assuming you are dealing in degrees, the equation will be:

y = 2.1 * sin(360/3.2 * x)

here's what it looks like.



the amplitude is the number of units from the center line of the equation to the highest and lowest points of the equation.

the frequency is equal to 360 divided by the period.

here's a reference
