Re: Ti-84 Evo
#173We had to buy those calculators for highschool and it was a waste of money, felt like somebody must be paying somebody off to have thousands of students buy a device that they will certainly never have to use (and is of little educational value).
I sort of agree. You're paying $100 for completely antiquated hardware where its core feature is "it doesn't do much". Pretty much any professional environment that you will need calculations will have access to a computer that can do these calculations significantly faster and better. I thought my HP was pretty cool in high school, but pretty much the moment I graduated I stopped using it because I figured out how t…
Well I'd add to that - the real core feature is that the teacher and usually the textbook show you exactly how to use it, that's why it gets listed specifically as a course requirement.
That unfortunately is also why they can charge so much and people buy them anyway, because at best you'll be on your own to learn how to use anything else (and at worst you won't be allowed to use it at all for tests and such).

There's even knockoffs of it for $1: https://www.aliexpress.us/item/3256809744184708.html I picked one up when the 99 cent store was shutting down. It works fine.

Generating a QR code to see the graph online is kind of cool, but also kinda dumb too. I mean, these days kids have smartphones, what's the point of a graphing calculator?
>kids have smartphones, what's the point of a graphing calculator?
Many tests will not allow you to use a smartphone. My son couldn't even use the school issued chromebook on his PSAT, he had to get a loaner Windows laptop or use an approved hard calculator.

International Baccalaureate math has some stats questions that require a calculator that can do stats questions. Not really possible by hand in exam conditions!
HL or SL? (It's been a while for me, but I know I needed PDF/CDF functions... and I don't know about the optional modules/Further.)

Well, the TI-83/84 are called a graphing calculators for a reason: you can plot equations and datasets with them and look at them right there[1]. Looking at graphs is huge for learning, or at least it was for me, and school isn't just about plugging things in and getting an answer (or shouldn't be, at least).
Doesn't mean it's not overpriced, but that's one reason and you can get a used TI-83/84 for like $30 or less. They pretty much never break.

1. Okay, the Casio can QR-code-link you to a graph, but if I have internet/smartphone there are better graphing tools anyway, like Desmos.

Apparently, you can use it in RPN mode!
Re: Ti-84 Evo
#178About 25 years ago my parents got me a Ti84 as a surprise for Christmas and they hid it in the attic so I couldn't find it in the meantime. A few months went by and a couple days before Christmas, when it was time to wrap the presents they couldn't find it anymore. My dad went out and got a Casio something as a late minute replacement, and that was the calculator I used in high school and I never knew about this stor…
Must have been closer to 20 years, 84(+) didn't come out until 2004.
Gonna be pedantic/crotchety about this because I got into advanced math classes but it was my brother who got the 84+ (I had to settle for a 83+). Guess who's the engineer now, and who's the NEET? Your kids pay attention to what (who) you value, folks.

If you count basic calculus as high school level, TI89's can do symbolic integration. They're usually banned on tests for that exact reason tho.

Real shame since cortex has a admin TrustZone processor that is licensed to special interests only. For the educational market, this "security" is a selling point. It guarantees that a student isn't running unauthorized code or "cheating" apps. It also likely allows OTA auditing of the classroom's state.
Any secure boot design can achieve that, you don't need TrustZone to do that
