content: Does anyone outside high school use a graphing calculator? I spent two years as a math major and never touched one, and certainly don't see any use for it now that I'm in engineering. I'm quite happy with my HP 35s!Well, edit: I did "touch" my 50g, but never the graphing functions. I did occasionally find its simplistic CAS useful.

content: Well by looking at this ad, I'd say it's targeted at high school/college aged kids.I don't particularly see anything wrong with using a grapher. I'm a senior in high school and my school gave me a TI-89 for the year. I like the ability to scrollback and stuff. That's pretty handy. As far asneedingone, well no.I'd say, if you have one, use it, unless you're more efficient on something else.My brother gets scorned all the time for bringing his Ti-83 to work by all the gray beards and their RPNs.

content: Quote from: TimNJ on May 09, 2013, 11:14:51 pmOh, there's certainly nothing wrong with it. I've just never found them useful. I've never been confronted with a problem where I though "a graphing calculator would make this easier". Obviously, different people work differently - IloveRPN, for example, but most people find it a huge pain in the ass, and that's OK.What needs to be done is putting some of those "graphing calculator" features (CAS, scrollback, etc) into a nice, compact sci calc. Lord knows powerful microcontrollers are cheap enough today, there's no reason my $50 scientific shouldn't be able to solve the hell out of an ODE or whatever.

HP always design their calculators (and cripple them if need be) to ensure that they meet this criteria. Sales are enough to keep a small handful sized (or less) design division going.

This calculator is not accepted during SAT test.In the USA, most or nearly almost all college bound students take the SAT. A lot of schools use the SAT calculator standard as their own. SAT lists their calculator acceptance criteria on their site which I checked about 6 months ago when my daughter needed a calculator replacement. She stayed with TI since that is what she is familiar with.TI is very smart and get close to that limit without going over.

The big problem is that you have to look closely at the on-screen keypad to make sure your fingers are in the right place. With the "old fangled buttons", you can hit keys without having to look at them, and the tactile feedback keeps your fingers centered.I have fond memories of my old HP-41C (with extra memory too!), but with Wolfram Alpha available on-line for free, there's not much use for a single purpose calculator these days.

content: Quote from: c4757p on May 10, 2013, 01:51:52 amI think computational and mathematical are different skills. I recall around 4 years ago, I saw on the JHU-CTY website application for admission testing page. JHU-CTY is Johns Hopkins University Center for Talented Youth. On the application, they clearly exclude computation skills as acceptance criteria while they focus on math and in appears to particular focus on Spatial Geometry.In case if you have a kid in 4th grade to 12th grade and you don't know about CTY, look into it. It is an international program.The criteria was (4 years ago) you need to be top 5% in standardized test to apply to be tested for admission into the program. Of those applied and given the tested, about 1/2 are accepted. Those in the program are retested at 7th grade and 9th grade.

content: If HP made this calculator with the double molded keys of old, and the carefully researched color schemes of old, and with the keyboard quality, and made a 50G with these things, I would buy it in a heartbeat. I have the 35S. It is close to what I like. I also love my 32SII.When you get accustomed to a calculator like an HP RPN, you can do things so intuitively it makes calculating very second nature. Too bad we are unlikely to see anything like the old HP again. This is not nostalgia, it is because of the logic and care they put into the design.

I will always use the HP49G calculator first if it is handy, but it is nice having exactly the same calculator on my phone. Since the GO49G is an HP Saturn emulator running the HP firmware, the behavior is completely identical to the real calculator.

content: Quote from: jmole on May 10, 2013, 04:39:01 amIf they have gone back to genuine HP calculator keys, and if they have sorted power issues so that you get an excellent battery life, I will be interested. If the new colour display means it can only work for a day before needing charging, I will probably give it a miss. Stick to my passive display calculators. The HP49G does use standard AAA cells that have been around for over 50 years, and will be around for another 50 years. There is something comforting in that. The particular form factor for the battery in the new HP may only be available for the next 10 years or so.I wouldn't mind an E-Ink display HP RPN calculator. With that, they could keep your register stack visible on the screen when the calculator is off, so you could refer back to your last calculations. I haven't used the plotting features much myself, but I have used it a few times to find intersections and zeros. It is good for that.

