How do I find a math function that resembles a heartbeat? I'm guessing it's the sum of a bunch of trigonometric functions

Oh yeah, that's pretty close. I guess if I add another sin or two it will look more jittery and realistic

you meain b(x)sin(x) not b(sin(x)), correct?
thats the first bleep. what about that hump. seems to look like a stand alone sine from 0 tp PI, maybe also some sort of a windowing function.
