OT: DIFFERENTIAL EQUATIONS using the HP-48G/GX Message #1 Posted by Ivan Rancati on 3 June 2013, 10:29 a.m. 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 Message #2 Posted by Carey on 3 June 2013, 3:20 p.m., in response to message #1 by Ivan Rancati 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 Message #3 Posted by Frank Boehm (Germany) on 4 June 2013, 4:11 a.m., in response to message #1 by Ivan Rancati 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!
