Re: Two Problems

Thanks for your friendly answers (a rare thing in the newsgroups). I
have still not found an introductory documentation. I.e., a
documentation a student would be willing to read, and explains a bit
more like the basic stuff. Anyway, I will keep on searching following
your tips.

Yes, this is a calculus class for teacher education. I got the burden
to teach an elementary class this year. I was planning to demonstrate
the usage of symbolic algebra too. I am quite used to Maple, but
wanted to try something more affordable. I just stumbled about the
problems above, when trying to compare with Maple.

try tlimitswitch:true
and then limit(x*((1+1/x)^x-%e),x,inf); [not infinity, but
inf].

This one does not work here. I am using wsMaxima, which is based on
Maxima 5.13. I get:

(%i7) tlimitswitch:true;
(%o7) true
(%i8) limit(x*((1+1/x)^x-%e),x,inf);
(%o8) limit(x*%e^(log(1/x+1)*x)-%e*x,x,inf)
