Hi,
I've got a question.
When you have 2 variables q1 and q2, is it possible to simplify an
expression like this:
cos(q1)*cos(q2) - sin(q1)*sin(q2)
to obtain the following result : cos(q1+q2) ?
Thanks in advance

It's probably because no one has written it yet. I think it'd be great
to have. We welcome any patches to do that.
You can do the same thing using the apply_map
Hello all
Maxima is much better when drawing 2D plots of functions with jump
discontinuity.
Sage makes a vertical lines at disontinuities, compare
A=plot(1/(x^2-1),(x,-3,3))
show(A,ymax=10,ymin=-10)
in sage and
plot2d(1/(x^2-1),[x,-3,3],[y,-10,10])
in Maxima. Is it possible to remove these
i have trouble in collecting the eigenvectors to form an eigenvector
matrix (in the order given by the eigenvalue computation...).
How can i do this ?

Hi Craig,
I think it is better option (1), but where can I get 3.4.rcl? I don't

In your opinion, which option is better?

This seems to work:
given a symbolic matrix P of dimension 2x2 do:
EVECP = maxima(P).eigenvectors()
EVEC1 = EVECP.part(2)

(second eigenvector)

In integrals variable integration limits work fine with sage.
