It seems dx is much larger than 0.000(etc)1.

PS: x is a real number; dx is an infinitesimal part of x.
!= means "not equals"

Umm... No. Actually,
$[Image: gif.latex?\LARGE%20d[f(x)]%20=%20\lim_{h...(x)-f(x-h)]$

That's how we get...
$[Image: gif.latex?\LARGE%20\frac{d[f(x)]}{dx}%20...f(x-h)}{h}]$

dx isn't a number. d is an operator that maps functions to functions. The ratios of these functions produce the derivative.

And for the record...
$[Image: gif.latex?\large%200.\overline{0}1%20=%2...n}%20=%200]$
