    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.

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)
