Recent changes to 895: limit x->inf sin(100/x)*x very slowhttps://sourceforge.net/p/maxima/bugs/895/Recent changes to 895: limit x->inf sin(100/x)*x very slowenMon, 03 Apr 2006 22:44:38 -0000limit x->inf sin(100/x)*x very slowhttps://sourceforge.net/p/maxima/bugs/895/limit\(sin\(a/x\)\*x,x,inf\),a=100 takes about 90 seconds on
a 1Ghz machine, whereas for a=5 it takes 0.1 seconds,
and for unbound a, it takes 0.4 sec.
I am guessing that limit calls trigexpand or some such,
leading to completely unnecessary blowup in the
intermediate results.Stavros MacrakisMon, 03 Apr 2006 22:44:38 -0000https://sourceforge.net9fcf05bccb7d515df36170eeddd6a757fb147bd9
