public static double ChebyshevT(
	int n,
	double x
)

Public Shared Function ChebyshevT ( _
	n As Integer, _
	x As Double _
) As Double

public:
static double ChebyshevT(
	int n, 
	double x
)

static member ChebyshevT : 
        n:int * 
        x:float -> float

Parameters

x (Double): The argument, which must lie in the closed interval between -1 and +1.

Return Value

The value of T_n(x).

Remarks

Chebyshev polynomials are orthogonal on the interval [-1,1] with the weight (1-x²)^1/2.
