#2797 asks redundant questions

[dan hayes]

wxMaxima version: 13.4.0
Maxima version: 5.31.1
Maxima build date: 2013-09-24 09:49:12
Host type: i686-pc-mingw32
Lisp implementation type: GNU Common Lisp (GCL)
Lisp implementation version: GCL 2.6.8

(declare(n,integer),assume(n>3,a>0,k>0),integrate(r^(n-1)*exp(-(a-%i*k)*r),r,0,inf))

asks redundant questions is n-1 positive when I just said it was >3

Also it does not solve the integral which has a very easy answer of (n-1)!/(a-%i*k)^n which it does give when replace a-%i*k by just a

[dan hayes]

is that latest version you tested which did not come back with ridiculous questions used in Linux or windows and what version?
Do you know of any issues or bugs worse in the 5.33 than 5.31.1 ?

Redundant questions not observed in current version (post-5.33), therefore closing this report. Maxima still can't compute the integral, but that, while regrettable, is not a bug.
