I learned to program on those TI-84 calculators in the mid 00s. I wrote a snake game and distributed it to my high school classmates, and ended up becoming the popular kid for a while because of it.

I have a ti nspire cx cas. The thing is overprized but the solve function and desolve are great. They are really lenient with formatting compared to something like Geogebra.

>>60373024
I can give an example of just how lenient the thing is.
I once tried using the solve function to solve the area under two different curves and what I did was I entered the integrals into the solve function and set the high and low of the integral as the value in which integral 1 - integral 2 was equal to zero, and the calculator gave me an answer.

I have a Ti-89 and it's basically the most powerful thing I can have without my professors getting suspicious.
Something with a keyboard would be great but it would draw a lot of attention. Especially since I already put some equations and notes into my 89.
Other calculators including the Ti-84 just can't compete because I need to be able to solve for imaginary numbers and integrate. My 89 passed Calculus and Diff Eq for me. Really helps in classes like Fluid Mechanics and Dynamics as well.

>>60373312
>>60377086
Schools here in the US often use ONLY Ti84s in the classroom and that's just because it makes it easier for teachers. They only need to know how to use one calculator and that's all they can teach their students. Even with a Ti-89 in highschool, enough was different that I needed to Google how to do things while the rest of the class could just follow the teacher with their 84s.

You forgot Camels.

TI bought their way deep into school systems and made it the defacto norm to have a TI calculator to the point of it being required since they can only validate so much. If they can tell at a glance that you're using an approved calculator it makes things much easier on anyone handling an exam.

So TI was able to price their calculators fairly high and still have people buy them because they had to, much like textbooks. Then as time passed and they became cheaper and cheaper to make, the price stayed the same because why lower it when you have literally no competition and everyone HAS to have your product?.

Not to mention once you hit the second semester of year 10 basically everything you learn in maths is how to use the calculator to solve problems for you.

Physics

>Says my hands are like a baby's and that I should be a hand model.

>What a Gaylord
>The entire subject is just plugging things into kinetics equations with prime suspect number one the TI-84 calculator

Typically was homeschooling in America your parent is the one that's teaching you they know you better than any of the teachers at school are going to know you or be able to teach to you, usually of the new rank a lot higher than public school kids outside of the ones I would excel no matter what so long as their given material. The only real disadvantage to homeschooling would be a lot of the kids come out of it socially and not because they've never had to deal with people that are shitty for that long. But so long as you enroll the kid in extracurricular class or activity that introduces them to other kids they're generally better off.

>>60377350
>>60377479
If you want a more advanced calculator the best place to look for one is finding out which ones can't be used on a standardized test those ones retain absolutely no fucking value whatsoever, but are generally far more powerful than the ones that are using standardized tests.

Whenever a teacher would show us how to do something on a graphing calculator they would only show how to do it on a TI, but it wasn't too hard to figure out how to translate the directions to Casio.

Former math teacher here. There's several factors. Some legitimate, some not.

* Graphing calculators have a battery life measured in months if not years.

* Even though any smartphone has a hundred apps with a hundred times the functionality of a graphing calculator, you can't use a graphing calculator to text in class, send photos of tests to friends, or get wolframalpha to do your work for you.

* TI's are great for numeric calculations and plugging values into functions and graphing. They're nigh-useless for any kind of symbolic manipulation. This is the sweet spot of capability if your intention is to facilitate *learning* symbolic manipulation (i.e. algebra).

* TI is in bed with Big Textbook. Almost every textbook comes with instructions for using TI calculators right in the lessons. This means teachers can say "just read the textbook." Teachers love this.

* For most math teachers sending an email with a document attached is a monumental technical achievement. Learning how to use more than one kind of calculator is an inconceivably arduous prospect.

* Because you *have* to buy one for school, TI can charge whatever they want.

Go fuck yourselves, Texas Instruments. This was a little while after I watched the based LGR video all about how shady TI is. Luckily for me through some various connections I got a hold of someone else's that they weren't gonna be using anyways, so none of my money (or parents') ever went to them in the first place for a brand new one.

