ComplexAtan Method

Returns the inverse tangent (arc tangent) of a Complex, with branch cuts outside the interval [-i,i] along the imaginary axis.

Namespace: Imsl.Math
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0

Syntax

C++

Copy

public static Complex Atan(
	Complex z
)

Public Shared Function Atan ( 
	z As Complex
) As Complex

public:
static Complex Atan(
	Complex z
)

static member Atan : 
        z : Complex -> Complex

Parameters

z: Type: Imsl.MathComplex
A Complex object.

Return Value

Type: Complex
A newly constructed Complex initialized to the inverse (arc) tangent of the argument. Its real part is in the interval $[-\pi/2,\pi/2]$ .

Remarks

The value of Atan is defined in terms of the function Atanh, by $\atan(z) = -i \atanh(iz)$ .
