Comment Comment by eru And it _is_ a random point in a circle. Just not a uniformly distributed one.Btw, here's a way to sample a uniform random point on the edge of a circle without trigonometric functions:Sample x and y coordinates from a standard normal distribution. Then project the result on the circle, by normalising the distance.(You can approximate normal distributions fairly easily. Or your favourite computing environment might have specialised optimized machinery built-in.) parent eru 4 years ago
