I need help understanding the "principle domain" (a term only my professor seems to use) of a polar function. That is, how do I find the smallest value delta such that [0,delta] plots all of the unique points on the curve; any values greater than delta re-trace points. I suspect that if MeFi could identify the more common name for this, uh, procedure, I'd be set.

I'm looking for some help with a math equation / algorithm I'm trying to create. I'm a programmer by trade and not very good at math so I'd like some help with this or perhaps a site where I could pay someone to come up with the equation I'm looking for. I considered rentacoder or elance however I'd be concerned if the companies there had the proper math knowledge. A lot of claims get made on those sites that turn out to be false. [more inside]
