I was copying notes in class down, now that class just ended, I was reading over the notes, and I saw this line that went from...
THIS:
[tex]\frac{x-y}{2x} = \frac{dy}{dx}[/tex]
To THIS:
[tex]\frac{1}{2}(1-\frac{y}{x}) = \frac{dy}{dx}[/tex]
But I'm wondering... wouldn't It be this?
[tex]\frac{1}{2}(x-\frac{y}{x}) = \frac{dy}{dx}[/tex]
if not.. how come?
