thank you @Joyobro

You will need specific measurements and check points.

You will also need to understand ALL the components of the general form:

$y(t) = a\sin(b(t-c))+d$

All of a, b, c, and d have significance.  It is very important to note the the argument of the sine funcion is "b(t-c)" and NOT "bt - c"
