Some help would be appreciated.

You aren't following the same equations for the circles and the lines. Look at Atero's primer. It has an example of rotating things.

Attached is how to change a sine into a zig-zag line.

a simple way to do that is to use the asin/sin combination, which easily reverses/reflects images:
x=asin(sin(x*pi))/pi; y=...
