Graph of paraboloid z=x^2+y^2
Graph of paraboloid z=x^2+y^2-For example, for g(x,y,z) = z−x2−y2 = 0, we have the graph z = x2 y2 of the function f(x,y) = x2 y2 which is a paraboloid Note however that most surfaces of the form g(x,y,z) = c can not be written as graphs The sphere is an example, where we need two graphs to cover itExtended Keyboard Examples Upload Random Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals For math, science, nutrition, history, geography, engineering, mathematics, linguistics, sports, finance, music

The graph of a 3variable equation which can be written in the form F(x,y,z) = 0 or sometimes z = f(x,y) (if you can solve for z) is a surface in 3D One technique for graphing them is to graph crosssections (intersections of the surface with wellchosen planes) and/or traces (intersections of the surface with the coordinate planes)Answer to Find a rectangular equation for the graph represented by the spherical question = 2 cos (a) x^2 y^2 z^2 = 2x (b) x^2 y^2 Note that these parametric surfaces only work for 2 variables, in this case x, y and z are defined in function of phi and theta As far as I am aware, plotting a general 3D equation doesn't work with sympy at the moment Share Improve this answer Follow edited Apr 27 ' at 1047
