Define
ss(a,N):=(print([a,N,i]),sum(i^a,i,0,N));
Now do
plot2d(ss(.5,i),[i,0,5]);
Maxima repeatedly asks the sign of i, and control-G cannot escape from
this. I do understand that when N is a non-integer, the sum will
return a noun form. But that should be OK.
Two problems:
1) It asking the sign of i?
2) I escape from this infinite loop using control-G?
Thoughts?
