Ti 89 Titanium or Ti nspire cx cas
Heading to college in a month so I think it might be a good time to retire my 6 year old 83 plus and get a new one. I've narrowed it down to these two because I plan on majoring in engineering (electrical, chemical, biomedical, computer (science) or mechanical; still undecided). But idk which one to get as the 89 has a button layout akin to my 83, but I've read from numerous sources that the nspire trumps the 89 once you get used to it. However, I've also read that the 89 is much more versatile when it comes to programming. I'm starting at calc 2, so the pretty print on the nspire is a godsend when inputting integrals, but I do know the order of input from my 83, so it wouldn't be that bad, but pretty print is amazing. My college permits the use of both calculators on exams, in case that was a factor. Obviously both of these calculators will aid me immensely, but which one would be more beneficial to an engineer?

[quote=Yumtoast]Except SE majors are only required to take general engineering courses and hypergeometric series are an integral part of probability theory (a 2-tier course for applied math minors/majors and CS/SE students). As for matrices, if programmable calculators aren't allowed at whatever sticks school you attend, try bringing your computer to an exam. And I don't know about you, but half the courses I listed are upper division courses -- though it seems like that missed your head entirely.
Jesus Christ, you have absolutely no right to talk trash considering you didn't even completely read my post or OP's post. Why are you so against OP using a programmable graphing calculator when they [b]are allowed[/b] at his university? Get your head of your ass.[/quote]
I actually go to university and they aren't allowed so I am letting OP know that he doesn't need one. I don't list some high school/low level courses to convince the OP that I actually know what im talking aobut. In second year ordinary differential equations and linear algebra I solved 4x4 up to 6x6 matrices by hand just as a preliminary to actually solve math problems and here you come off making it sound like you need a computer to solve "4x4 matrices"
[quote=Avatar]LMAO you are are in fourth year university listing only first to second year classes like calculus and general engineering you are so smart you think I was going to buy that? oh no 4x4 matrices better get my computer to solve that. OP if you are still reading this thread ignore this person he doesn't know what he is talking about. Trying to fool people by using the word hypergeomtric lmao you don't even know what it is.[/quote]

[quote=Yumtoast]@Avatar: I'll be a 4th year this fall (SE major, AppMath minor), and I've used a TI-84 in:
Math courses:
Combinatorics
Linear Algebra
Calculus II
Calculus III
Probability Theory
Everything else:
Classical Mechanics
Light & Magnetism
Algorithms & Data Structures
General Engineering
etc
If your professor isn't an incompetent piece of tenure trash, you'll be able to use TI-83 and above calculators. There's no way in hell I'm going to calculate hypergeometric series or 4x4 matrices with a $10, 12-digit scientific calculator. Not only that, but it's incredibly easy to spot calculator-answered integrals (or other problems, if a particular class prohibits that), and proctors should be checking for any programs on your calculator before an exam.
Also, if you read what OP posted, he explicitly stated that both the TI-89 and Nspire are permitted at his university.[/quote]

[quote=Yumtoast]Except TI calculators are the standard in statistics, calculus, and algebra courses in college.[/quote]
except that im in third year university and they are not
[quote=Avatar]In university you are not allowed to use programmable calculators on examinations so buy one of those staple brands or something preferably those that show fractions (that will help you a lot in a math course).[/quote]

Just get a normal ti 83 to solve calculus problems for hw. For exams you won't be allowed to use it like people said above.
a ti 83 will work fine for engineering, trust
looool, forget those graphing ti calculator
check your college's approved calculator list to buy a calculator
maybe you can rent graphing calculators there, test them out first
I am the same as above. Your university will tell you which calculators are allowed. There are actually only two calculators allowed at my university. It's funny because I had used one of the two models listed from high school, so I didn't need to spend more money on a new calculator.
Anyways, I recommend any cheap calculator that can do complex numbers, it can be really useful (Sharp El-520 is the one I use).
