AP Calculus · Axiom Academy

Differentiating quotients of functions When you need to differentiate a quotient (fraction) of two functions, use the Quotient Rule: Pay careful attention to the order in the Quotient Rule: The order matters! "Lo d-Hi minus Hi d-Lo" ensures you get the right answer. Identify u (numerator) and v (denominator): You've mastered the Quotient Rule! Next: The Chain Rule—for composite functions.
