Client Evaluations

This calculator is just what I wanted and required. I have owned top of the line graphing calculators from HP, Casio, Sharp, TI, and so on., but overall I like this a single just about the most effective due mainly to its simplicity and ease of use. I like it particularly for trips and outside activities when I can do fairly helpful mathematical explorations that I don't usually have time for at property or in the workplace with my busy schedule. It was designed by HP and teachers, initial and foremost but, as an help in teaching HIGH SCHOOL college students mathematics in a particularly user-friendly manner.
PROS:
1) It is rather simple, pretty light and fairly rapid (75 MHz clock speed), algebraic equation operating technique (EOS), but not with HP RPN, but not poor for the capital since the hp 39gs units are now on sale for $63.99 compared with $59.99 for the new HP 35s for example which is a superb machine, but which is entirely outclassed by this much extra versatile unit. The hp 39 gs is now about one particular year in production getting replaced the 39G+ with a substantially better created keyboard, etc. as described beneath and has evolved by way of 3-4 flavors from the original HP 38 of about a decade ago).
two) Quite well organized analysis activities employing specific Aplets with about a dozen on the market with the unit and a large number of a large number of more on the world wide internet (or you can write your personal considering that programming is also offered on the 39 gs). These specialized Aplets involve analysis of functions, parametric equations, the renowned HP solver technique, statistics, etc. (with least squares curve fits on the market for about a dozen varieties, such as cubic, exponential, power law, logistic or even a user defined kind, etc.!). The unit also has about 200 kb of on the market RAM and about 1 Mb of ROM for the operating system which is a lot additional than the much more strong hp 48gII for example.
3) It will provide three kinds of evaluation for every single dilemma, namely a numerical table of values, a graphic plot (only two-dimensional kinds on the other hand) and a symbolic analysis which is only fully probable for the simplest Calculus cases (polynomials and simple trig, logarithmic and hyperbolic functions). Nevertheless, it also does numerical differential and integral Calculus and it can even supply a Taylor series approximation for your functions. It can also display a fine split-screen view (side by side) supplying a table of values as nicely a plot which is also incredibly beneficial (with a large number of valuable zoom selections).
4) It also handles some advanced mathematical functions (which includes hyperbolics, etc.) and of course can be utilized to analyze complicated numbers, lists and matrices and can even take the square root of negative numbers straight in a pretty straight forward manner (in contrast to the HP 35s)!
five) It also allows the user to make detailed notes and sketches and also interfaces highly nicely with a Computer working with the USB cable supplied with the unit for exchanging info. It also has an RS-232 (serial) as well as an infrared transfer option accessible as properly.
6) It comes with a well written and well organized 314 page users manual and with an even even more advanced manual attainable on the supplied CD.
7) It has a new Flash ROM so that the calculator can be electronically updated if new EOS computer software ROM's are produced by HP without altering out the hardware.
8) Date and time is generally out there with the on-board clock (applying the DISPTIME command)
9) The unit has a entirely redesigned keyboard that has pretty an exceptional feel to it (as opposed to the fiasco's connected with the HP 49g series for example and even improved in my humble opinion than the revered HP 50g now in production for over a year too which I also own). The overall unit appears to be highly properly made and will need to last a particularly long time too. As usually, the calculator special self tests are outstanding and are triggered by basic keystroke commands. Also, Typing Guidelines or AMIGOS in "Property" produces two "HP easter eggs" of men and women who were involved in the design and production of this superb technique.
ten) It has a completely scrollable operations history in Dwelling (unlimited within the available RAM memory and also easy to erase when additional memory is needed) that is extremely easy to manipulate by utilizing the Copy command to recall previously evaluated expressions in order to carry out quick "what-if" evaluation, and so on.
11) It is also incredibly intuitive to operate in my opinion even without having HP RPN. It is a awesome get started to get students and teachers interested in performing even more math and science too which is a quite fantastic factor considering recent trends in North America.
CONS
1) The batteries only final 65 hours according to HP. I can't confirm this fact as of however, but it utilizes 4 AAA batteries as nicely as a typical Lithium battery to be applied as a backup whereas altering the main batteries.
two) It is very thick in comparison to other such calculators and in spite of the supplied high top quality slide-on cover (a maximum total 1.22 inches thick with the cover on for protection), HP ought to have supplied a great case for additional protection as has been its common for several other of its calculators (which includes the HP 35s). Why just imitate the other producers with a slide-on cover for its only protection? HP has at all times gone its personal way in this field thinking about how couple of many people truly recognize or actively use RPN logic every single day (which I have previously constantly preferred for a large number of years now). Most of us now have conveniently accessible computers and compilers to do most computing tasks. I frequently use a calculator at work only to very carefully check intricate pc calculations, but when I do I want it to be rather simple and straightforward to use, specially because I don't use it each day.
3) It will not analyze ordinary differential equations as the alot more advanced calculators can now readily do. Also, the statistical applet correlation coefficient provided is only for a linear curve fit (regardless of the fit assumed). The relative error is supplied rather for both the linear as well as for any of the other curve fit possibilities.
four) Hopefully its sister calculator, the HP 40gs (with a complete HP Laptop or computer Algebra Program-CAS) for UNIVERSITY LEVEL will also be released in North America soon. HP has recently combined efforts (as of early May well, 2007) with a organization in Oregon to use the 39GS and 40GS for routine laboratory measurements at high schools and at universities in the particularly close to future.

I genuinely like my HP 39gs. It really is a wonderful calculator, that I purchased for a affordable price, and it has a definitely beneficial keyboard and screen. HP continues to make fine calculators and I should say that it does its job rather well.
The mastering curve from my old TI-83 SE was a bit steep at to begin with, but as I applied the factor, I got utilized to it and now it really is difficult for me to use any other model of graphing calculator. The OS is beneficial and intuitive, and operating one's way around the keyboard is straightforward sufficient that I don't need any aid with it, not even the manual it came with.
That mentioned, the connection software only functions with Windows, an problem because my main personal computer is a Energy Mac G4, and because my transportable is a PowerBook these days. Not that there's that a lot software out there for HP calculators, as compared to TI models -- there is even additional stuff for my not-permitted-in-most-classrooms TI-89 than there is for my cherished HP 39gs out there on the Net -- but I'd nonetheless like to be in a position to conserve data from the calculator to my Mac with out any difficulty.
So if you own a Pc or don't will need to transfer information from your calculator to your computer system, this is an great get.
