I see it being used repetitively, but have no clue what it means

Shaped like a sine wave, or s-shaped.

Actually, I guess "S shaped" is more appropriate for "sigmoid". Whereas sinusoidal is shaped like a sine wave (as the others above have said).

Anything which is either a*sin(b*x) or a*cos(b*x). In physics, most of the time these will be things related to simple harmonic oscillators - pendulums, springs, etc.
