        "sinus hyperbolicus, cosinus hyperbolicus, 
         tangens hyperbolicus, cotangens hyperbolicus"
        SYNTAX: X = sinh(A)
                X = cosh(A)
                X = tanh(A)
                X = coth(A)

        A is an expression whose value is an integer, a rational
        or a floating point number.

        X is assigned the value of the hyperbolic function at A.

        For X = coth(A), A must not be zero.
        

        Example 1: (correct)

                sinh(4.8)


        Example 2: (incorrect)

                coth(0)
