Before starting, you may want to review the notebooks Derivatives, and Exercises (in the Notebook folder or the back of the Lecture Notes). To make the graphs look smoother you can increasing the number of plotted points with the optional optional argument PlotPoints. For example, Plot3D[ x^2 - y^2, {x,-2,2}, {y,-2,2}, PlotPoints->30] or ContourPlot[ x^2 - y^2, {x,-2,2}, {y,-2,2}, PlotPoints->30] The function Limit[] only finds limits of functions of one variable. In problem 4, you should substitute different expressions for y, then take the limit as x -> 0. For example, z = Sin[x^3y^2]/(x^5 + y^5) z1 = z /. {y -> 2x} Limit[z1, x->0] Be sure to type in comments explaining what you are doing.
