can someone please remind me, what is the general form for an exponential function with 2 inflexion points and two horizontal asymptotes? if you don't know what I mean, this would look like an S-curve in the third quadrant connected to an S-curve in the first quadrant.
ok nevermind, i got it
Y = (atan(x-Pi) + atan(x+Pi))/Pi (in rad)
