What are the Similarities Between the TI-89 Titanium and TI-Nspire CX CAS?

Though the TI-89 Titanium and the TI-Nspire CX CAS are two very different calculators, you should be able to perform similar functions on both machines. They should also provide the same answers.

Both calculators have a Computer Algebra System making them smarter than the average calculator. This also ensures that they are both capable of handling logarithms, though logarithms may be limited on the TI-89 Titanium, and even doing 3D modeling.

Both calculators also accept information or data from a computer or fellow calculator using the provided linking cables. Both calculators are also great for a variety of classes. These include statistics, chemistry, calculus, linear algebra, and many more. Surprisingly, images can also be used on both calculators.

What are the Differences Between the TI-89 Titanium and TI-Inspire CX CAS?

Being that these calculators were created so far apart, there are a number of notable differences between the TI-89 Titanium and the TI-Nspire CX CAS. Visually, there is already a stark contrast between the two calculators. The TI-Nspire CX CAS is roughly half the thickness of the TI-89 Titanium and more lightweight.

There is also a visible difference in the screens and the button layout. The TI-Nspire CX CAS offers a full-color 320X240 pixel backlit display, whereas the TI-89 Titanium provides a 100 X 160-pixel noncolor display. Another noticeable change to the physical makeup is that the TI-Nspire delivers a full keyboard along the bottom of the device. The TI-Nspire CX CAS also introduces a more rectangular shape than the oval shape of the TI-89 Titanium.

The power supply for each calculator is also different and affects its performance. The TI-89 Titanium uses four triple-A batteries, whereas the TI-Nspire uses a rechargeable battery that won't need to be replaced for years on end.

Solving equations on both calculators is also different. Aside from the noticeably different screen resolution, equations can be answered on the TI-Nspire CAS CX using a simple solve command.

FAQ When Deciding TI-89 Titanium vs. TI-Nspire CX CAS

What are the warranties on these TI calculators?

Both the TI-Nspire CX CAS and the TI-89 Titanium come with limited warranties with Texas Instrument.

The one year warranty begins one year from the time of purchase. In the event that the calculator is found to be defective in materials or craft, Texas Instrument will replace it with a refurbished calculator of the same model. However, Texas Instrument reserves the right to refuse a calculator do to the nature of the damage. Calculators that were damaged accidentally or through unreasonable use will not be replaced under warranty.

If support is needed, Texas Instrument provides an email helpline as well as a calling hotline.

If using a calculator like the TI-Nspire CX CAS, it is recommended that you utilize the provided USB cable and adapter. Third-party chargers should not be used as they may not offer the same effect. There is no warranty provided for the charging cable and USB.

Can I use these calculators on my college entrance exams (AP, PSAT, SAT, ACT)?

One of the most important things to consider when purchasing a calculator is its ability to be used on standardized tests. This is especially important if you are a high school student, and that is your primary need for the calculator.

Fortunately, both the TI-89 Titanium and TI-Nspire CX CAS can be used on standardized exams. However, which tests they can be used on are limited. The exam that bans the use of the TI-89 Titanium and the TI-Nspire CX CAS is the ACT. Tests that allow for the use of both calculators include the SAT, PSAT, and all AP exams. Individual restrictions to your classes will need to be handled through your school or your course's respective department. Both calculators are also permitted on the IB exam.

Which calculator should I use for Statistics? Physics? Calculus?

You can use a calculator for virtually anything; however, when thinking about specific subjects that require more depth and complicated equations, specific functions are needed. The TI-Nspire CX CAS has the ability to work for Statistics, Physics, and Calculus. There are several programs that come stock, as well as ones that can be downloaded to your calculator to make it function the way that you need it to.

There are several functions on your calculator which will support its use with Calculus. These include:

Graphing derivatives
Solving derivatives
Integrals
Limits

In addition to these calculus functions, there are several others for physics and statistics. Some of these options also come pre-downloaded on the calculator, as well. For statistics, users have the opportunity to do hypothesis testing, distribution functions, various plot types, and even one & two-variable statistical analysis.

With regard to physics, much like statistics, users have the ability to download a variety of applications that will help them in their courses. This includes programs like Physics Formulas and Workspace 2.0, Science Nspired, and many more. Several students rave about the calculators' ability to help them quickly check their work for a multitude of problems.

Should I care about backlit screens?

Backlit screens are by no means a necessity for a calculator, though they are nice to have. They allow your screen an added glow that you normally would not have if it is not lit from the backside. It does make your view cleaner and crisper, but it will not change your calculator's functionality.

Is CAS worth the money?

Think about what you plan on using your calculator for. Will you be complex graphing functions or solving matrices? Will you need to use the chemistry functions or be solving for integrals? If you are simply using your calculator for basic arithmetic, then no, CAS would not be worth the money.

However, if you plan on going into a STEM field or a field with ample math, a CAS calculator would be a significant investment. It would also last through your college career and potentially after depending on the calculator you opt to purchase. Being that CAS allows you to rid yourself of the manual steps needed to solve a problem, it is great for standardized tests.

Wrapping Things Up: TI-89 Titanium vs. TI-Nspire CX CAS

Overall, both calculators are great options. However, there can only be one clear winner, and that winner is the TI-Nspire CX CAS.

Though the TI-89 is not a bad calculator, it is heavily dated, and it shows in the way that it functions. Aside from its pixelated screen, which does not allow for fit to screen capability, the speed and even internal memory are outdated and do not allow functions to perform at an optimal level.

Though the TI-89 can give the TI-Nspire CX CAS a run for its money, the TI-Nspire CX CAS offers users a large subset of functions and abilities. These include the creation of documents, the ability to solve problems, and even the ability to add games to your calculator.

The TI-Nspire CX CAS is a great calculator to use with a multitude of courses. These include classes like statistics, chemistry, algebra, and calculus. This calculator can take users from high school through to college as well as be used on standardized tests with the exception of the ACT.

Hopefully you enjoyed this TI-Nspire CX CAS review and have found it helpful. Choosing the right calculator is essential to doing well in your math and science courses. Regardless of what anyone says, take your time and select the one that works best for you.
