Mathematica, Plot3D command and 3D points

[Telemachus]

Hi there. Well, I got a surface plotted with Mathematica. I've used the Plot3D command for this. But now I want to plot a point in the same graph. The thing is I've used Taylors polynomial of second degree, and I want to "see" the point around which I'm making the approximation. But I don't know how to plot the point in the same graph, over the surface. I don't know how to plot points in the graph of a surface, using the Plot3D command.

Any help?

Bye there, and thanks.

You want to create a list that has the point or points you want to plot, then use the following command:

Show[Plot3D[...your surface plot...],ListPlot3D[...yourlist...]]

This will show both plots together.
