Assembly: Meta.Numerics (in Meta.Numerics.dll) Version: 4.2.0+6d77d64445f7d5d91b12e331399c4362ecb25333
C#
public static double IntegralCi(
	double x
)

Parameters

x  Double
The argument, which must be non-negative.

Return Value

Double
The value of Ci(x).

Remarks

The cosine integral is defined as:

The cosine integral diverges logarithmically to negative infinity at the origin and executes a damped oscillation around zero as its argument increases.

To obtain the non-divergent part of the consine integral near the origin, use IntegralCin(Double).
