So I was looking for an example of the something like the following for
me to use in class.
I have something I drew in Mathamatica but I ended up using a square for
a circular neighborhood because I don't know how to draw implicit
circles in 3D Mathematica. So I am now trying PSTricks which works for
lots of other cool things.
Show a surface in 3 dimensions (which I can easily do).
Show a small circle or disc at (x1,x2,0) in the x1-x2 plane(which I
Show the points on the surface that lie above this disc (which I am not
sure how to do, I know how to patch it on top of the first surface in
different color, but that is about all)
Put a point on the surface above the disc that is maximal in set (which
I can do).
I would like to add some nice lines and things, but I can do that.
