Once again a new school year is top top us, and also that requires a new look at the TI-Nspire CX CAS vs. TI-89 Titanium debate. In addition to this article, you may want to check out my standalone TI-Nspire CX CAS Review and also my TI-89 Titanium Review. I wrote a short article on this object a couple of year ago, but with each passing year it needs to be updated. Texas instruments has continued to update the TI-Nspire CAS platform, a year earlier releasing the TI-Nspire CX CAS, a color version the the CAS. Then, this summer, they release OS 3.2, a cost-free upgrade come the TI-Nspire platform that functions on every version of the CAS, also the original “clickpad.”

If you’re heading into calculus, there’s a an excellent chance you’re wrestling v the inquiry of the TI-89 Titanium vs. The TI-Nspire CX CAS. They space the most famous Texas tools graphing calculators v that have the computer algebra system. I’ve provided both of this calculators generally with the math team i coach. If you need the Cliff note version, allow me phone call you that in the year 2012, the TI-Nspire CX CAS is the clear reduced winner. For those of friend who have the patience because that a an ext detailed review, please read on.

Computer Algebra Systems

First off, you need to know that both of this calculators function a computer Algebra System, or CAS. That method you can go into variables favor x or y, and also the calculator is qualified of performing to work such together simplifying expressions or resolving equations (think x + x = 2x). Of course, this is simply the beginning, as the CAS can handle all kinds the algebraic manipulations native factoring come differential equations.

While these attributes are awesome, you should be careful when to buy a CAS allowed calculator. They room not enabled on the ACT, although many models, including all versions of the TI-89 and also TI-Nspire CAS models, are simply fine because that the SAT and also AP tests. That makes these calculators a popular an option for calculus classes, however if you’re planning to take it the plot you might want to think about the non-CAS version of the Nspire CX.

Why select the TI-89 Titanium Edition?



A big drawback v the TI-89 is its lack of “mathprint” inputting, likewise known together pretty print. You can set the calculator up so that once you press enter, your occupational will be reformatted to look favor what you view in the book. Unfortunately, you can’t do the input that means (see right). If you’re a calculus student, that’s probably not a huge deal to you with exponents or radicals. However, as soon as you’re learning summations and integrals, that is one much more thing to problem about, and it have the right to be difficult to psychic what every term in the list of input represents.

Why select the TI-Nspire CX CAS?



At one point, over there was additionally the concern by part calculus students that the TI-Nspire CX CAS was absent differential equations capabilities. Those abilities have actually been included to all TI-Nspire CAS versions, therefore this is no longer an issue. However, since the TI-89 Titanium is enlarge and more of a programmer familiar calculator, girlfriend may uncover that there are calculus apps/programs available for that that are not easily accessible for the TI-Nspire CX CAS. 

For teachers, the TI-Nspire CAS collection has dynamic capabilities that can’t be matched by any other graphing calculator. Together a an easy example, top top one display screen you deserve to have a graph, that is equation, and its table. Use the allude and click touchpad to traction the graph into one more shape, and the equation and table will readjust in sync. The applications of this sort of interconnectedness in between data depictions are endless. Generally speaking, the TI-Nspire CX CAS is simply plain far better as a learning an equipment in virtually every way. In enhancement to simple inputs that equations and also algebraic commands, it likewise has geometry software, notes features, and also spreadsheet ability the TI-89 Titanium can’t touch.

Bottom Line

As lot as ns love both of this calculators, in a head to head battle, I’ve got to recommend picking increase a TI-Nspire CX CAS. I went with the Nspire CAS for my mathematics team and also have uncovered it to be a an excellent decision. We won the Illinois state math team championship this previous spring, and also I certainly attribute few of our success to the CAS. It’s got all of the latest bells and also whistles, a much better display, and also I uncover it much, much much easier to usage than the TI-89 Titanium (and so perform my student that use it every day), mainly because of its graphing interface and math publish inputting. Now that Texas instruments has provided differential equations, 3D graphing, and also color capabilities to the TI-Nspire CX CAS, it’s bring away the collection to a whole brand-new level. I’m really only scratching the surface of what the TI-Nspire CX CAS can do in this review. 

If friend have any type of trouble acquiring started through your CAS, inspect out my publication TI-Nspire Tutorials Vol 2: utilizing CAS attributes like a Champion. You have the right to learn the same methods I use with my math team student on the CAS.
