(D2) limit -------
x -> 0+ 6
Explanation (Richard Fateman):
lhospitallim is set to 5. Yes it is arbitrary, but you
can change it.
Wouldn't it be nicer if there was some
warning message telling us "I stopped, but by
changing this variable you could maybe get me to
evaluate the limit in full"...? This gives the wrong
impression... like "oh! Maxima can't solve that!".
Further comments (Richard Fateman):
I suppose this could be done, but it might also be
the case that after giving up on L'Hopital's rule it
tries something else that might succeed. The
source code for limit is available.
Further comments (James Amundson):
I agree. It also might be a good idea to increase
the default value.
