Hi,
I am starting to learn maxima. The best is to do by examples. So I
have those equations:
eq1:x^2/a^2+y^2/b^2=1;
eq2:A(x-x0)+B(y-y0)=0;
And I want to solve them for A and B. I have the solution in front of
me in the notebook, I just want maxima to do it now, to see how it
works. So in my notebook I do following things:
eq3:(eq1-1)*(a*b*B)^2;
eq4:eq3+eq2;
B_result:solve(eq4,B);
And here I'm stuck. I would expect maxima to calculate
Delta=b^2-4*a*c with respect to B. And show two answers for B.
But it does not.
Having B, I could go forward and calculate A.
I have debian squeeze, and I tried to use to_poly_solve but:
load("to_poly_solve");
Could not find `to_poly_solve' using paths in file_search_maxima,file_search_lisp.
-- an error. To debug this try debugmode(true);
same for to_poly_solver, but topoly loads:
load("topoly");
/usr/share/maxima/5.17.1/share/contrib/topoly.lisp
but still this doesn't work:
to_poly_solve([eq4], [B]);
thanks in advance for your help
