In calculus, the sum rule in differentiation is a method of finding the derivative of a function that is the sum of two other functions for which derivatives exist. The sum rule in integration follows from it. The rule itself is a direct consequence of differentiation.
The Sum Rule in Differentiation applies to additions of more than two functions. The above Calculator computes a derivative of a given function with respect to a variable x using analytical differentiation.
