[A89] Re: Graphing



This question belongs on the discussion groups at 
http://education.ti.com/global/dg/dg.html

In the future, post questions such as these there. I won't answer another on 
this list.

You can't graph a sphere on a TI-89. The 3D graphing mode only allows you to 
graph only one equation at the same time.  You might try the 3D graphing 
program here, which may allow you to graph more than one 3D equation at once:
