WebHow do you calculate derivatives? To calculate derivatives start by identifying the different components (i.e. multipliers and divisors), derive each component separately, carefully set the rule formula, and simplify. If you are dealing with compound functions, use the chain rule. Is there a calculator for derivatives? WebThe derivative of a function describes the function's instantaneous rate of change at a certain point.
