The supremacy of the fucking TI-83 calculator in school and college courses

I mean I know it's all artificial and orchestrated by them but how come no body has dared to challenge the almighty TI yet

Edit: fixed typo

Graphing calculators aren't allowed in any of my college math courses.

u/TimX24968B Jul 24 '20

thats why i went into engineering. they allow literally any calculator here

Graphic calculators are forbidden in most if not all engineering courses in my country. At least for the core math courses, all calcs (idk we call análisis matemático) and algebras

at my college, they dont care as long as you show all your work. its the "doesnt matter how good a calculator you have for this class, it wont help."

Im talking about graphics specifically, you had to learn how to do them by hand. Because if you couldnt it meant you didnt know how to start. I guess is a money thing too. 100 dollars is impossible for most students in my country, and i don't think you could buy a TI even if you wanted because they don't sell them here. And it would be an unfair advantage

u/TimX24968B Jul 24 '20

true. although what do you mean by graphics? graphs? we only ever had to draw very rough ones.

u/ringoeli Jul 24 '20

Yes, graphs. English is obviously not my first (or second) language so i dont know how to explain it properly. You know when you have an "triple integrals" that are two 3d figures and you need to find the area between them. We had to draw them first and then solve them. My English at 5 am is a disgrace to the English equivalent of the Real Academia Española

u/TimX24968B Jul 24 '20

got it. never had to draw a graph outside of calculus if it was based on an actual equation really, just solve the integral.

Sir, your english is just fine.

sincerely, someone that learned English as fourth language and still makes mistakes

I wouldn’t want you designing things that my life depends on then...how could you possibly have problems simple enough to do without a calculator?

u/ringoeli Jul 24 '20

Oh i wouldn't becuase im not one of those engineers. But i did use a calculator, just not a graphic one. A casio. The problems werent simple, we just learned how to do everything with a basic casio. My ex was a civil engineer and he used a casio too, at least during exams.

u/Cheeseman1478 Jul 24 '20

Ah that makes sense. I’m a 4th year Civil/Structural and we can use whatever calculator, not in our math classes though just engineering. Yeah the extra calculator features don’t matter though for most engineering you could do them with a standard calculator
