Derivatives of sum, product, and quotient of functions.

WebThere are differentiation laws that allow us to calculate the derivatives of sums and differences of functions. Strangely enough, they're called the Sum Rule and the Difference Rule . So what do the product and difference rules say? The derivative of f ( x) + g ( x) is f ′ ( x) + g ′ ( x). The derivative of f ( x) − g ( x) is f ′ ( x) − g ′ ( x). WebThe Product Rule Since the derivative of a sum or difference of functions is simply the sum or difference of their individual derivatives, you might assume that the derivative of a product of functions is the product of their individual derivatives. This is not true.
