This note contains equations for organic-like motion. Organic equations are useful in animations, for example.

Calm equations:

sin(t)
cos(t)
cost(t)*sin(t)
sin(t)*sin(t*1.5)
sin(tan(cos(t)*1.2))
cos(sin(t*3))*sin(t*0.2)
sin(exp(cos(t*0.8))*2)
cos(sin(t*3)+t*3)
pow( abs(sin(t*2))*0.6, sin(t*2) ) * 0.6

Twitchy equations:

sin(tan(t)*0.05)
sin(pow(8,sin(t)))
sin(t*PI*tan(t)*0.01)
pow(sin(t*PI), 12)
cos(sin(t)*(t*PI)*PI/8)
sin(tan(t)*pow(sin(t),10))
