Sums and Differences of Derivatives - Calculus
www.subjectcoach.com › tutorials › mathThere 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).
