the original differential equation (12.1) can be solved by simply constructing a solution to the equivalent exact differential equation (12.5). Example 12.1 ...

Finally the solution to the initial value problem is exy cos2 x − 3 y+ x2 = e21 cos6 − 12. (21) Linear equations. Fortunately there are many important equations that are exact, unfortunately there are many more that are not. • The simplest non-exact equation. y′ = y or equivalently −y dx +dy=0. (22) We easily check ∂M ∂y = −1 0= ∂N ∂x. (23)

1. Consider again a rst order di erential equation P(x;y) + Q(x;y)y0 = 0 (or P(x;y)dx+ Q(x;y)dy= 0) (1) on a simply connected region Rof R2. and assume that it is not exact, i.e. P y 6=Q x on R. Goal To nd a function such that after multiplication of (1) by the equation becomes exact. Such function is called an integrating factor for equation (1).

06.09.2018 · Integrating Factor Definition. A function µ (x, y) is said to be an Integrating Factor (I.F.) of the equation Mdx + Ndy = 0 if it is possible to obtain a function u (x, y) such that µ (Mdx + Ndy) = du. In other words, I.F. is a multiplying factor by which the equation can be made exact. Let us consider the differential equation.
