Since multiplying the ODE by the factor $\mu(t)$ allowed us to integrate the equation, we refer to $\mu(t)$ as an integrating factor. 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.

An advice: Do not try to remember the formula itself, that is way too hard. It is easier to remember the process and repeat it. The integrating factor method. Proof: Multiply the diﬀerential equation y0(t)+ ay(t) = b by a non-zero function µ, that is, µ(t) y0 + ay = µ(t) b. Key idea: The non-zero function µ is called an integrating factor iﬀ holds µ y0 + ay = µy 0.

y x) = x d y − y d x x 2 + y 2. d ( arctan. Step 3: Find the integrating factor. We have two cases: 3.1 If the expression is a function of x only. Then an integrating factor is given by ; 3.2 If the expression is a function of y only, then an integrating factor is given by Step 4: Multiply the old equation by u, and, if you … Forms of energy yield differential elements DW i that are not exact differentials, but mathematics postulate that for such elements there exists at least one integrating factor that converts the nonexact differential form to an exact differential; for example, the integrating factor of heat is T −1, yielding entropy as the exact differential dS, dS = T −1 DQ rev. will be an integrating factor.

Ans. The integrating factor is generally used as a multiplying factor to solve complicated inexact differential equations of the first order. Using this integrating factor as a multiplier, the function can be converted to the exact first-order differential equation easily, and by doing that, the equation can be solved very easily and smoothly.
