A first order linear differential equation can be written in the form
A method to solve this kind of differential equation is to use integrating factor .
The purpose of this applet is to facilitate practice solving these differential equations.
Follow instructions given on the applet. Some of the answers involve absolute values and sgn function because of the piecewise nature of integrand involved. One may use and to compare the user answer without sgn function.
