    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Visualising numbers for which sin(x)*sin(x) + cos(x)*cos(x) < 1.

u/donbright

wait wait wait wait wait.... sin^2 + cos^2 = 1. im so confused. is this about the imprecision of floating point arithmetic?
u/donbright

this is absolutely fascinating... set it ==1 or >1 gives different patterns.
u/donbright

also fun... return S(n)/C(n)==T(n)
