Comment By: Dieter Kaiser (crategus) Date: 20091213 17:50 Message: I am not sure about the notation of infinities which is used in this bug report. Maxima knows inf, minf, and infinity. infinity represents the complex infinity, inf and minf the real infinities.Furthermore, we have minf = inf. With these notations I get: (%i11) limit(x+sqrt(1+x^2),x,inf); (%o11) inf (%i12) limit(x+sqrt(1+x^2),x,inf); (%o12) 0 (%i13) limit(x+sqrt(1+x^2),x,minf); (%o13) 0 (%i14) limit(x+sqrt(1+x^2),x,infinity); (%o14) infinity I think all results from above are correct. Setting this bug report to pending and the status to "works for me".
