I am creating a maple document to display the tangent plane to a function. the resulting function and tangent plane are displayed in a plot component. The problem I am having is that I can display both the function and the tangent plant at the same time with the foloowing statements:

PlotSurfs := plot3d([Func,TanPln], x = Xo-DmX .. Xo+DmX, y = Yo-DmY .. Yo+DmY,axes=VarAxes,scaling=VarScl,orientation=[OrX,OrY,OrZ]);

 DocumentTools[SetProperty](PlotWin, value, PlotSurfs);
