Hello Maxima users,
I have found something strange (to me) and I don't know if I'm using
Maxima in the right way.
log(x) is not defined in |R for x<0 and the command:
wxplot2d(log(x),[x,-3,3]);
produces an output consistent (according to me);
whereas the commands
wxplot3d(log(x),[x,-3,3],[y,-3,3]);
and
wxcontour_plot(log(x),[x,-3,3],[y,-3,3]);
produce outputs congruent but not consistent.
Where am I wrong either in using or interpreting the Maxima's outputs?
Many thanks in advance for your kind and precious support.
Regards
Claudio
