Math.Cos Method

.NET Framework 1.1

Returns the cosine of the specified angle.

[Visual Basic]
Public Shared Function Cos( _
   ByVal d As Double _
) As Double
[C#]
public static double Cos(
 double d
);
[C++]
public: static double Cos(
 double d
);
[JScript]
public static function Cos(
   d : double
) : double;

Parameters

d
An angle, measured in radians.

Return Value

The cosine of d.

Remarks

The angle, d, must be in radians. Multiply by π/180 to convert degrees to radians.

Example

[Visual Basic, C#, C++] The following example uses Cos to evaluate certain trigonometric identities for selected angles.
