[gradsusr] hyperbolic tangent

[Jean Pierre Arabonis]

Hi all
 I need to get the tanh of an expression, ie something like tanh(htsgwsfc) , this is possible with the standard trig functions eg  tan(htsgwsfc) works but not the hyperbolic ones.
I would appreciate any advice.

    Many thanks
     Jean Pierre
