In this article, we are going to basically discuss what is the exact differential equation, the standard form,what is the integrating factor, and how to solve exact differential equations in detail with various examples and solved problems. What is Differential Equation? A differential equation is an equation which contains one or more terms which involve the derivatives of one variable i.
A differential equation contains derivatives which can either be partial derivatives or can be ordinary derivatives. The derivatives represent a rate of change, and the differential equation describes a relationship between the quantity that is continuously varying and the speed of change.
There are a lot of differential equation formulas to find the solution of the derivatives. Exact differential equations are not generally linear. In other words, this can be defined as a method for solving the first-order nonlinear differential equations.
The exact differential equation solution can be in the implicit form F x, y which is equal to C. Therefore, this interval actually breaks up into two different possible intervals of validity. This solution is much easier to solve than the previous ones. We do need to worry about division by zero however. We will need to avoid the following point s.
Therefore, we get. This is as far as we can go. Notes Quick Nav Download. Go To Notes Practice and Assignment problems are not yet written. As time permits I am working on them, however I don't have the amount of free time that I used to so it will take a while before anything shows up here.

Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width. Example 1 Solve the following differential equation.
Now, take some partial derivatives of the function. Example 2 Solve the following IVP and find the interval of validity for the solution. Are all separable differential equations exact? What are the applications of ordinary differential equations?
