i dont get you amistre64. i need real proof how it came about

amistre64 · Answer

Google is filled with information as to how it came about.  There is only limited space in here to try to teach you what has already been taught so well by others.

If there is anything specific about it that you need help with, that is a doable task tho.

For the record, this is the definition of the derivative.  Your text book should explain it.

The wikipedia article also explains it pretty.

jamesj · Answer

I think the wikipedia article is pretty good.  I'm sorry you don't get it.  This would be a great topic to discuss with your teacher/tutor if you still don't understand.
