$\frac{d}{dx}\left(\frac{1}{x+1}\right)+\frac{d}{dx}\left(x^{-1}\right)+\frac{d}{dx}\left(\ln\left(x+1\right)\right)+\frac{d}{dx}\left(-x^{-2}\right)$
Learn how to solve sum rule of differentiation problems step by step online. Find the derivative d/dx(1/(x+1)+x^(-1)ln(x+1)-x^(-2)) using the sum rule. 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 (-1) is equal to zero. Any expression multiplied by 0 is equal to 0.
