Class Cos

Namespace

YndigoBlue.Velocity.Functions

Assembly

YndigoBlue.Velocity.dll

Represents the COS (cosine) trigonometric function that calculates the cosine of an angle.

Function

Cos

Implements

ICheckItem

IDefaultItem

IFilterItem

IElement

Remarks

The COS function calculates the cosine of an angle specified in radians. The result is a value between -1 and 1. For angles in degrees, use RADIANS to convert before applying COS. This is useful for geometric calculations, circular motion, and mathematical modeling.

Examples

Calculate the cosine of each angle value in the measurements table:

var schema = manager.LoadSchema("geometry");
var angles = schema["angles"];

var query = new Query()
    .Select([ angles["id"], new Expression("cosine_value", new Cos(angles["radians"])) ])
    .From(angles);

var results = manager.Retrieve(query);

Constructors

Cos(IEnumerable<IElement>)

Initializes a new instance of COS for a composed expression (e.g. COS(col * factor)).

Cos(IElement)

Initializes a new instance of COS for any element.

Cos(Column)

Initializes a new instance of COS for a column.

Cos(Expression)

Initializes a new instance of COS for an expression.
