Richard,
thank you for the suggestion. Unfortunately, avoiding ratsimp
doesn't help: I have the same behavior with
pT : taylor(p(s),s,0,0);
pbar : integrate(pT,s,-l/2,l/2);
(which works) and
pT : taylor(p(s),s,0,1);
pbar : integrate(pT,s,-l/2,l/2);
(which doesn't). I am using Maxima 5.14.0. Please, let me know if
there is any additional information I could provide.
Best,
Marco
