In any graphics application trigonometric functions are frequently used. But that can be a little expensive in terms of computational time. While it's nice to be accurate, we usually care more about fast if anything. So if we can find an approximation that's "good enough" and is speedier than the real thing, it's generally okay to use it instead.
