Wrap a sinusoid around the circumference of a circle
I am stuck on finding a way to 'wrap' a sinusoid around the circumference of a circle.
I am performing an investigation where I need to consider the radial surface features of a disk, which would obviously normally be a simple circle (i.e. the radius would be constant). Instead I want to consider the effect of periodic errors in the radius, so that it varies sinusoidally with rotation angle of the disk.
I am unable to come up with a way to create such an object in Geogebra. Can anyone give me an idea how to accomplish this?
I hope this is clear; if not, maybe I can sketch what I mean...
