Our teacher is from Russia so it makes it a bit harder for me to understand him and sometimes for him to understand

our questions....

Currently I have taken Calc 1, 2, 3 and Linear Algebra and understand the topics to an average degree....

diff eq however is giving me wee bits of trouble.

For example I do not know how to tell if an equation is standard form or not?

He gave us the general form for an equation in standard form but I don't "see" how to tell

if an equation is in standard form or not? Some examples he did contradicted my thoughts.

Secondly once you have a linear first order (or I think maybe any order) differential equation in standard form

and it is not seperable (or even if it is) then you can find an integrating factor to make the equation seperable.

I understand the concept, I just for the life of me do not understand what to pick for the different parts that you need

to apply in the formulas for finding said integrating factor?

I will in about two hours post the formulas I have but I think much of my troubles can be helped without them.

Thanks in advance to anyone who can help clear the fog from my problem!
