Hi all, my maths isn't brilliant but usually if i'm given a substitution, I can figure out a solution fairly easily, for a ordinary differential equation
But I'm very bad at figuring what a useful substitution to make is. Let me give a few examples, along with the substitution suggested in the answers, and can someone explain why that substituion is the logical choice? Thanks alot!
Can't see the logic

I think both these equations are of the form described here
Basically if you have something of the form then substitute .
There are probably other specific types of ODEs which have a specific useful substitution, but I can't remember them if I covered them in my course. We did cover these Bernoulli ones though.
