But you still need the TI-89 Rom to be able to use it.

Good to know graphic calculators haven't fallen in price since I was in high school....
this is what happens when there's gov intervention.
this exact model calc is required by many schools to study, and the *one* approved calc for taking exam.

I graduated a year ago with a math/stats degree and I got through every class using a $20 TI-30XS multiview. That includes the typical high level math classes (multi-variable calc, Linear algebra, and the highest level probability and statistics courses). I didn't need any form of a graphing calculator once.

The teachers that require it are most likely uneducated high school math teachers. I remember my high school stats and calc teachers making me buy a graphing calc. What a waste of money
I have to call BS on this. You earned a degree in "math/stats", not usually how a mathematician speaks. Further, this calculator you reference states that it's for "high school math", yet you were solving partial differential equations on yours? If you really did what you've claimed, then you're truly a brilliant person. Just know that the average person will need the tools that are recommended by the person teaching the subject. Visualization is a powerful learning tool, don't discount it to save $50. To imply a teacher is lesser because they recommend a calculator out of your desired price range is ludicrous, btw...

CS/math minor here, graphing calcs are banned from where I went to school, highest you can have is the 36x pro. Which is the same for engineering exams.

I remember impressing everyone with Super Mario Bros on my TI-89! Plus that was the first calculator that you could type an equation in and have it solve for x.

Thus the reason I'm even worse at math than I should be Frown

Also when I took algebra in college they didn't even allow graphing calcs on tests. I don't remember if my buddy was even allowed to have on in his calc classes

Haha, this is cool if smartphones didn't exist. TI sat on their monopoly for thirty years without innovating or lowering prices and now they want to lower prices on their top tech. About twenty years too late

BRING BACK THE 89! I'll bet it can do the same thing as this "NEW SPACE AGE" technology they are trying to sell.

Anyone know what the difference is from the old cx cas to the new one? I can't seem to find.
The big thing on this model is that 3D has been added to this version vs the first version. Not sure if that helps

These are like expensive college text books...

But somehow TI has figured out how to keep making the same one repeatedly without a cheap chinease knock off coping them.

Amazed there isn't a $10 "Xetas Chinstruments" version of these calculators by now...
No, the reason they can do this is because they have a deal with the education board. It's basically an indefinite contract. Instead of paying teachers, we're paying TI for overpriced calculators.

This is insane, you're just making shit up, you don't solve diff-eq with a calculator, most of the time you don't solve them at all, in high lvl courses I've taken, I was instructed to demonstrate a few steps, and skip any tedious number work that comes up, obviating any calculator use, because data-entry is not what you're there to learn.

And the poster you reponded to is correct, you don't need a graphing calculator for the majority of college math courses.

In the rare case, you might use graphing to find an asymptote or decide on a solve strategy, but this is rare and only in very specific courses.

I tried this, and ebay. Sadly we needed a specific one, and my kid isnt super at math so I didnt need her trying to figure out a substitute calculator AND her math. Since this price was pretty competitive (even compared to CL and ebay), I bought from google express. Then I posted for others in my position. Its freaking crazy.Frown
Very sad. Spending money on a tool building skills someone will never use. Unless this is for probability or accounting, it's just a giant waste of time and energy.
