This function calculates the hyperbolic sine of specified complex number.
IMSINH(complex_num)
The complex_num argument is a complex number to return the hyperbolic sine for.
An error is returned if the complex_num argument is not in the form "x+yi" or "x+yj".
Accepts numeric and string data. Returns string data.
IMSINH("6+4i") gives the result -131.848
IMSINH("4+4i") gives the result -17.83
