06.09.2018 · We observe that the equation is not exact. But if we multiply the equation using (1/x 2) it will become exact. Then we have x d y − y d x x 2 = 0 Which can be put as an exact differential: d ( y x) = 0 ∴ y = c x Is the general solution of equation. Here, (1/x 2) is called an Integrating Factor. Rules for finding integrating factor

it is equally hard as to solve the original equation (1). So, in general, the idea of making equation (1) exact does not give an e cient method to solve it. However, in some speci c cases, this idea works perfectly. (a) For example, suppose we can nd …

which is the same as the one obtained earlier. Thus, the exact differential approach might lead to the solution faster than the other approaches we’ve discussed earlier. Sometimes, the fact that the DE is exact is evident merely be inspection. We list down such exact differentials (verify the truth of these relations): Example – 17

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) • But it can be easily solved! Approach 1: Remember that (ex)′ = ex itself.

The presence of this equality in the linear partial differential equation makes that equation exact. ... This lesson treats finding solutions of ...
