question: public static LatLon rhumbEndPosition ( LatLon p , double rhumbAzimuthRadians , double pathLengthRadians ) { if ( p == null ) { throw new IllegalArgumentException ( "LatLon Is Null" ) ; } return rhumbEndPosition ( p , Angle . fromRadians ( rhumbAzimuthRadians ) , Angle . fromRadians ( pathLengthRadians ) ) ; }
target:  Computes the location on a rhumb line with the given starting location, rhumb azimuth, and arc distance along the line.
