Definition

Let $\Phi$ be a differential equation.

The general solution of $\Phi$ is the set of all functions $\phi$ that satisfy $\Phi$.


Also known as

The general solution of a differential equation $\Phi$ can also be referred to as the solution of $\Phi$, but beware of confusing this with the concept of a solution of $\Phi$.

The general solution of a differential equation can also be referred to as the general solution to a differential equation.


The term solution set is sometimes encountered.

Historical Note

The general solution to a differential equation was formerly known as the complete integral, or complete integral equation.

The Latin term used by Leonhard Paul Euler was æquatio integralis completa.

However, the term integral equation is now used to mean something completely different, and should not be used in this context.
