 It's been a long-standing tradition in games & demos that sine waves can be approximated by parabolas (see the graph at the bottom). ​ They'​re a little boxier, and deviate to an error of about 6%, but generally work for doing quick and dirty trig. It's been a long-standing tradition in games & demos that sine waves can be approximated by parabolas (see the graph at the bottom). ​ They'​re a little boxier, and deviate to an error of about 6%, but generally work for doing quick and dirty trig.
