spiral function f[(r)(theta)]

Here's the picture I promised of the spiral and its relation to the circle.

You can see that s=r(theta), relates to f[(r)(theta)]. Theta should be in radians, I'm assuming. But I wasn't prepared to find the equivalents for degrees, so I expressed everything in degrees.

I hope you can see from the diagram, that as the circle forms, the function, f[(r)(theta)] grows.

It appears to be a spiral of Archimedes, with the center axis, perhaps passing through z=4. It's inverted obviously.

EDIT #9:

This is obviously not an Archimedeian Spiral. It's obviously a Logarithmic Spiral. The details should be easy enough to solve.

EDIT: EDIT #2:

(note: principle axises for the spiral are z=4 and y=(7/10)(root 2)(r) - this can be seen in the contuatia 004.jpg)

The values are real, so this, once again, is a real function; not simply something I "cooked up".

Anyone can solve this, if they're interested.

Please ask any questions, if you're interested and there's anything you need to know.

Cheers!
