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.

    Wouldn't that just be at `x=pi` where the function is undefined, or is there something more to this question?2012-03-14

    Do you mean: $\cos \frac{x}{x-\pi}$? Under normal notation $x/x-\pi = (\frac{x}{x})-\pi$, which is probably not what you want.2012-03-14

    I formatted your question using LaTeX. Please check to make sure the new version is what you intended to ask.2012-03-14

    There is no need to add a "signature" at the end of your post; the post will include your name at the bottom right automatically.2012-03-14

    @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
