dear maxima experts---
[1] I am trying to switch from Mathematica to Maxima. I downloaded
and installed it on ubuntu linux 12.04.1 . I can use wxMaxima
successfully. I would like to use the basic command line interface.
I type $ maxima, and then "solve( y + 2 == 0, y)" to the (%i1) prompt
and hit enter...and nothing happens. then I try shift-enter. a ^c
gets me a console interrupt.
[2] I am trying to work with implicit functions. an illustration of
what I want to accomplish is
eqn : solve( y + log(y) + x = 0, y)
plot(eqn, [x,0,1])
I know this is wrong...but how would I do this correctly? (I also
want to use M to ascertain whether dy/dx > 0 .)
help for a poor beginner is appreciated.
