RE: graphing equations

[Debian User]

Hi, Doug,

I am also teaching high school algebra.  Like you I have some
students struggling to visualize graphs in three dimensions.  Today I
made an animation using octave gnuplot and the gimp.  Take a look at:

I made each frame of the animation using an octave script you can find
at:

They're far from perfect, but they may help.  You, and anyone else, are
welcome to them.

Good Luck,

Streph
