dx>0 or dx<0 ??
I've just registered in this forum and I wanted to ask my question right away.I'm 18 and I love studying Calculus.While I was studying at Derivative part of it, I've realized something at Leibniz's Notation of Derivative ([itex]\frac{dy}{dx}[/itex]).
It's equal to
lim [itex]\frac{Δy}{Δx}[/itex]=[itex]\frac{dy}{dx}[/itex]
Δx→0
My question is if we take the limit as Δx→0 (Δx→0[itex]^{+}[/itex] and Δx→0[itex]^{-}[/itex])
I think that's why dx must be both dx>0 and dx<0
Is it right??
Thanks..