I rarely (read never) use the graphing features of the 50G. If I want to plot something, just open up Grapher.app and you're a few keystrokes away from any kind of plotting you need to do, even implicit plots. Great for solving for unknowns in EE equations.

content: Quote from: Lightages on May 10, 2013, 02:35:03 amI couldn't agree more.The two things that made HP calculators very attractive were the quality of the keyboard/construction and RPN.Then they suddenly decided to go cheap and the keyboards became rubbish - when I had to replace my 48x I got the then new top-of-the-line (I forget the model number as it sits unused in my desk drawer at home) the keyboard was so bad I sent the first two back before finally trying to live with the third.The 35S has a much better keyboard but it is till not as good as the earlier ones. On my 48x I could press keys without looking at the screen and know that they registered and registered just once. With more recent keyboards you have to check that they have worked.I don't have a smart phone, I don't like typing on glass, having tactile buttons and, for a calculator, enough of them and of a big enough size is important (for me).

With the Andriod and most smart phones, one can easily store a whole text book and cheat-notes. Besides, students have been caught texting questions for answers,photographing exam sheetsfor others or to be sold...SAT may degenerate some in quality, but they are very protective of their asset: their question pool. They will do everything possible to prevent easy photographing of their question pool. So flexible smart devices like the Andriod will likely be excluded for some time to come.

My friend has a TI-36X and is in the same situation. I find it silly not to use the tools you have. I can enter entire expressions and see how values change as I do slight changes. I can essentially create a "sweep" with the Table function. Partial sums with sigma notation, solve matrices and equations. Great for when you are stuck and just don't have time or the chance to review that tiny detail you forgot about something. My calculator is a Casio FX-115ES.Something youcan'tdo is CAS. That means you cannot solve symbolic calculations. That makes this calculator be accepted in certain tests it otherwise wouldn't and gives it its $15 pricetag. I find it actually ridiculous that TI sells this 20 year old, barely updated TI-83 for more than $100 when it clearly costs no more than $30 to manufacture and they had their return of investment a long while ago.

Talk about pinching pennies...I've taken apart many of my calculators. Probably the best one I've seen was from Sharp. They even used a Nichicon capacitor, although it was like 2.2uF and it was soldered to an 0805 pad (should've been an mlcc), but whatever.Really surprised they don't die more often.

This in my opinion in part explains why in the OECD testing we are doing so poorly.

So, I am sure you are smarter than average high school kids.Those just entering high school will be much worst than your generation leaving now leaving high school. The incoming would likely be trained using "every day math", many would not have been taught grammar, and many would not have the skill to even read or write cursive (aka Script).Best of luck to you as you finish up high school and onward to college (or whatever else you have in mind).

TI and HP (and others) are starting to come up with stupid ideas to get people to replace them. Engineers used to design a product specifically to the needs of its users... now, engineers only know how to design a product one way (touch screens, ARM processors, color screens...) and they aren't thinking that perhaps something like battery shelf like might matter for a device that spends most of its time sitting on a desk and not on a charging cradle!Besides, I don't see why there should be ANY difference between the educational market and the professional market... math is math, and students do the same math that professionals do, except they do them for different reasons. I hate how companies are trying to add build in textbooks/examples with their calculators... they're biting off more than they can chew.

content: The graphic calculators were banned at my grammar school (for children 11 to 19 years old). So I bought in 2005 the best non-graphic calculator available! It was an old-looking Casio FX-4800P introduced in 1995 or so. It has 4.5kbytes for storing useful programs or formulas for Maths tests...It's lightweight and it runs on two 3V CR2032 batteries. It has no PC connection. It can solve maths equations numerically.

content: In 2006 Casio introduced an upgraded version named FX-5800P. It has 28kbytes memory, but it's still rather small and lightweight. It runs on one AAA 1,5V cell. The memory is independent on power supply. I love this calculator. I bought it in 2009 and use it at my high school, but not so often. It has a real graphic display, but it cannot draw a graph, so it's not a graphic calculator.I've always wanted to have a Casio ALGEBRA FX 2.0 PLUS or similar, but I found that nobody uses these calculators at high school and the machine is very expensive and heavy! Not suitable for carrying around. My FX-5800P is so light and compact.http://upload.wikimedia.org/wikipedia/en/f/fc/Casio_algebra_fx_2.0_plus.PNG
