# Separable differential equation

- Separable differential equation
In mathematics, a **separable** differential equation may refer to one of two related things, both of which are differential equations that can be attacked by a method of separation of variables.

* For ordinary differential equations, it describes a class of equations that can be separated into a pair of integrals. See: Examples of differential equations

* For partial differential equations, it describes a class of equations that can be broken down into differential equations in fewer independent variables. See Separable partial differential equation.
