I have a ti-89 titanium I've used since high school, even if it's overkill I like being able to easily go back through my calculations and pull things back out

>>10429213

Casio has been heavily promoted over at our school. I have a Casio fx-300ES PLUS since its allowed in the contests I join. I would like to have their Classwiz Series tho (the black and white calculator). Our school has those classwiz calculators for borrowers. I like mine so far since it fits well in my bag and its enough for my daily use. Though I owned a Sharp brand before (forgot the model).

What the fuck? Who spends $200 on a calculator for high school?

>>10430060
nothing beats the price of free i guess

>>10429243
The other fatal flaw is much easier to explain. Simply put, it only remembers the answer to the most recent equation. There's no ability to scroll up to previous entries, and if your calculator times out and goes to sleep, it'll clear its memory.
It's something so simple that I've relied on for so long, that I'm not sure I'm willing to give it up.

can do definite integrals and derivatives
can store seven variables
can scroll through previous answers
keeps memory until cleared manually
$20 and under
acceptable on nearly all tests

North American high school math teachers are incapable of teaching students to plot elementary functions without using a calculator to do all the work, so a TI-83, -84, or -89 is usually what schools recommend.

It's all a huge scam, but when your parents never had them and you're a teenager who doesn't know the difference, you buy it anyway and never use it after you graduate high school.

Wow, sounds great.

>>10430132
I love it. I wish the processor was a bit faster though, especially for the equation solver. I also wish you could enter values directly into the vector and matrix functions instead of having to edit the values separately.

>>10430168

Are they in some kind of shady cartel with Texas Instruments?

>>10430104
You can't use phones at exams
You can use programmable calculators with non-qwerty keyboards
CAS is an excellent feature for later studies
Nspire also has a limited mode for exams the teacher can check and switch on, so still allowed.

Anon...

Brainlet here. I have a maths exam coming up (nothing too crazy, not sure where to place it compared to US Calc I/II standards) and I'd feel much more comfortable in it if I could quickly generate graphs.

The calculatpr rules are that it must be a non-programmable "scientific calculator", with additional restrictions in pic related. These are obviously intended to rule out anything resembling a traditional graphing calculator. But I noticed that, strictly speaking, they don't forbid the ability to simply auto-draw a graph (as long as it can't then differentiate/integrate it for me).

Are there any calculators that can render a graph for me but do not offer any calculus features? I couldn't find any with a quick look on Amazon.

>>10430256
It's okay anon, we love you even if you're not smart~!<3

Dead wrong.

>There's no ability to scroll up to previous entries

You just hit the up/down keys. You can change to display to multi-line as well to see them.

Some schools require this.

The same idiots that go with the crowd and buy Ti. "What if the cheaper version doesn't have something I need? I'll just get what everyone is getting to be safe."

Anons were given Casio, but they were, all of them, deceived, for another Calculator was made. In the land of HP, in the fires of Mount CAS, the Dark Company forged in secret a master Calculator, to control all others. And into this Calculator he poured his cruelty, his malice and his Reverse Polish Notation. "HP 50 to rule them all."

>>10430060
So do Casio's.

Casio FX-300ES Plus has a table mode where you can enter 1 or 2 functions and it will evaluate them at a bunch of points. You can then easily plot few points on paper to see a graph or just infer from the table what you were looking for (zeros, maximums, etc).

I'll email them and ask if differentiation/integration refers to just symbolic or if numerical forbidden as well. And ask about baked in scientific constants whether they count or not as retrievable information.

>>10429313
Fuck yeah. I own one of these and its the best thing ever.

>>10430022
HP Prime is better and cheaper

>>10430384
Doesn't that say it can be programmable as long as it doesn't have a full keyboard? I don't see why a standard graphing calculator (with the memory cleared) would be prohibited.

>>10431417
Nice, my parents gave me one for my 19th birthday. Did you get yours new old stock from Faber?

>>10431577
Pretty much every graphing calculator will tell you the slope of a graph. And if they allowed graphing calculators, they would mentioned it.

"Type Z" (programmable) isn't allowed for my exam, only the highlighted "Type Y" (scientific). Also what >>10431604 said

>>10431604
Numerically finding the slope of a graph isn't the same as differentiating it. What kid of "programmable calculator" do you think they're referring to? No one has made fully programmable non-graphing calculators since the 80s.

>Casio V.P.A.M. calculators are scientific calculators made by Casio which use Casio's Visually Perfect Algebraic Method (V.P.A.M.), Natural Display or Natural V.P.A.M. input methods.
>V.P.A.M. is an infix system for entering mathematical expressions, used by Casio in most of its current scientific calculators. In the infix notation the precedence of mathematical operators is taken into account. According to Casio, in V.P.A.M. calculations can be input exactly as they are normally written. Functions, operators and symbols are shown on the calculator display and calculations are performed according to operator precedence.

that is literally both science and math you tard

>>10430384
you're most likely not going to find a calculator dumb enough to not have an algebra solver nor be programmable and be able to plot a graph. most likely the best calculator you can have is the same best one im allowed to use in my calculus class, the ti-30xs multiview
>>10433786
that means it cant have a number solver feature like the ti-36

>In the United States, the TI-89 is allowed by the College Board on all calculator-permitted tests, including the SAT, some SAT Subject Tests, and the AP Calculus, Physics, Chemistry, and Statistics exams.

As far as I'm aware the ti89 titanium is also still produced. It's certainly old tech but not obsolete.

>>10436278
don't (You) me

Also >>10431055 exists being faster, more capable, has more memory, larger hi-res color touch screen, and cheaper to boot

>>10436295
Yeah my calculator has worked for 13 years so far, if the day comes when I need something more capable your calculator will probably be "obsolete", too. Smart phones are more powerful and of course a computer even more so. Doesn't suddenly mean older computational devices are invalidated.

>>10436309
>Doesn't suddenly mean older computational devices are invalidated
Dat cope

>TI-30Xa

We're not allowed to use graphing calculators on tests.

>>10436330
Firstly, are you certain it's invalidated? And second, that is clearly not a handheld calculator.

>>10436309
Obsolete doesn't mean useless. The real problem with TI graphing calculators isn't that the technology is old, it's that the cost is excessive compared to the value of the product.

tips for repairing a graphing calculator? I've got a row of dead buttons after it banged around in my suitcase and have never soldered before

"ITS OK IF YOU SHOW YOUR WORK BRO"

If you weren't born using the abacus then just use the Trachtenberg system for basic calculations, works like a charm even for me who can't build muscle. I could beat easily my teachers at calculations when I was a kid without any real training. They were such a bunch of brainlets

>>10436381
This. If you know your way around any calculator well, stick with it. You'll be way faster than if you have to fumble through endless menus to get to the function you want. At that point, you're better off just plugging it into a search engine. The calculators are simply for convenience and efficiency of input.

>>10436381
Obsolete means no longer produced or used; out of date. Neither of which apply to a calculator that's still both produced, and used.

>>10430132
I had a calculus II professor that insisted that all scientific calculators that allowed you to use the button that would solve a definite integral be discarded for the test

I was kinda hilarious to see all the kids who bought the calculator for the class get cucked while I was lucky enough to use the white and blue version that didn't have that feature
