Note the use of the coordcurve option for graphing coordinate curves. The tangent, normal, and binormal options cause those vectors to be drawn. The vectornum commands controls the number of vectors to draw along the coordinate curve. Color is applied to the tangent vectors along the curve via the tangentoptions option.
The PositionVector can be formed interactively via the Context Panel, but at this time there is no simplified access to the PlotPositionVector command. See Table 9.2.4(a) where the About command is applied to verify the properties of the object.
