Hi,
I'm learning differential equations, and although I understand the methods I have learned thus far, I often have trouble seeing what is the reasoning behind them.
Take for example, the use of the integrating factor when solving first order linear ODE's. I understand how to use it, but I'm not sure where it came from. In the resources that I'm using there's really not explanation, instead the discussion is limited to: assume there's a function by which we can multiply our differential equation to make it integrable.
Can anybody explain why we use this approach?
thanks,
Erik
