Complex::Atan Method (Complex)

 

Returns the angle that is the arc tangent of the specified complex number.

Namespace:   System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)

public:
static Complex Atan(
	Complex value
)

Parameters

value
Type: System.Numerics::Complex

A complex number.

Return Value

Type: System.Numerics::Complex

The angle that is the arc tangent of value.

The Atan method for complex numbers corresponds to the Math::Atan method for real numbers.

The Atan method uses the following formula:

ImaginaryOne / new Complex(2.0, 0.0)) * (Log(One - ImaginaryOne * value) - Log(One + ImaginaryOne * value)

The following example illustrates the Atan method. It shows that passing the value returned by the Atan method to the Tan method returns the original Complex value.
