Hi all, We are developing a productivity tool that has to run on both Leopard and Tiger. We want to support hotkeys for some of the functionalities. Some of the hotkeys are the same as the one registered by the default system. 'Cmd+Shift+3' , 'Cmd+Shift+4' are some of them. We are curren

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

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 -

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.
