Write the equation for the height coordinate (z) of an ellipsoid as a function of its width (x) and length (y) coordinates. Use the ellipsoid equation, z = 6*sqrt(1 - (x^2)/1 - (y^2)/2), for this example. Type the right side of this equation into the equation (function) text box of your online graphing calculator. Click the "Plot 3D Graph" function to view the 3-D cross-section of ellipsoid if you are using the livePhysics 3-D calculator listed in the reference section.
Write the equation for the height coordinate (z) of an elliptic paraboloid as a function of its width (x) and length (y) coordinates. Use the elliptic paraboloid equation, z = (x^2)/4 + (y^2)/9, for this example. Type the right side of this equation into the equation (function) text box of your online graphing calculator. Click the "Plot 3D Graph" function to view the 3-D cross-section of the elliptic paraboloid if you are using the livePhysics 3-D calculator listed in the reference section.
Write the equation for the height coordinate (z) of an hyperbolic paraboloid as a function of its width (x) and length (y) coordinates. Use the hyperboloid equation, z = (x^2)/4 - (y^2)/9, for this example. Type the right side of this equation into the equation (function) text box of your online graphing calculator.
