 Problems 28 in 9.6 asks you to plot something with a computer. You can use any software for that. If you should want to give Mathematica a try, here is an example on how to plot ```Plot3D[Exp[Cos[x] - Sin[y]],{x,-4,4},{y,-4,4},PlotRange-> All] ``` You can also use the Wolfram Alpha, an online version of Mathematica. Just enter something like ```Plot Exp[ Cos[x] - Sin[y] ] ``` into the search field. You still have the task to figure out how to tweak things so that it looks well.
