comment When integrating, can only one term of an equation be integrated or must entire equation be integrated to maintain equality?
$ydy-xdx=0$ is the same as $\int ydy - \int xdx = 0$ so what do you mean by "what we're really trying to solve"?

Not sure I follow. So you're saying often times the step $y\frac{dy}{dx} - x = 0$ is skipped?

@JohnD write, but the variable being integrated with respect to can be different?

comment Why is it sometimes it seems like you can integrate with respect to x or y and treat the other as a constant, and other times you can't?
ugh not getting it. "In the second case, f is a function of two variables, x and y" I thought the solution of an ODE is always a function of 2 variables: $x$ and $y$

comment Solved ODE, how did answer key rewrite solution to be in this form?
Ugh I didn't know $tan^{-1}1=\frac{\pi}{4}$ for a differential equations course I didn't think I would have to memorize common trigonometric values and my calculator spat out gibberish when I imputed $tan^{-1}1$.
