I need help in finding the discontinuity of the function:
$f(x) = \cos \left(\frac{x}{x - \pi}\right)$
Any comments or advice will be much appreciated.
Thanks.

There is no discontinuity check http://www.wolframalpha.com/input/?i=cos%28x%2F%28x-pi%29%29, also it is not defined at $x=\pi$ as the other answer describes.
There is no discontinuity in this function, but there is a point where the function is not defined, namely $x=\pi$, because $\frac{\pi}{\pi-\pi}=\frac{\pi}{0}$ is undefined.
