Thread: First order ODE

xy' + y - 2x = 0

We need to learn the method where you re-arrange too

N(x,y)dy + M(x,y)dx = 0

Then solve somehow getting d(y-2x)/dy = 1 etc...

Sorry I do not know the name of this method, but I really could do with a step by step sort of guide on how to do it for any example, as I can solve this in many other ways, but don't understand this particular method of solving 1st Order ODE's

Thanks.

I think you're talking about exact equations. See Chris's tutorial, post # 2 (scroll down a little bit).

I think you're right, thanks for the help.

Thanks for trying with the help prove it, I already have the Integrating Factor, Seperation of Variables and also the (y=uv) Method, just needed to learn this one for the course incase it appears on the exam

Thanks anyway tho, brilliant sig btw ! lol
