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: $\displaystyle sinh(\frac{1}{x}) = \frac{e^{\frac{1}{x}}-e^{-\frac{1}{x}}}{2}$
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?
Check it out on Wikipedia.
