$\frac{d}{dx}\left(x^2\right)\cos\left(2x\right)+x^2\frac{d}{dx}\left(\cos\left(2x\right)\right)$
Learn how to solve differential calculus problems step by step online. Find the derivative of x^2cos(2x). Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=x^2 and g=\cos\left(2x\right). 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 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). The derivative of the linear function times a constant, is equal to the constant.
