I've just begun developing iPhone applications and have found answers to almost all of my questions on stackoverflow via google searches. Now that I'm a little more proficient, I'm trying to give back when I can by sharing tricks I've picked up along the way. Mostly, though, I'm trying to learn what I can from the questions and answers of everyone else.

comment Working out an algorithm for finding out whether a point is in or outside of a 2D closed polygon
@MBennett Good point. It's not necessarily convex. Still, I think many of the ideas that handle the convex case are applicable, so I'll leave this flawed answer up in case it helps. Thanks for the catch.

comment Reverse a mathematics calculation
Do you mind sharing the origin of this problem? It's very ill-posed, so I'm curious as to how it arose.
