Casio FX-9750GII Review

With its icon-based menu, the CASIO FX-9750GII is an easy-to-use graph calculator. It offers most basic and some advanced functions that make it suitable for middle school and high school math, finance and science courses, but it doesn't feature CAS or natural display capabilities. The CAS, or computer algebra system, allows the graphing calculator to manipulate mathematical expressions symbolically and return symbolic expressions as answers. This allows you to input the equation as it would be seen on paper.

It's also lacking when it comes to 3D graphing and geometric equations, compared to more advanced models. It does have a shutdown feature that saves battery life. It also has AP statistics functions, making it useful for statistics students, especially those in advanced high school classes.

Because it lacks CAS software, this graphing calculator is permitted for use on the ACT, SAT, PSAT/NMSQT exams and AP tests. It includes many basic and advanced graphing functions, like polar graphing, complex numbers, recursive sequences and hyperbolic functions. It doesn't offer geometric, pie chart or inflection-point capabilities, however. Its functions make it suitable for courses like algebra, calculus, pre-calculus, statistics, business, physics and chemistry.

While it doesn't offer a color display, the calculus graphing calculator does feature an LCD display and multi-colored buttons that make inputting and viewing information easy. It also has prior entry recall so you can retrace steps.

The graph calculator features a fast processor for quick calculations, but it only has 62KB of ROM, making storing equations, formulas and apps difficult. Software upgrades are not available electronically, but the unit comes with a USB cable for connecting the calculator to other devices, like your computer or a projector.

Four AAA batteries come with this graphing device, but they are not rechargeable. To save on power, it does have an auto power-off feature that shuts down the graphing calculator after a certain period of non-use.

Permitted on all standardized and AP tests, the Casio FX-9750GII offers many graphing functions students need for middle school or high school courses in math, science and business. It is lacking in some advanced functions, however, and doesn't have a lot of storage space.
