Public Shared Function Acosh (d As Double) As Double
A number representing a hyperbolic cosine, where
d must be greater than or equal to 1, but less than or equal to PositiveInfinity.
An angle, θ, measured in radians, such that 0 ≤ θ ≤ ∞.
Multiply the return value by 180/Math.PI to convert from radians to degrees.
This method calls into the underlying C runtime, and the exact result or valid input range may differ between different operating systems or architectures.
