Why it's here

Cited in discussions of sine implementations and whether lookup tables beat computation on memory-bound hardware.

What it covers

Kaze Emanuar searches for the best sine approximation for the Nintendo 64, comparing the lookup tables in Mario 64 and Ocarina of Time with polynomial alternatives. It walks through numerics and 3rd, 4th and 5th order approximations.
