Is CAS worth the extra money?

If you are looking to pursue a career in one of the STEM fields and require a calculator that can grow with you, the CX CAS is a great option. However, you will need to be mindful of the tests you will use the calculator to take.

If you are up for the potential challenge of learning how to use the calculator, this is a great option. The calculator is also great for calculus and the varying equation types you will use within the course. CAS is excellent if you are looking to do factoring and have obvious answers with variables included.

If you are in lower-level math, then CAS is not an option and would not be worth the money. However, if you are looking to grow mathematically and at some point, take a more advanced math course, it is worth it. CAS would also not be recommended as it allows the calculator to do the majority of the work for you in lower-level courses like algebra II.

CAS is meant for tasks which are tedious to perform by hand. Once you become familiar with using calculators which have a CAS, they are an incredibly huge help.

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

Both calculators boast a thinner design than most of the other Texas Instruments calculators, most notably the TI-89. This ensures that the calculator is portable and lightweight.

Both calculators also boast a rechargeable lithium-ion battery. These batteries typically last upwards of 3 years with normal usage. Both calculators have also been designed to have a look and feel of a typical computer screen, along with having a full keyboard on the bottom.

On both the TI-Nspire CX and the TI-Nspire CX CAS items can be grouped by type. These types include documents or applications. The document-based interface allows for the creation of documents and ensures things are organized. When altering items inside of a specific document, that document is the only place where the change takes place. If you are looking to open another application, another document will need to be opened. This can be tricky to get used to at first but will soon become second nature for users.

Though the color quality on each calculator is noticeably different, both items have a 3.2-inch color backlit display with a resolution of 320×240 pixels. The calculators include much of the same hardware, including the keyboard, cursor, and trackball.

Another similarity that these calculators possess is that both have a padded screen. This padding means that you will not crack or break your screen on the first drop. Though you should not be throwing your calculator across the room, accidents happen.

If you are looking to do programming on either of the TI-Nspires, you will need to use either the Lua or TI-Nspire BASIC programming language. Programming on the TI-Nspire is not easy as previous versions of Texas Instruments devices as it is isolated within documents. To some, the process to create a program may be tedious and cumbersome. Programs cannot be accessed from any other document aside from the one that it was built in. This, in turn, limits the number of features available to you and limits the ways the program can be accessed.

Performance is not an issue with either device. Both can perform calculations quickly and without lag. Both calculators are also allowed on the Math AP, PSAT, and the SAT exam. They can also be used within a multitude of courses due to their diverse range of functions.

What are the Differences Between the TI-Nspire CX CAS and TI-Nspire CX?

Though there are not many physical differences, one is the overall color scheme. The CX CAS appears much darker than the CX. This includes some of the buttons as well as the casing. The CX boasts lighter colors with grey buttons, and the directional pad glows with a bright blue color.

However, the main difference between the TI-Nspire CX CAS and TI-INspire CX remains that the TI-Nspire comes equipped with a Computer Algebra System. This means that the TI-INspire CX will not be able to complete the same functions and equations. This includes the ability to solve an equation by simply typing solve. This is something that only the CX CAS can do. Though both calculators boast similar functionality, only the TI-Nspire CX can be used on the SAT, ACT, PSAT, IB exams and the NMSQT. There are some limitations on the CX CAS calculator. These include not being able to work in the z or s domain as well as performing Laplace and inverse Laplace functions.

However, one thing that sets the CX apart is that the CAS can be loaded onto it. Being that this is the more affordable option, many users have found loopholes for accessing the CAS functionality.

Rather than paying the extra money for the TI-Nspire CX CAS, users have opted to use the TI-Nspire CX for the exams which prohibit the use of the CAS. After completing their exams, they can simply load it on the calculator. In theory, this allows you to get two calculators for the price of one.

Things to Consider When Deciding the TI-Nspire CX CAS and TI-Nspire CX

What courses will the calculator be used for?
