The Wolfram Language gives you the power to visualize functions of two variables in multiple ways, including three-dimensional parametric plots, spherical plots, polar plots, and contour plots.
Plot the function :
Plot several functions:
Use ParametricPlot3D to plot the surface defined by :
Create a polar plot of a sphere of unit radius:
Use ContourPlot3D to plot a function implicitly defined by :
