Public Shared Function Acosh (d As Double) As Double

Parameters

d
Double Double Double Double

A number representing a hyperbolic cosine, where d must be greater than or equal to 1, but less than or equal to PositiveInfinity.

Returns

An angle, θ, measured in radians, such that 0 ≤ θ ≤ ∞.

-or-

NaN if d < 1 or d equals NaN.

Remarks

Multiply the return value by 180/Math.PI to convert from radians to degrees.
