum of the derivatives of each function.
