How to find this limit

jeudi 1 mai 2014

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



Evaluate: [itex]\displaystyle\lim_{x\rightarrow0}x\sin (\frac{1}{x})[/itex]



2. Relevant equations



[itex]L'H\hat{o}pital's~rule[/itex] (?)



3. The attempt at a solution



Taking the x to denominator as [itex]\displaystyle\lim_{x\rightarrow0}\frac{\sin(\frac{1}{x})}{\frac{1}{x}}[/itex] and Applying L'Hopital's rule I get [tex]\displaystyle\lim_{x\rightarrow0}\cos {\frac{1}{x}}[/tex]

Have I done right? How should I proceed? Thanks.
