A first order differential equation is called homogeneous if it can be written in the form [math]\frac{dy}{dx}=f\left(\frac{y}{x}\right)[/math]. Its solution requires substitution [math]y=ux[/math], which converts it into a differential equation in u and x with variables separable. The purpose of this applet is to facilitate practice on solving this type of differential equation. A step-wise example is provided. Follow the instructions given in the applet.
