The use of algebraic surfaces in the class room
I have been using some algebraic surfaces in the class room to show the concept of equation, non zero divisors law, simultaneous equations, intersection of conics and many other using the SURFER software of the IMAGINARY.org platform. Guide about the use of algebraic surfaces in the class room Link to PDF But I was Unable to create the same surfaces in GeoGebra and I wanted them in GeoGebra because we all know about the advantages of GGB. I solved the problem. (making one unknown of the surface's equation the subject and using a parametric surface with the surface command.) Complete guide in here: link (It is in Spanish I am working on the translation to English) Surface command with parametric curve: The goal is to create STL files and print most of the surfaces in Herwig Hauser's gallery LINK
