ArcGIS Pro 2.7 API Reference Guide
QueryPolarComponents Method
Example 

ArcGIS.Core.Geometry Namespace > Coordinate3D Structure : QueryPolarComponents Method
Gets the polar components of the Coordinate3D. Angles are in radians.
Syntax
public Tuple<double,double,double> QueryPolarComponents()
Public Function QueryPolarComponents() As Tuple(Of Double,Double,Double)

Return Value

A Tuple containing the azimuth, inclination, and magnitude. Azimuth and inclination are measured in radians.
Remarks

Vector

Example
Coordinate3D polarVector = new Coordinate3D(0, 7, 0);
Tuple<double, double, double> polarComponents = polarVector.QueryPolarComponents();
// polarComponents.Item1 = 0  (azimuth)
// polarComponents.Item2 = 0 (inclination)
// polarComponents.Item3 = 7 (magnitude)

polarVector.SetPolarComponents(Math.PI / 4, Math.PI / 2, 8);
polarComponents = polarVector.QueryComponents();
// polarComponents.Item1 = 0 (x)
// polarComponents.Item2 = 0 (y)
// polarComponents.Item3 = 7 (z)
