In mathematics, a separable differential equation may refer to one of two related types of differential equation 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 examples of Separable Partial Differential Equation.
