Re: Solver question  versions  which is the "best"? Message #2 Posted by Bill (Smithville, NJ) on 24 Aug 2007, 2:43 p.m., in response to message #1 by Bruce Bergman
Hi Bruce,
I guess the question is "best" for what  speed, power, correctness, ease of use, etc.
For power and ease of use, I'd have to say the HP200LX. It has a full, if small, keyboard for entering the equations. Multiline screen for editing. Can save/load equations. Easy to transfer to a pc for editing large complicated equation. Full L() and G() implication. Can do graphs. Can be used in a 123 worksheet.
In the calculator realm, I'd have to go with the HP19BII. Multiline display, the full keyboard helps on entering equations.
Second on the calculator side would be the HP17BII. Mainly for the pocket size.
The above is order I would develop a complicated formula  I'd start with the HP200LX or the PC emulator of it. Debug it there. Then type into the HP19BII. Ensure it works there. And, if I need smaller form factor, enter the final debuged complicated equation into the HP17BII.
As far as I know the solver is the same on all three of these. The HP200LX, of course, has some additional features.
I can't comment on any of the newer calculator, since I don't have any of them.
Bill
