Graphing an Ellipsoid in 3D https://youtu.be/30yEp-lSwM0 In this video I graph the Ellipsoid quadric surface, whose vertical and horizontal traces are all ellipses. #math #STEM #Geometry #science #GeoGebra
Graphing an Elliptic Paraboloid in 3D https://youtu.be/qIsgOTZSwwY

In this video I graph an elliptic paraboloid in 3D both manually as well as using the GeoGebra 3D graphing calculator. An elliptic paraboloid has vertical traces being parabolas and horizontal traces being ellipses.

Graphing a Hyperboloid of One Sheet in 3D https://youtu.be/a5SxZACKsoM In this video I graph a Hyperboloid of One Sheet, which has horizontal traces being ellipses and vertical traces being hyperbolas. #math #geometry #GeoGebra #STEM #science
Table of Computer Drawn Quadric Surfaces https://youtu.be/IJ0rl3jt_f4

In this video I go over a table of 6 basic quadric surfaces with computer-drawn graphs: ellipsoid, elliptic paraboloid, hyperbolic paraboloid, cone, hyperboloid of one sheet, and a hyperboloid of two sheets.

Modeling Earth as an Ellipsoid https://youtu.be/N2HEZAjE54s In this video I model the Earth as an ellipsoid as used by the World Geodetic System of 1984 (WGS-84) since it is a more accurate model than a sphere. #math #geometry #Earth #science #GeoGebra
A Hyperbolic Paraboloid Can Be Generated by Straight lines https://youtu.be/-nxmXc1GD-U

In this video I show that a hyperbolic paraboloid can be generated entirely by two sets of lines, thus classifying it as a Ruled Surface. The only quadric surfaces that are ruled surfaces are cylinders, cones, and hyperboloids of one sheet.
