Functions with no standard pronunciation

There are many mathematical functions with a single widely-agreed written form, but with multiple widely-used spoken forms.

Hyperbolic functions
Common ways of saying \(\sinh\) include "shine", "sine-ch", "sine-aitch", and "hyperbolic sine".

This applies similarly to \(\tanh\), but \(\cosh\) can be read phonetically in English.
