Title: Question on Week3 Lec3 Integrating Factor
Post by: RunboZhang on September 25, 2020, 04:27:01 PM
Hi guys, we went through integrating factors in lecture 3 of this week. When using integrating factor to make a non-exact equation exact, we have different types of it. Namely, we have mu(x,y)=mu(x), mu(x,y)=mu(y), and mu(x,y)=mu(xy). I am particularly confused by them. When we are solving a non-exact equation, shall we try three different types and see which one would be helpful, or is there a way to give an instant intuition?

I could be wrong, but I think we just try each one until we get one that works :)

Indeed.
