I am just starting Calculus II, and I have thrown everything I know at this thing, to no avail

$\displaystyle \lim_{x \to \infty} (x sin\frac{\Pi}{x})$

Also, is there a guide for [,math] [/.math]? I swear the amount of time it took me to figure it out... you're damn lucky I am going into Computer Science! =P

Any assistance is greatly appreciated.
