Question

What does it mean to have an angle greater than 360 degrees (refering to trig)

Answer 1

A pain in the neck? :)
A full turn is exactly 360 degrees, aye?

Answer 2

Yes all the way round :)

Answer 3

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

Answer 4

Measures like so.

But as far as Trig (or specifically, trigonometric functions) are concerned, this angle is essentially


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 :)
