A differential equation is an equation that contains derivatives of an unknown function. The solution of the equation is the function that satisfies the differential equation. A differential equation that has one independent variable is called an ordinary differential equation (ODE). A first-order ODE involves the first derivative of the dependent variable with respect to the independent variable. For example, if x is the independent variable and y is the dependent variable, the equation has combinations of the variables x, y, and . A first-order ODE is linear, if it is a linear function of y and (it can be a nonlinear function of x). Examples ...
