Elementary.Acosh1PlusX Method

Returns the inverse hyperbolic cosine of one plus a real number.

Definition

Namespace: Numerics.NET
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3
C#
public static double Acosh1PlusX(
	double x
)

Parameters

x  Double
A real number.

Return Value

Double
The inverse hyperbolic cosine of one plus x.

Remarks

For values close to 0, the hyperbolic cosine is very close to 1. Similar to Log1PlusX(Double), this method uses an alternative formula that gives accurate results for arguments close to 1.
