Well, then, if you exceed 360 degrees, it's like you're starting over.  Let's say this angle...|dw:1369654775928:dw|

Measures like so.

But as far as Trig (or specifically, trigonometric functions) are concerned, this angle is essentially|dw:1369654869971:dw|


The practical upshot of which, is, if you have an angle, you can keep adding or subtracting 360 degrees to it, it's essentially the same angle :)
