Add the following functions by inserting them at the appropriate lexicographic place in 6.8:

6.8.x IMSINH
Summary: Returns the hyperbolic sine of a complex number
Syntax: IMSINH( Complex N )
Returns: Complex
Constraints: None
Semantics: If N=a+bi, then sinh(N)=sinh(a)cos(b)+cosh(a)sin(b)i.

and

6.8.y IMCOSH
Summary: Returns the hyperbolic cosine of a complex number
Syntax: IMCOSH( Complex N )
Returns: Complex
Constraints: None
Semantics: If N=a+bi, then cosh(N)=cosh(a)cos(b)+sinh(a)sin(b)i.

Also insert both functions in the function listing in 2.2.4.
