OT: DIFFERENTIAL EQUATIONS using the HP-48G/GX - Printable Version +- HP Forums (https://archived.hpcalc.org/museumforum) +-- Forum: HP Museum Forums (https://archived.hpcalc.org/museumforum/forum-1.html) +--- Forum: Old HP Forum Archives (https://archived.hpcalc.org/museumforum/forum-2.html) +--- Thread: OT: DIFFERENTIAL EQUATIONS using the HP-48G/GX (/thread-244550.html) OT: DIFFERENTIAL EQUATIONS using the HP-48G/GX - Ivan Rancati - 06-03-2013 I wanted to see how much the book is going for, so I took a quick look on Amazon.com http://www.amazon.com/DIFFERENTIAL-EQUATIONS-using-HP-48G-GX/dp/1886801193/ref=sr_1_fkmr0_1?ie=UTF8&qid=1370269030&sr=8-1-fkmr0&keywords=differential+equations+with+the+hp+48g and it is on sale between 331 and 900 USD. It seems a lot of money. Interesting enough, amazon.de lists a seller who sells it for a reasonable 33 EUR http://www.amazon.de/Differential-Equations-HP-48g-Gx/dp/1886801193/ref=sr_1_fkmr1_1?ie=UTF8&qid=1370269052&sr=8-1-fkmr1&keywords=differential+using+hp+48g No idea why it's so expensive, anyway I thought I'd share in case somebody is interested in the reasonably priced unit Re: OT: DIFFERENTIAL EQUATIONS using the HP-48G/GX - Carey - 06-03-2013 If not mistaken, the contents of this differential equations book as well as a related linear algebra book and a calculus book were all packaged into one large volume entitled HP-48G/GX INVESTIGATIONS in MATHEMATICS by Latorre, Kreider and Proctor, that is usually available at a reasonable price. Re: OT: DIFFERENTIAL EQUATIONS using the HP-48G/GX - Frank Boehm (Germany) - 06-04-2013 It seems like these are just sellers with no physical stock; instead they are auto-listing other stock while adding 500% surcharge :) So hundreds of dollars is most likely not the current market value, it's more or less a random price. If someone buys it: Party time for the seller!
