    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.

tip: you can get rid of the initial "reference error: X is not defined" error by hijacking one of the globals that you're not using in your dweet: R, T, C, S

This is based on an algorithm from "Electron Graphics and Sound" I read as a kid

We calculate a sine and cosine of a small angle delta initially, and thereafter derive them using trig identities using only addition and multiplication

It so happens that C(O) and S(O) are almost exactly 0.8 and 0.6 for some O

I found those by for(N=0.1;N<1;N+=.1) M=(1-N*N)**.5,console.log(N,M)
