$\frac{d}{dx}\left(4\cos\left(x\right)\right)+\frac{d}{dx}\left(-x\log \left(x\right)\right)$
Learn how to solve problems step by step online. Find the derivative d/dx(4cos(x)-xlog(x)) using the sum rule. The derivative of a sum of two or more functions is the sum of the derivatives of each function. 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=x and g=\log \left(x\right). Simplify the product -(\frac{d}{dx}\left(x\right)\log \left(x\right)+x\frac{d}{dx}\left(\log \left(x\right)\right)).
