Thread: Finding the integrating factor

This is about exact first order differential equation,
In a case where the given equating is not a exact one, we find the integrating factor.
To find the integrating factor we wither find a function of x, or y.

My question is in a case where we can't find a function of x and y alone, how can we find the integrating factor?

Do you have a specific equation in mind?

Use the integrating factor method when if you don't have that form, you may require another method.

Feel free to post your equation.

Thanks a lot for your help. I managed to solve it, I could make it to be a function of y.

It works if your coefficient of is any nonzero function of as well, you just have to divide the whole equation by that function before finding the integrating factor.
