Is it possible to plot equations like: x^2+y^2/4+z^2/9=1 ?
I know that it can be done if each half is expressed as a function or if it is written in parametric equations, but I was wondering if it is possible to plot any quadratic surface directly. Thank you. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
