I've got some maths homework to do over the summer before I go back to uni and there's this stupid question on there which is one of those 'so basic I don't know it' kind of questions, so here goes.
What is LimΔx→0[itex]\frac{y(x+Δx) - y(x)}{Δx}[/itex] ?
I know that this is just differentiation from first principles, you can take that and derive the whole d/dx relation and stuff, but what exactly is this?
