You know the sine wave is like having a point on a circle that rotates. It tracks the x-coordinate of the point. Cosine tracks the Y-coordinate. Or is it the other way? I know they are 90-degrees out of phase.
That's why I picked it

Yes exactly, it tracks x and y on the 2D plane. It's the third plane, z, which yields 3D space, that people forget (or have no idea) the sine wave is representing. The movement along z creates the spiral from the circular motion.

I did indeed :¬)
Simply, the sine wave represents a spiral, shown in limited dimensions.
