Part of me wants to reconstruct all of math up to calculus from scratch and document it all and then create a knowledge map so someone can see how any advanced idea is derrived from the most elementary ideas.
Partly I want to do this for myself just because I have a hard time remembering some derrivations, particularly in calculus where you have to go back to limits to show it.

Its how i was taught too, but i have forgotten so much of the derivation and find it hard to dig up sometimes. Thus id like to document it somewhere in a wiki format.. a wiki of derrivtions and cheat sheets.
