Without physics, you can't do mathematics. h has a very real relationship to Planck's constant as a limit between classical (non-quantum) physics and quantum mechanics.. h going to zero results in the classical physics of Maxwell and Newton...

And if you don't understand three dimensions of space and one of time, you live in your own mind, but certainly not mine. (There is more to this subject).

**The relation between x and h in the traditional definition of the derivative is the subject of this thread,** which assumes the definition of the derivative as a limit in an (x,y) global coordinate function space (x,f(x)). If you want to go on about hyper-reals, start a thread on that, but get out of this thread... along with your faith-based concept of mathematics and personal invective.

An alternative definition of the derivative in terms of hyper-reals (if indeed there is one) is not the subject of this thread.
