limit as X--> infinity of cos(x)

1. The problem statement, all variables and given/known data
Find the limit.
$$\stackrel{lim}{x\rightarrow\infty}cos(x)$$

3. The attempt at a solution
As best as I can tell by putting larger and larger numbers in my calculator, there is no limit, as cos(x) just oscillates between (-1,1). So is the limit undefined, or is it 1?

Re: limit as X--> infinity of cos(x)

Your first thought is correct. It is undefined.
