What is a good level of math required for, like, advanced core animation? Take this for example:

And what's a good book/resource to learn it?

Hi Guys,
I'm constructing a geolocation based application and I'm trying to figure out a way to make my application realise when a user is facing the direction of the given location (a particular long / lat co-ord). I've got the math figured, I just have the triangle to construct.
//UPDATE
So…

so I'm trying to make a program that will output the sum, average, and smallest and largest values. I have everything basically figured out except the smallest and largest values are outputting 2147483647 and -2147483647, which I believe are the absolute smallest and largest values that Java will…

I've heard many times that all programming is really a subset of math. Some suggest that OO, at its roots, is mathematically based. I don't get the connection. Aside from some obvious examples:
using induction to prove a recursive algorithm
formal correctness proofs
functional languages
lambda calculus
asymptotic…

I have a continuous stream of news items and stock details that I turn into CALayers…

I'm new to iPhone development, and doing some experimentation with Core Animation. I've run into a small problem regarding the duration of the animation I'm attempting.
Basically, Ive got a view with two subviews, and I'm trying to animate their opacity so that one fades in while the other fades…

I have a simple App that displays a list of items using NSTableView. There are usually about 15-25 items in the list, and the table has 10 columns, all but one of which are text (the other's an icon.) There are simple data transformers on a couple of the columns. So nothing taxing; you'd expect it…

Can anyone here recommend any good books for getting my head around Core animation?
I've been through the Apple docs and while I'm sure it's all there, I haven't been able to grok Core Animation yet... Is there an a good example I've missed? or some starting document I've overlooked?
If not are there…
