I want to show a function which includes the tanh of a fraction, i.e.
\tanh(\frac{x - g}{h})
but which gives me the normal small parentheses. I already tried \tanh\(\frac{x - g}{h}\) but this just omits the parentheses at all. So how can I get large parentheses which enclose the entire fraction?

There is a way. But the result is simply terrible:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$B\!\left(\tfrac{n+1}
{\ooalign{%
$\scriptstyle\hphantom{n+1}$\cr
\hidewidth$\scriptstyle2$\hidewidth}%
\smash{\rlap{,}}}\,2\right)$
\end{document}
Here's how I'd typeset the whole thing, in descending order of preference:
$B((n+1)/2,2)$
$B\bigl((n+1)/2,2\bigr)$
$B(\tfrac{n+1}{2},2)$
You probably want
$\mathbf{E} = E_0 \bigl[\frac{1}{\sqrt{2}} \mathbf{\hat{x}} \cos(kz-\omega t)
+ \frac{i}{\sqrt{2}} \mathbf{\hat{y}} \cos(kz-\omega t+\frac{\pi}{2})\bigr]$
For getting a variable in boldface the correct way is to say \mathbf (which works also with accents such as \hat).
Instead of \bigl[ and \bigr] you can say \left[ and \right], it depends on personal taste: I feel that the latter gives too high brackets.
For the "cosine function" the right input is \cos.
