In mathematics, the derivative is a fundamental tool that quantifies the sensitivity of change of a function's output with respect to its input. The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point.
Introduction to Derivatives. It is all about slope! Let us Find a Derivative! To find the derivative of a function y = f (x) we use the slope formula: Slope = Change in Y Change in X = Δy Δx. And (from the diagram) we see that: Now follow these steps: Fill in this slope formula: Δy Δx = f (x+Δx) − f (x) Δx. Simplify it as best we can.
Oct 26, 2024 · Differentiation, in mathematics, process of finding the derivative, or rate of change, of a function. Differentiation can be carried out by purely algebraic manipulations, using three basic derivatives, four rules of operation, and a knowledge of how to manipulate functions.
