I'll do that, thanks for the push in the right direction. “You know the world is going crazy when the best rapper is a white guy, the best golfer is a black guy, the tallest guy in the NBA is Chinese, the Swiss hold the America’s Cup, France is accusing the U.S. of arrogance, Germany doesn

Ah, thank you for that. This will allow me to scrap much of my HTML generation code. The images spat out seem to be quite small, which is a real bonus. I need to use CGShading, because a lot of people will be running this on 10.4 (I assume they won't be able to use the other way)? Uns

Re: [Math] sin(), cos() not working? What special magic must I use to summon their powers?

I think there is more than one problem here. You may want to get a good book about the C language (Obj-C is just a superset of C). Variables i, cornerSize are passed to the function from a for loop. i being the counter for the loop, cornerSize being the size of corner desired by the user.

Re: [Math] sin(), cos() not working? What special magic must I use to summon their powers?

I'm guessing cornerSize is an int? so i/cornerSize will always return 0, so asin(i/cornerSize) will always return 0 so cos(asin(i/cornerSize)) will always return 1 so (1- cos(asin(i/cornerSize))) will always return 0 you want to do i/(float) cornerSize -
