    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.

change f(x) and d (difference)

u/katkip

f=x=>S(x/9)+C(x/9);d=81 is nice

lol that is actually equivalent to f=x=>S(x/9)*2;d=81
