vX: Number whose hyperbolic tangent is returned. Function returns Null if vX is Null or cannot be fixed up to a real or complex number (as defined by the ComplexStringToReals function). Complex numbers are represented within strings as "R|I" where R is the real part and I is the imaginary part.
Return: The result is expressed in radians.
Note: Microsoft named this function HTan within their Derived Math Function help topic.


    Exponent(X) - Exponent(-X)
    Exponent(X) + Exponent(-X)
