Line 109:
: An example of a more subtle error is to pick the random point using a polar coordinate system (i.e., using a random distance over the given range and a random angle). The problem is that the distribution of random points is not even w.r.t. area when picked that way; points that are closer in will be more tightly packed. It becomes much more noticeable with a wider annulus. –[[User:Dkf|Donal Fellows]] 15:07, 3 September 2010 (UTC)
:: Using a polar coordinate system isn't by itself an error. Using an uniform distribution for the radial coordinate is, however. --[[User:Ce|Ce]] 16:34, 3 September 2010 (UTC)
