How to find $x\frac{dy}{dx} = y+\frac{4}{x}$? Its given that $x>1, y=1$ when $x=1$
I dont think I can use separation of variables, for other methods, I don't really understand too well
- What does homologous of degree 0 mean? In my lecture notes, theres some mention of substitution of $z=...$. Resulting in an expression in $z$, which is then separable.
- Integrating factor wasn't explained clearly either, or I just didn't really get it ...
Which method can be used here and how?
