How do you graph and calculate slope in a 3 dimensional graph?

To plot a 3-d function, say z = f(x,y), you need a 3-d plotting tool.  In general there will be more than one slope at any point, depending on which direction you are interested in.  If you want the slope in the x-direction, for example, you would find the partial derivative of z with respect to x.

Beats me - maybe you should submit an actual question and Alan or someone else might be able to help you. :)

I wondered what the relevance was of partial derivatives - now i have a better idea - thanks Alan.
