Public Shared Function IntegralCi ( 
	x As Double
) As Double

public:
static double IntegralCi(
	double x
)

static member IntegralCi : 
        x : float -> float 

Parameters

x

Type: SystemDouble
The argument, which must be non-negative.

Return Value

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).
