Perhaps I should have added this.....I have upgraded to 5.2 and I realize that there are many additions that 4.2 doesnt have, etc.etc.etc.....that was hardly my point!!!!!.......part of what I was trying to say is that I still use 4.2 just in case and have found it, at least for some of the things I've worked on, to be quite helpful to me in a way that the upgrades were not........naturally, 4.2 doesnt work on every ocassion but I have found many instances where 4.2 will work although 5.2 wont or the answers are completely different......also, in terms of using , for example, a subscripted definition , such as E_subscript_x[x, y, z] , I have also found that 5.2 handles this quite differently then 4.2 especially if you take the derivative of the function.....(the subscript is gotten from the appropriate Palette).....in fact, I can't use this definition in 5.2.... When I sent these comments, I thought that someone, at least at Wolfram, would care and would want to investigate this......if something doesnt work in a New Version but does in an Old Version, strikes me as a Bug in the new software assuming that the earlier Version's answer was, in fact, correct....or, at least, it's food for thought... or I hope it is....Jerry ----- Original Message ----- From: "dimitris" <dimmechan at yahoo.com> To: <mathgroup at smc.vnet.net> Sent: Saturday, February 24, 2007 1:11 AM Subject: [mg73701] [mg73659] Re: Fw: 2 > Try also the following links > > http://documents.wolfram.com/mathematica/Built-inFunctions/NewInVersion5.0/ > http://www.wolfram.com/products/mathematica/newin51/ > http://www.google.com/search?hl=en&q=mathematica+version+5.2 > > May be this material will convince for upgrading! > > Regards > Dimitris > > =CF/=C7 fizzy =DD=E3=F1=E1=F8=E5: >> This is an interesting question for me for another reason.....my >> 'favorit= > e' >> version of Mathematica is still 4.2....I have found many things that >> work= > in >> 4.2 but do not work in 5.2....I have always been meaning to send them to >> mathgroup but, must admit, I'm too lazy for it.....however, this example >> here is perfect for the ocassion.... >> >> It works in 4.2......interesting also, that the Output in 5.2 for the >> Series[ ] question, the answer seems different....I havent investigated >> it >> further, just want to point out the interesting differences..... >> >> Jerry Blimbaum >> >> ----- Original Message ----- >> From: "Andrzej Kozlowski" <akoz at mimuw.edu.pl> >> To: <mathgroup at smc.vnet.net> >> Sent: Thursday, February 22, 2007 3:35 AM >> Subject: >> >> >> > Try: >> > >> > Series[ArcCosh[x], {x, 0, 11}] >> > >> > and now try >> > >> > ArcCosh[x] + O[x]^12 >> > >> > At least with my version of Mathematica: >> > >> > $Version >> > 5.2 for Mac OS X (February 24, 2006) >> > >> > >> > I do not get the same answer (in fact in the latter case the input is >> > returned unevaluated).
