Reddit reviews Texas Instruments TI-Nspire CX Graphing Calculator

You would be surprised

It fucking beats me why this peice of junk still costs so much

I raise you for best calculator

Do you guys really still use TI-84s? The TI nspire is way better and cost like $20 more tops.

I like the TI-Nspire CX better. It's a damn nice calculator.

For those who are curious it's $127 on amazon.

$134.62 on Amazon!! The TI-84 Silver Edition is $119 on Amazon, so that's not that big of a jump

Okay I just checked the prices and I realize it's not that expensive. It's just above a $100 on Amazon which is a pretty good deal (considering you buy refurbished and not new.)

TIL.

Or for $4 more: http://www.amazon.com/Texas-Instruments-TI-Nspire-Graphing-Calculator/dp/B004NBZAW0/ref=sr_1_5?s=electronics&ie=UTF8&qid=1377710854&sr=1-5

This is the one I have. It gets me the bitches, although I am only going into Pre-Calculus.

I have a Ti-nspire CX, selling for $75 shipped. Best graphing calculator you can get.

>I believe that the government should require that all publically funded schools accept all graphing calculators regardless of who produces them or what brand they are and instead bases them off of functions necessary to complete the curriculum.

Already you can use any graphing calculator. Incidentally, there are numerous calculator companies in business. Do you mean for the government to impose penalties on schools that recommend a specific graphing calculator to complete the course? What kind of law do you want to make and what would it say?

Aside: there are legitimate reasons to ban graphing calculators that are too good in classrooms. If there is a test on integration, having a calculator that can show you step-by-step symbolic solutions can invalidate that test. You can argue that being able to integrate by hand is a stupid skill that's not worth learning, but that's a very separate argument.

See more SAT rules for calculators here. Both for a stunningly long list of competitive graphing calculators and for some features that are banned in some testing situations.

>So, for starters because of the textbook industry the use of the TI-83/84 has run rampant and has monopolistic competition on college campuses (and thus relevant work places) as a result.

So? It's tried and true. I work in finance, and we all all use Dixon Ticonderoga pencils because they work. Oh, and we all have HP-12cs, lol. Would you propose a law banning Dixon Ticonderoga because their lead is too smooth, and their grip is so light, and their eraser too supple? "Your product is too good! Destroy it and design it again!"

>This monopolistic competition allows them to charge up to $150 for a Calculator that has not been improved upon since 1996.

So? Lots of things aren't cheaper than they used to be.

>Today most phones (even non smartphones) are more powerful than both of these calculators in terms of raw hardware.

I hate responding to every single one of your points with "So?" but really: "So?"

What, specifically, do you want a graphing calculator to do that it can't do? Keep in mind also that there are way better graphing calculators out there, just nobody buys them because the purpose of a graphing calculator is to help students learn math skills more than it is actually used to solve problems.

I can't honestly think of a single function I want on my TI-84 (as a learning/educational tool) that it doesn't have. It would be nice if it were faster, I guess, but it doesn't make sense for them to redesign an entire calculator just to make it as fast as your dumb phone.

It does everything that you want it to do.

If you are taking more than 3 of MathHL/physics/chem/econ then it would be a great investment.

Sooo many versions of the 89 and I dont know what the differences are. There's the 89, 89+, 89 silver, 89+ silver & 89 titanium.

Here's a link to the Nspire, its a relativly new model, has a color screen & touch pad.

TI-nspire CX no question

Just a few more dollars than an 84+ Silver Edition on amazon.

It's got a faster processor, more RAM/ROM, color screen, better controls, overall a calculator for this generation. The 84 series is from the early 2000s I believe in this model is a lot more recent.

Plus I just bought one and all the 84 users in my math class are jealous of its beauty.
