Where are the denominators equal to 0?

You run into a problem at x=0, because $\displaystyle \frac{1}{x}$ is undefined there.

Just in case you weren't sure but needed it later:

$\displaystyle sinh(\frac{1}{x}) = \frac{e^{\frac{1}{x}}-e^{-\frac{1}{x}}}{2}$ - Mar 3rd 2009, 02:47 PMronaldo_07
Im not sure what solution the question is asking. Its asking for, its asking to determine the nature. How would I answer that for each part?
