    Check if the left hand limit = right hand limit. If it is, then limit exists. Existence of limit at point a implies the function is continuous at point a.

    Check if\[\lim_{x\rightarrow 2^+}f(x)=\lim_{x\rightarrow 2^-}f(x)\]

    \[f(x)=\sin \frac{ 1 }{ x-1 }\]Use limits to determine if is continuous at x =1
