Graphing calculator has been around for quite a long time now. First available for public in 1985 by Casio, now there are so many of them in the market. They comes with the same Graphing calculator name but the level or capabilities are vary depend on the unit itself. In today TI 89 vs TI 92 article, we will compare both items to give you more information regarding what you can expect from them, so you can choose more wisely.

Even though it is not as slick as Nspire CAS, the menu still very intuitive and ahead of its time. It lets you perform basic math, calculus, algebra, graphs, matrices, creating animation, statistical functions, graphing 3-D rotations as well as plotting contours. The graphic functions will covers the basic function graphing as well as parametric graphing, polar graphing, sequence, 3-D, and differential-equation.
To add into the capability list, TI 89 also able to do symbolic manipulation, constants, and measurements units as well as statistics and data plots, etc. You may connect your calculator to other calculators or with a computer when you need to upgrade it to the newer software. It comes with 188 KB RAM and 2,7 MB flash memory to store programs, functions, and data.
About TI 92
TI 92 is a line of calculators by Texas Instrument that comes in a unique look with a Qwerty key layout that makes it somehow different than many other calculators out there. This graphing calculator was initially launched in 1995 and have several versions after. Because of this different design, people are calling it as computer rather than calculator and taken from Wikipedia, you can’t use it when taking test like SAT or AP Exams. Even though it was over a decade old, it works just a great as modern calculator if the appearance doesn’t bother you.

As it has been mentioned earlier, TI 92 used a Qwerty design and making the calculator looks like a combination of calculator and laptop. The item measures at 5 x 8.5 x 1.5 inches and weigh around 1.3 pounds that making it twice as big as regular graphing calculators. It has a wide display at 128 x 240 pixels that allows you to view information in a split-screen options. It looks tough covered in light black plastic material and many keys that arranged to be user friendly.
TI 92 Capabilities
When it was first launched in 1955, this calculator is the first Texas Instrument that comes with computer algebra system, which means those people at that time who own this calculator is able to solve and receive answers in fraction form, radical form or even make the calculator solve one variable in terms of another. It is indeed ahead of its time. It also a cutting edge for giving the users the ability to graph in 3 dimensions.
When the company start to plant flash memory to their calculators in late 90s, they released the second version of this model, the TI 92+ that not only has a memory to upgrade the operating system but also comes with improved screen that offer better contrast and easier to read than the original model. Today you may not able to find the original model anymore, but you may still get your hand on the + model.
Just like you can expect from a powerful calculator, it comes with built-in applications such as Text editor, Statistics, Matrix calculations, and programming. The Text editor is able to store and retrieve information while the computer like features let you do cut, copy, paste, and find. Since it able to split the screen, you can view two application at once simultaneously.
Now, let’s compare TI 89 with TI 92. As you may already know, these two are very similar and since the company put memory in TI92+ you can upgrade the operating system, so now the model is in par with TI 89. Both of them basically have the same abilities, but TI 89 comes in smaller size, which makes it more favorable. TI 92 also can’t be used in SAT or AP Exams unlike the TI 82.
