    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.

Sigmoid activation function used in Artificial Neural Networks. Animation shows changes of neural weights plus a random bias.

u/pavel

I often use sigmoids for movement. The ease-out / ease-in looks great. I used 1/(1+1e9**(.5-t%1)) in d/11146 for the 'jumps'.
