Hi list!
I'm trying to do this simple limit calculation in Maxima, but I think it
fails:
(C1) limit(atan(x)/(1/exp(1)-exp(-(1+x)^2)),x,inf,plus);
%E %I LOG(- 1)
(D1) --------------
2
/* Since LOG(-1) equals %I*%PI, this should be the same as */
(C2) subst(%I*%PI,log(-1),%th(1));
%E %PI
(D2) - ------
2
/* But doing the calculation step-by-step */
(C3) limit(atan(x),x,inf);
%PI
(D3) ---
2
(C4) limit(-(x+1)^2,x,inf);
(D4) MINF
(C5) limit(exp(-(x+1)^2),x,inf);
(D5) 0
/* shows that the solution should be:
*
* exp(1)*%pi/2
*
*/
What's wrong here?
Thanks,
