That comparison would be featured in a Product
Some of the notable graphing calculators available, besides the TI-84 Plus, are the Casio fx-9750GII and HP Prime Graphing Calculator.
First of all, the Casio fx-9750GII is cheaper than the TI-84 Plus, plus has a very high-resolution display. It has built-in USB ports for connecting it to another computer for transferring data and boasts a memory of 62 KB. But in the advanced features, the Casio model isn’t as far advanced as the TI-84 Plus, which is capable of making custom programs.
The HP Prime Graphing Calculator is another of the premium clan calculators that can stand along with TI-84 Plus. It has a full-colored multi-touch display and a rechargeable battery that can last up to a month. The HP Prime also has a 32 MB built-in memory capacity, which is a lot more than the TI-84 Plus. It is however, more pricey than the TI-84 Plus and thus much may not be needed by the users who do not require such advanced features.
Pros and cons of TI-84 Plus
Pros:
Advanced features of custom program and app creation
Large built-in memory capacity
High-resolution backlight screen
Rechargeable battery
Automatic shut-off for battery conservation
Cons:
Higher price point compared to some other graphing calculators
Some even very complex functions take time to learn and master
It may have more machine than what some users would need
Summary
In a nutshell, the Eric Armin 70845 TI-84 Plus Graphing Calculator is one of the best for students, teachers, and professionals interested in high-quality, advanced calculators for their work. Although the price is generally higher than that of its competitors in the market, the very advanced features and capabilities make it worth the investment. However, users who do not need such advanced capabilities may get equally satisfactory answers through a lower-priced alternative like Casio fx-9750GII.