I also found out through a little bit of digging that you can in fact actually equip one of these things with a wireless radio and you can effectively "communicate" between it and something else, I think it was through Bluetooth. It seems like it'd require a bit of setup, but if you can set such a thing up and actually bring it in to something where communication would ACTUALLY be an issue (like a test or exam, but the issue was because of just some textbook shit) and actually not get detected and can cheat your way through, you should deserve to pass.
Here's that very video as a matter of fact, just pair your stuff before the exam (try and do it discreetly for obvious reasons), walk in, then have the person with a phone sit conveniently near the test/exam location and feed you answers: https://www.youtube.com/watch?v=KWa6manhKcQ

What a joke that "nothing that can communicate with other things" rule is when I realized you could do that.

But really, why would you use a calculator for that? I don't know how americans do their thing, but here in europe there is absolutely no use for these things.

Most graphing calculators have a CAS these days, so they're useful for all kinds of tasks. A calculator is useful because it's small enough to always take with you, if you're an engineer or scientist or mathematician or whatever, and it'll run for a long time on batteries.

A lot of people still like their HP-48 series calculators because they interface with anything with RS-232, you can use them for data collection or even as a terminal to log into a computer in the field.

>I am honestly interested, who use these things? Being in engineering industry I've never encountered anyone who would use such a calculator.
All kinds of people in engineering, computer science, communications, banking, finance, physics, land surveying, and so on use calculators every day. I'm a little shocked that you never run across people who use calculators. Bear in mind the mere capability for plotting and graphing doesn't imply this is their major use case. Most people don't touch it but the bigger screen is nice for matrices and so on.

>This seems super innefficient. I don't really imagine a scenario where one would use a graphing calculator. If you are solving an engineering problem, you will use a simple scientific calculator + paper. If the problem if more complicated you will use computer.
You don't know how RPN makes it very easy to play with numbers and calculations, do you. This is the problem with being a postfix-let. You don't know what you're missing.

>I might be missing something. What would be realistic scenarios?
For me RPN / RPL is one of the major reasons I like to use a calculator over a computer. This entry and calculation method makes it really easy to do repeated calculations with different inputs, go back and "undo" your steps, and write short programs as easily as entering calculations manually. I'm a radio ham and RPN / RPL is useful for my experimental activities, the HP-48 series comes with a bunch of built in physics tools and a periodic table which is useful if you're into physics, radio, electronics, hydrology, etc.

If you're working on an oil pipeline or a survey line or something like that and are away from civilization you're probably not going to want to carry or fool with smartphones or laptops or touchscreen tablets to do your work either. Land survey equipment is still being made to interface with the HP-48 and HP-50G.

TI calcs are all modal and it's really hard to move between different types of math and make it all work together, this is one of my biggest complaints.

HP's RPN/RPL environment makes it easy to do this on the other hand, because no matter which features you're using everything happens on the stack. RPN has a reputation for being hard to learn but I think it's easier to actually use once you spend one hour, one time, learning how it all works together.

Sadly HP is moving away from this with their new Prime calculator, it's a full color gee-whiz thing which has a relatively short battery life and is hard to program and use, with a kind of strapped-on RPN front end which is strictly optional.

>>60383542
It's a TI-92 Plus, basically the same exact calculator they sell today except from the 1990s and in a larger, landscape format with a much better screen.

Batteries last longer too, my wife uses one and I installed lithiums like 2-3 years ago, still going strong.

My high school gave out TI 84's to all students to keep. My university gave each engineering student a TI 36x Pro. I use what is free to me.

It's perfectly understandable to normies, anon. The user interface of HP calculators and keystroke RPN had a lot of thought and research put into it.

>And the higher level languages HP and Ti "designed" also are trash.
TI BASIC and variants range from utter shit to decent for the time. HP's RPL is a brilliant environment and once you know how to use it everything else feels cripplingly bad. Some French hacker put together development tools for the 48G series and HP included it in the 50G, it's really great actually. If you like you can also compile whatever you with with GCC or even run it on the 50G of course. There is also a new effort, now mostly finished, to implement a new ground-up but 48/50 compatible RPL environment which is more portable, but this is targeting the 50G for now despite the idea that it will run on other hardware in the future.

Brainlets need not apply, as usual.

>>60371396
Not on this side of the pond.
Also why do you even need graph cals for high school tier math??? We were banned from using them during exams anyway and the first time we were allowed was in uni but by then everyone was just using Matlab on a laptop.
I guess it was the "If you can do it by hand you can do it with tech later" approach...

>>60402504
I see a lot of people who use calculators. But when have to do some calcuations they usually break out excel. I mean, endless grids, formulas till you drop. When integration, differentiation is involved and CAS is generally needed they resolve to mathcad/matlab and something similar.
