Once aget a new school year is upon us, and also that needs a fresh look at the TI-Nspire CX CAS vs. TI-89 Titanium dispute. In addition to this short article, you may desire to check out my standalone TI-Nspire CX CAS Review and my TI-89 Titanium Review. I created a short article on this topic a couple of years back, but via each passing year it hregarding be updated. Texas Instruments has continued to update the TI-Nspire CAS platcreate, a year back releasing the TI-Nspire CX CAS, a shade variation of the CAS. Then, this summer, they release OS 3.2, a totally free upgrade to the TI-Nspire platcreate that functions on every version of the CAS, also the original “clickpad.”

If you’re heading into calculus, there’s a great chance you’re wrestling via the question of the TI-89 Titanium vs. the TI-Nspire CX CAS. They are the most renowned Texas Instruments graphing calculators with that have the computer algebra device. I’ve supplied both of these calculators extensively with the math team I coach. If you need the Cliff Notes version, let me tell you that in the year 2012, the TI-Nspire CX CAS is the clear cut winner. For those of you who have the patience for an extra thorough testimonial, please read on.

Computer Algebra Systems

First off, you must understand that both of these calculators feature a Computer Algebra System, or CAS. That implies you can enter variables favor x or y, and also the calculator is qualified of performing operations such as simplifying expressions or fixing equations (think x + x = 2x). Of course, this is simply the beginning, as the CAS can manage all kinds of algebraic manipulations from factoring to differential equations.

While these functions are awesome, you should be cautious when buying a CAS allowed calculator. They are not enabled on the ACT, although a lot of models, including all versions of the TI-89 and also TI-Nspire CAS models, are simply fine for the SAT and AP tests. That renders these calculators a renowned option for calculus classes, yet if you’re planning to take the ACT you may desire to consider the non-CAS variation of the Nspire CX.

Why Choose the TI-89 Titanium Edition?

A big drawearlier with the TI-89 is its lack of “mathprint” inplacing, likewise known as pretty print. You have the right to set the calculator up so that when you press enter, your work will certainly be reformatted to look favor what you view in the book. Unfortunately, you can’t carry out the inputs that method (view right). If you’re a calculus student, that’s probably not a big deal to you with exponents or radicals. However, as soon as you’re finding out summations and also integrals, it is another point to worry around, and also it can be difficult to remember what each term in the list of inputs represents.

At one suggest, tright here was likewise the issue by some calculus students that the TI-Nspire CX CAS was lacking differential equations capabilities. Those abilities have been included to all TI-Nspire CAS versions, so this is no much longer an issue. However before, since the TI-89 Titanium is older and even more of a programmer friendly calculator, you might uncover that there are calculus apps/programs accessible for it that are not available for the TI-Nspire CX CAS. 

For teachers, the TI-Nspire CAS series has dynamic capabilities that can’t be matched by any type of various other graphing calculator. As a simple instance, on one screen you have the right to have a graph, its equation, and also its table. Use the point and also click touchpad to drag the graph right into an additional form, and the equation and also table will change in sync. The applications of this kind of interconnectedness between information representations are endmuch less. Normally speaking, the TI-Nspire CX CAS is simply ordinary much better as a discovering gadget in virtually every method. In addition to simplifying inputs of equations and also algebraic regulates, it additionally has geometry software, notes functions, and spreadsheet capabilities the TI-89 Titanium can’t touch.

Bottom Line

As much as I love both of these calculators, in a head to head fight, I’ve acquired to recommend picking up a TI-Nspire CX CAS. I went via the Nspire CAS for my math team and have actually found it to be an excellent decision. We won the Illinois state math team championship this previous spring, and I certainly attribute some of our success to the CAS. It’s obtained every one of the latest bells and also whistles, a better screen, and also I find it a lot, much less complicated to usage than the TI-89 Titanium (and also so do my students that usage it eexceptionally day), largely because of its graphing interconfront and math print inputting. Now that Texas Instruments has given differential equations, 3D graphing, and also color capabilities to the TI-Nspire CX CAS, it’s taken the series to a whole brand-new level. I’m really just scratching the surface of what the TI-Nspire CX CAS have the right to execute in this testimonial. 

If you have any kind of trouble gaining started via your CAS, examine out my book TI-Nspire Tutorials Vol 2: Using CAS Features favor a Champion. You deserve to learn the very same techniques I usage through my math team students on the CAS.
