[LUGSB] texmacs and maxima

Sun Aug 10 09:54:44 EDT 2003

Replying to myself.. I found what I was doing wrong. I was not giving the LHS 
constants for the equations.. i.e. I was not giving A,B,C and hence the 
problem! This sequense solved the problem:

 (C1) d*exp(-a*r^2);
(D1)
(C2) A = D1;
(D2)
 (C3) diff(D1,r);
(D3)
(C4) B = D3;
(D4)
 (C5) diff(D3,r);
(D5)
(C6) C = D5;
(D6)

then solve([D2,D4,D6],[a,d,r]);

That solved it! So maple does do what maxima does!

This was sent to the club's email address: lugsb at ic.sunysb.edu and I
thought that you guys might find it amusing.  Enjoy.
