First-Order Linear Differential Equations Definition Example A first-order linear differential equation is a differential equation in the form of where a(t) and b(t) are continuous function on a given interval. A solution for a linear differential equation using chain rule and product rule is as follows: where eA(t) is called an integrating factor. Copyright © 2014, 2010, 2007 Pearson Education, Inc.
