I'm confused as ****. the straight sides of the square should give you a linear graph, shouldn't they? why are they curved like x^3 graphs?
#10 to #4

because they'd have to alter speed im order to keep up with the circle (I'ts less evenly shaped)
#13 to #6

It would be linear if the point tracing the square had a constant linear velocity, but it's the angular velocity, so the graph is actually dy/dtheta  how much the vertical coordinate changes for a change in degrees around the centre of rotation.

Corrections: it's constant angular velocity and the graph is y(theta). The slope of the line is dy/dtheta which is why it's curved rather than constant.
