Step-by-step Solution
Specify the solving method
The derivative of a sum of two or more functions is the sum of the derivatives of each function
Learn how to solve product rule of differentiation problems step by step online.
$\frac{d}{dx}\left(x\cos\left(x\right)\right)+\frac{d}{dx}\left(2\right)$
Learn how to solve product rule of differentiation problems step by step online. Find the derivative using the product rule d/dx(xcos(x)+2). The derivative of a sum of two or more functions is the sum of the derivatives of each function. Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=. The derivative of the constant function (2) is equal to zero. The derivative of the linear function is equal to 1.
