Reddit reviews Texas Instruments Nspire CX CAS Graphing Calculator

Just recently bought the new nspire cas. Still getting used to it but man is it sweet. Much more modern and easier to use than my 89 that went missing one day

I am a sophomore cs student going into my 4th semester. Here's my experience with the calculator policies for tests in different classes:

• Math: No calculator allowed or only a 4-function allowed.
  
• Physics: Any calculator allowed except for those expensive TI Nspire CX ones with like LED screens. They never checked during exams. Also formula sheets were allowed for exams so you only ever needed the basic functions anyway.
  
• CS: Never needed a calculator for any cs classes.
  
  I always use a TI-84 cause that's just what I own, but I really only use it for the screen size. Any calculations can be done on a 4-function or scientific calculator like you have. When I don't have a calculator with me, I'm able to use my phone calculator app or try to always keep wolfram alpha or symbolab open in a tab on my computer which is helpful for explaining stuff and a larger range of calculations. In other words, you should be fine with the scientific calculator for 1035 that you have, but a more expensive one will make calculations easier, faster, and possibly more accurate (in my experience the keys on the scientific calculators don't register sometimes and are less sensitive than the nicer calculators, which can mess up a calculation - pain in the ass when you don't realize a button didn't register at the beginning of a multi step calculation until after the fact). There are a lot of ti-83's and ti-84's on eBay that are pretty cheap. I just looked and the first couple results were all under/around $40. Hope this helps!

and it costs about as much as a regular graphing calculator

Same here I'm staring my 3rd year in ME. I've got a TI NSPIRE CX CAS (my school allows it during exams). It does 2D and 3D graphs, it s rechargeable, in color, programmable and does pretty much everything. There s a nice solve function to automaticaly solve equations (even with multiple variables). It also comes with a desktop sofware.

If you want an absolute beast of a calculator, I recommend the TI-nspire CX Cas.

It can do anything and everything. It has gotten me through many classes. It can do Complex/Imaginary matrix operations, can graph 3D functions, can solve ODE's, and you can program it to accomplish various tasks.

I got the TI Nspire CX CAS for my last couple years of my BSME and I cannot recommend it more! It does everything! Basically a step above the TI-89 but thinner and faster with a color screen and a rechargeable battery.

I got the new N-Spire CX CAS . It's dope. Color screen, indefinite integrals, rechargeable battery. Also unlimited nerd cred. I've used it to solve annoying integrals saving me tons of time on tests. (Mech E)

i have 2 calculators, the first casio 115ES is allowed on the FE exam (Fundamentals of Engineering) that you take upon graduation so its good to be familiar with it

Casio 115ES has a natural display thats unbelieveably good, much better than other 115 series casio.

$14 http://www.amazon.com/gp/product/B000A3IAHM/ref=oh_details_o03_s00_i01

the seconds is a TI N-spire CX CAS (Computer Algebra System)
it allows you to solve any equations symbolically ex: integrating from x to infinity using x and infinity as terms..

it will probably not be allowed on exams but for $144 from amazon it has a color screen and touchpad mouse cursor and is within 2 years old and will be relevant for the forseeable future

Actually, calculator - $138.

They also have some really fancy graphing ones.

I have a CX CAS I was thinking about selling if you want it.

I'll let it go for $80

There were mandatory for us

I don't know what major you are but if you are in engineering I would strongly recommend one of these for a little bit more:

If you are seriously looking for a calc and can use whatever one you want you should get this:

It's cheaper and a better calc. though it is still quite overpriced compared to a cellphone :D

Is it this one? If so I waaaant it. Getting used to the new interface will definitely be a bitch, but it'll be a much better utility to me once I master it.

It's around $150 on Amazon...

CE here (4th year). Had an 84 Plus coming in, bought the nspire cas a year ago and extremely happy with it. It's honestly not that much more $ than a new 89 (get CAS because complex number math). Really nice functionality, matrix solvers, statistics stuff. Didn't need it for first year but later math courses it has been quite helpful. My EE buddy is always stealing my calculator for his exams :). If you have questions feel free to ask.

I’m going off what I have seen, and the ones I have seen are more of a brick.

Not defending TI here, but this looks a bit nicer than what I had in high school:

For general number crunching I use my trusty TI-36x. It's $20, does definite integration and derivation and pretty much everything else that a TI-84 does (minus the graphing). It's also solar powered and rather small.

For heavy duty calculations I use my TI Nspire CAS

TI36x Pro: http://www.amazon.com/Texas-Instruments-36PRO-TBL-1L1/dp/B004NBZB2Y/ref=sr_1_1?ie=UTF8&qid=1407807454&sr=8-1&keywords=ti36x

OP has this calculator, not the bottom tier you linked.
