asinhadvanced// Inverse hyperbolic sine (works for all reals)
Math.asinh(0) // β 0
Math.asinh(1) // β 0.8813...Use Math.asinh() to compute the inverse hyperbolic sine of any real number.
As x approaches infinity, Math.asinh(x) also approaches infinity.
Challenge: Verify that Math.asinh(Infinity) returns Infinity.
