## SurfaceCurveSegmentGetHeading Method (MotionDouble, Int32) |

Get the heading and its derivatives, in radians and radians/meter.

Syntax

public override Motion<double> GetHeading( Motion<double> distanceAlongPath, int order )

- distanceAlongPath
- Type: AGI.FoundationMotionDouble

The distance along the surface path, in meters. - order
- Type: SystemInt32

The requested order indicating the number of derivatives to compute.

The heading and its derivatives, in radians and radians/meter.

Remarks

Note that the units for the derivatives here are in radians and meters.
To get the time rates of change of heading, use the chain rule with the time rate
of change of the arc length parameter.
