Wanting to find more undocumented features and commands
- Looking through the demos, I see some things that as far as I know are
not documented or hardly mentioned in any of my reading about graphing
calculator. Is there a place where I can find out more secrets?
For example, under Examples/Three Dimensions/Tangent Plane, what do
the ug(a,b) and vh(a,b) do?
Also under Examples/Advanced Topics/Dot Product, you can drag the
endpoints of both vectors around and the complex number is
automaticaly updated. Is there a way to make it so that a point in
the standard x-y plane can be dragged around the graph and the x and y
coordinates would be automatically updated?
Any help would be greatly appreciated. Thanks
