I do miss the TI-85 interface, which I still know like the back of my hand even after not using it for years - pity TI didn't offer it on the 92/89/Voyage lines. I would be happy with a succesor to the HP-50G that has a more customizeable CAS (auto simplification *flags*, for example, so I could pick if I wan answers in terms of sin/cos/tan, proper fractions,etc) and which is FASTER, FASTER, FASTER. - Marco
From: mdr1024 on 29 Oct 2006 13:55 The quantum leap you are waiting for is a long time coming - Mathematica in a handheld. Aside from cost, I really don't see why it couldn't be done - we have handheld laptop-type computers with sufficient horse power out there. - Marco JT wrote: > That's also what I understand from the official > page at TI's website... the CAS of the NSpire is > not much different from that of the TI - 89 / 92 > calculators. > The rumor was that this was to be a much more > powerful device, with the entire 'Derive' software > package in a handheld device.

How am I supposed to know what time is it in YOUR time jumping around like grazy ;-) -- Veli-Pekka (How would I otherwise know what future calc HP brings out) (than peeking the future) (Unfortunately the future is threaded and thus uncertain or rather propabilistic)

Maple V Release 4 was already ported to a WinCE Handheld around 1998: http://world.casio.com/edu/product/new_products/hpc_edu/ Computer Extender Student version retailed for $400, but I've read that at the end of its life the Cassiopeia sold for $100 with $20 rebate. Maple software cost $100 extra. To use the software, you have to learn Maple V from a 3rd party book or from a PC version of Maple because there's no help file or an extensive manual. One glitch in the CAS for a particular problem is that to find the anti-derivative of sqrt(x)*ln(x), the software will tell you it's too complex for the system to solve. However, it was able to solve x^(1/3)*ln(x). But after entering x^(1/2)*ln(x) and sqrt(x)*ln(x) several times, it eventually solved the original problem. Interface isn't as convenient as a calculator; it's all command line. But you just have to get used to it. There is the ablilty to solve problems using solely the stylus. Too expensive for a student maybe. And with a touchscreen and qwerty keyboard, it's not allowed on school tests. mdr1024(a)gmail.com wrote: > The quantum leap you are waiting for is a long time coming - > Mathematica in a handheld. > > Aside from cost, I really don't see why it couldn't be done - we have > handheld laptop-type computers with sufficient horse power out there. |
