Integrating factor method

This article introduces the integrating factor technique as a method to solve linear, first-order differential equations. Introduction. Differential equations can be solved with many different methods. Many of these methods are exclusive to one form of a differential equation. To generalize the integrating factor method from linear scalar di erential equations to linear systems of di erential equations. Introduction The integrating factor method is a way to nd solutions to linear scalar equations y0= ay+ b: One multiplies the equation above by the integrating factor (t) = e at; then we get e aty0 ae y= e atb: Integrating Factors and Reduction of Order Math 240 Integrating factors Reduction of order Integrating factors Integrating factors are a technique for solving rst-order linear di erential equations, that is, equations of the form a(x) dy dx +b(x)y = r(x): Assuming a(x) 6= 0 , we can divide by a(x) to put the equation in standard form: dy dx +p Section 4: Integrating factor method 10 A linear ﬁrst order o.d.e.

Since there exist positive integers a and b such that x a y b is an integrating factor, multiplying the differential equation through by this expression must yield an exact equation. We will always use the simplest integrating factor in solving differential equations of this type. Let's now look at some examples of applying the method of integrating factors. Example 1. Find all solutions to the differential equation $\frac{dy}{dt} + \frac{2y}{t} = \frac{\sin t}{t^2}$. This article introduces the integrating factor technique as a method to solve linear, first-order differential equations. Introduction.
