1. The problem statement, all variables and given/known data evaluate the following limits if it exist lim x sin1/x and limit x sin 1/x x→0 x→∞ 2. Relevant equations 3. The attempt at a solution Someone have told me that I should let t=1/x and rewrite the limits.However, once I rewrite the limit, I still cannot evaluate the limits. So,how can I find the limits?
