# Bernoulli differential equation

Template:No footnotes In mathematics, an ordinary differential equation of the form

is called a **Bernoulli equation** when n≠1, 0, which is named after Jacob Bernoulli, who discussed it in 1695 Template:Harv. Bernoulli equations are special because they are nonlinear differential equations with known exact solutions.

## Solution

be a solution of the linear differential equation

Then we have that is a solution of

And for every such differential equation, for all we have as solution for .

## Example

Consider the Bernoulli equation (more specifically Riccati's equation).^{[1]}

We first notice that is a solution. Division by yields

Changing variables gives the equations

which can be solved using the integrating factor

Note that left side is the derivative of . Integrating both sides results in the equations
