    1. The problem statement, all variables and given/known data
    limit x->infiniti sinx=

    2. Relevant equations

    3. The attempt at a solution

    as x-->infinity values of sinx fall between 1 and -1 meaning that as x approaches infinity, sinx doesn't approach a specific value and so the limit doesn't exist

    I was sorely tempted to say that the limit as "it" approaches infinity must be infinity!

    Of course, you mean the limit as x approaches infinity. As rock.freak667 said, look at what happens to sin(x) as x gets larger and larger- no matter how large x is, sin(x) keeps varying between -1 and 1. It does not "approach" and one number and so there is no limit.
