Homework Help: Limit as X-> infinity of cos(x)

  1. Feb 26, 2009 #1
    limit as X--> infinity of cos(x)

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


    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.
