Differential Equation

Explore DifferentialEquation on MathWorld

A differential equation is an equation that involves the derivatives of a function as well as the function itself.

Differential equation is a college-level concept that would be first encountered in a differential equations course. It is an Advanced Placement Calculus AB topic.


Ordinary Differential Equation: An equality involving a function and its derivatives.
Partial Differential Equation: A partial differential equation is an equation involving a function and its partial derivatives.


Derivative: A derivative is the infinitesimal rate of change in a function with respect to one of its parameters.
