CASIO FX-9860GIISD ADVANCED GRAPHIC CALC fx-9860GII Series calculators come with the same eActivity capabilities that originally appeared on the ClassPad 330. Now teachers as well as students can create their own problems and study materials. Students get the opportunity to learn at their own pace for more efficient study both at school and at home. eActivity is a great motivator for learning and understanding. • 61 KB RAM - 1.5 MB Flash ROM. 4 AAA Batteries Required, Best with Polaroid AAA Batteries. • Display: 64 x 128 pixel, monochrome w/ Backlight • Solve Integral/Probability function • Probability function in Run Mat Application - Integral Graphing • Dimension (H x B x T): 184 x 91,5 x 21,2 mm 👉🏻 High-resolution LCD The large 64 × 128-dot display of the fx-9860GII Series high-resolution LCD produces formulas, graphs and graphics that are sharper, clearer, and easier to read. 👉🏻 High-speed CPU A high-performance, high-speed CPU gives fx-9860GII Series calculators processing speeds that are three to five time faster than other brand calculators in their class. Processes and plots encountered in complex calculations and graphics are handled with ease, for enhanced operational efficiency and learning as well. 👉🏻 Large-capacity 1.5MB Flash Memory An ample 1.5MB of Flash Memory capacity allows worry-free downloading and storage of data and applications. 👉🏻 Out-of-the-box USB Operations A USB cable, unit-to-unit cable and Program-Link Software all are included with the calculator, so high-speed data communication with a computer as well as unit-to-unit data and program transfers can be performed virtually out of the box. 👉🏻 SD Memory Card Slot (SD model only) The fx-9860GII SD is equipped with an SD memory card slot for easy data transfers. 👉🏻 Spreadsheet A multi-function spreadsheet with built-in graphing capabilities is a valuable tool for table calculation lesson exercises. 👉🏻 E-CON2 E-CON2 provides total control over the optional EA-200 Data Analyzer. It makes it possible to measure changes in temperature, sound, or speed using the EA-200 without any troublesome settings or program input. 👉🏻 Pre-installed Software Pre-installed add-in software comes installed on the calculator when you purchase it. You can use such software as-is, or you can delete it to free up memory. 👉🏻 Downloadable Software The Physium add-in provides instant access to the periodic table of elements, whose data can be used in calculations. Often-use elements and atomic symbols can be stored for quick and easy recall whenever you need them. 👉🏻 Probability Normal distribution, student's t-distribution, and other often-used statistical calculations are provided in function format for easier practical application. 👉🏻 Inequality Graphing New support for graphing the inequality of an x=Constant graph and x=f ( y) graph allows study of the area for which the x-range is defined.
