they should do that automatically

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
    \cosh ax \qquad \cosh(ax)
\]
\end{document}

in the case of the \cosh(ax) no space is needed as the ()'s already 
provide the separation.

Note that function names such as cosh should be written in an upright 
font, not as $cosh ax$ as that can be interpreted as $c \cdot o \cdot s 
  \cdot h \cdot a \cdot x$

amsmath defines a lot of these function name shortcut such as \cosh, 
other can be defined uding

\DeclareMathOperator{\macroname}{Text}

Manual spaces can be inserted via \:,\, etc. But one should be a bit 
careful and think whether this is actually a good thing to do.
