Sin H Function
Math Trig Complex Class

Public Function SinH( _
    ByVal vX As Variant _
    ) As Variant

"Hyperbolic Sine"
Hyperbolic sine of a real or complex number.
Inverse of the ASinH function.

Examples: 
    SinH(-1) = -1.1752011936438
    SinH(-0.5) = -0.521095305493747
    SinH(0) = 0
    SinH(0.5) = 0.521095305493747
    SinH(1) = 1.1752011936438
    SinH(10) = 11013.2328747034
    SinH("2.3|-4.5") = "-1.04069081055929|4.92403489398475"

vX: Number whose hyperbolic sine 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 HSin within their Derived Math Function help topic.
