Texas Instruments Ti 92 Calculator Review
The TI-92 graphing calculator isn’t limited to just numbers like most other models. It features the ability to solve equations and expressions with variables. The equations, expressions and graphs show up on a clear and concise, 20 x 128 pixel display, which is larger than those of most other graphing calculators. In fact, the equations are displayed on the screen just exactly as they are written in a math text book!
Clear, symbolic manipulation aside, the TI-92 also has the ability to solve basic math equations. It is a great choice for statistics, calculus, engineering, geometry and algebra students. Users can hook their device up to the PC via a TI-GRAPHIC LINK accessory. From there, they can download a variety of different apps and upgrade the software when needed. The keyboard is easy to use, and students can type in expressions and equations without difficulty.
One great feature the TI-92 offers is that its history screen can store up to 99 queries and solutions. Students can go back and retrieve up to 99 previous answers for simple administration. This graphing calculator contains about 188K of user-available RAM and 384K of archive data. Altogether, this is more than 500K memory! Obviously, it’s a lot more than most other calculators out on the market.
Here are some of the features of the TI-92 from Texas Instruments:
- Symbolic manipulation
- Differential equations
- Units of measure
- Linear algebra
- 3D rotation
- Contour plots
- Input/Output ports
- Split screen mode
- Compatibility with other TI models
Indeed, this model is a great choice for all math and science students. It can be a bit confusing at first for those who aren’t used to Texas Instrument graphing calculators, but the instruction manual makes it easy to understand. Furthermore, free instruction guides are available online for users to look into. They can connect their TI-92 graphing calculator to the internet to share tips and information with other users.
The split screen mode allows for students to view two applications at the same time. Not only is the LCD display big, it’s also viewable under most lighting conditions. The plots and 3D surfaces are displayed in real time, helping users to visualize expressions in 3D. The TI-92 can be enhanced with powerful apps. They are fully customizable and programmable.
As for the programming, some of the options include dialog boxes, pop up windows, customizable menus and many user defined functions. Users can look through the catalog to find syntax listings for every last command and function! Needless to say, this makes things whole lot easier.
Perhaps the only downside is the price for a new model. The cost for a new TI-92 Plus graphing calculator is at around $200, and the price for a used TI-92 is at around $20. The TI-GRAPHIC LINK accessory is sold separately.
