Hi guys, we went through integrating factors in lecture 3 of this week. When using integrating factor to make a nonexact 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 nonexact 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.
