limit of a cosine function

Jan Hill

1. The problem statement, all variables and given/known data

limit as t-->10 of cos (1/10-t)

2. Relevant equations

3. The attempt at a solution
Obviously we can't substitute in t = 10 or it would be undefined, so how do we do this. Is there an inequalitly that I haven't considered?
