However, this simple method of solution works only because the original differential equation was homogeneous, i.e., the right hand side of the original equation  Every first order differential equation has an integrating factor [math]\rho(x, y)[/ math]. Most first order methods explain how to find this integrating factor. Print. Any equation of the form (1) might be solved using the integrating factor method.

The integrating factor method was introduced by the French mathematician, astronomer, and geophysicist Alexis Claude Clairaut (1713--1765). He was a prominent Newtonian follower whose work helped to establish the validity of the principles and results that Sir Iaac Newton had outlined in the Principia of 1687.

However, this simple method of solution works only because the original differential equation was homogeneous, i.e., the right hand side of the original equation  Every first order differential equation has an integrating factor [math]\rho(x, y)[/ math]. Most first order methods explain how to find this integrating factor.

Such a function μ is called an integrating factor of the original equation and is guaranteed to exist if the given differential equation actually has a solution. The function u is called an integrating factor. This method, due to Euler, is easy to apply. We deduce it by the method of optimism, i.e., we introduce an integrating factor u and hope that it will help us. Proof: We start with the product rule for differentiation d. . (ux) = ux + ux.

where. Some first order differential equations are not separable. Often the most suitable way to solve it is the integrating factor method, which can be used to solve equations of the form Since we only need one integrating factor to solve differential equations in the form $\frac{dy}{dt} + p(t) y = g(t)$, we can more generally note that $\mu (t) = e^{\int p(t) \: dt}$ is an integrating factor of this differential equation.

Introduction. Differential equations can be solved with many different methods. Many of these methods are exclusive to one form of a differential equation.

First Order Linear Differential Equations How do we solve 1st order differential equations? There are two methods which can be used to solve 1st order differential equatio

THE EQUATION: dx dt +p(t)x = q(t). THE INITIAL CONDITION: x(0) = x o. THE INTEGRATING FACTOR: µ(t) = exp Zt p(s)ds . REWRITE DIFFERENTIAL EQUATION: d dt (µ(t)x(t)) = µ(t)q(t). THE INTEGRATION: µ(t)x(t) = C+ Zt 0 µ(s)q(s)ds. THE GENERAL SOLUTION: x(t) = 1 µ(t) C + 1 µ(t) Z t 0 The integrating factor method was introduced by the French mathematician, astronomer, and geophysicist Alexis Claude Clairaut (1713--1765).

General first order linear ODE. We can use an integrating factor $\mu(t)$ to solve any first order linear ODE. Recall that such an ODE is linear in the function and its first derivative.

I The integrating factor method. I Constant coefficients. I The Initial Value Problem. All numerical schemes show a clear fourth order behavior as can be seen from the straight lines in a doubly logarithmic plot with slope a = 4.0 for RK sliders, a = 3.5 for the split step method, a = 3.9 for the integrating factor method, and a = 4.1 for ETD. we cannot use the method of the previous section. However, some inexact differentials yield an exact differential when multiplied by a function known as an integrating factor. If the function g(x, y) is an integrating factor for the differential in Eq.
