ok thanks for the reply. my question is, it says make surface and contour plots for suitable intervals, viewpoints, and resolutions. For example f(x,y) = cos(xy) for -3pi <= x,y <= 3pi , that is 1 of the equations for the question. So to make surface and contour plots(many of them) do I just plug other numbers in for -3pi and 3pi? Confused on what I need to do.
