$\frac{d}{dx}\left(x-2\left(x-1\right)^{-\frac{1}{2}}\right)$
Learn how to solve sum rule of differentiation problems step by step online. Find the derivative d/dx(x-2(x-1)^(1/2-1)) using the sum rule. Simplifying. The derivative of a sum of two or more functions is the sum of the derivatives of each function. The derivative of the linear function is equal to 1. The derivative of a function multiplied by a constant is equal to the constant times the derivative of the function.
