best trig approximations in x86 asm | SCHIZONE EP-31

31st video in a series on scientific computing from scratch using x86-64 assembly. This video compares performance, accuracy, and memory footprint of 9 different sine & cosine approximation algorithms.

Finally its done.

[@grehan900]

Can you explain what he is doing?

[@pinguxor]

​@@grehan900 so there are different algorithms for computing sine and cosine values. He's implementing them in x86 assembly and comparing their performances.
