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.

    @AlexBecker It is probably not wise to reformat his question to assume he meant what the normal order of operations meant. It gives false clarity to later people trying to answer the question, when your reformat obscures the likelihood that he mis-entered the question.2012-03-14

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.

    Thats right, the new version is what I intended to as$k$. I $a$m so sorry for the $c$onfusion as I am new to this forum.2012-03-14
