yes, it would, if you are graphing the position of any point on the spool except the center of the axle.

anything involving a rotating object will produce a sinusoidal function. Even alternating electrical current does, since it is produced by rotating magnets.

If you want to play around with graphing, visit

where you can enter various formulas and can show up to three at a time. Makes it easy to see how tweaking the parameters affects the graph.
