## What is nonlinear partial differential equations of first order?

First-Order Nonlinear Partial Differential Equations. C2 = f(C1), ΦC1 + ΦC2f′(C1) = 0, where f(C1) is an arbitrary function, the prime stands for the derivative, and ΦC1 and ΦC2 are partial derivatives.

## Which is non-linear partial differential equation?

In mathematics and physics, a nonlinear partial differential equation is a partial differential equation with nonlinear terms.

**What is the example of nonlinear differential equation?**

Nonlinear Equation + 2x + 1 = 0, 3x + 4y = 5, this is the example of nonlinear equations, because equation 1 has the highest degree of 2 and the second equation has variables x and y.
