Use the following equation to create a symbolic function Z:
Z=sin (√X^2+Y^2)/√X^2+Y^2
a. Use the ezmesh plotting function to create a three-dimensional plot of Z.
b. Use the ezsurf plotting function to create a three-dimensional plot of Z.
c. Use ezcountour to create a contour map of Z.
d. Generate a combination surface and contour plot of Z, using ezsurfc.
Use subplots to put all the graphs you create into the same graph.
