use squeeze theorem to establish limit

lim (as x goes to zero) of x sin(1/x)=0

also help with keying problem? symbosl etc?

For all $\displaystyle x \in \Re $,

$\displaystyle -1 \leq sin(x) \leq 1 $.

This is also valid for $\displaystyle 1/x \in \Re$ $\displaystyle x \neq 0$,

$\displaystyle -1 \leq sin(1/x) \leq 1 $.

Multiply by $\displaystyle x $ and apply the squeeze theorem.
