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

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

    sinh(\frac{1}{x}) = \frac{e^{\frac{1}{x}}-e^{-\frac{1}{x}}}{2}

    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?
