CFX-9850Gb PLUS

(With Built In Program Library for EA100 Experiments)


C O L O R GRAPHING CALCULATOR




The CFX-9850Gb PLUS Color Graphing calculator shows three distinctive colors that can be used in a variety of ways. This new calculator makes implementing the NCTM standards in your classroom easier than ever and is affordable at about $84 (Educator Price) Casio's Icon Menu makes it easy to find the functions you need. Six function keys select on screen Soft Keys that make the CFX-9850GbPLUS easy to use because all options are displayed on the screen at one time.



The CFX-9850Gb PLUS Television Interface Unit



Allows direct connection from the CFX-9850Gb+ color graphing calculator teaching unit to any television in crisp, clear color. This stand alone unit is the OH-9850 PLUS





Dual Screen capability shows a two graphs, a graph and a zoom or a graph and table on the same display.



A new CONICS feature draws and analyzes standard Conic Sections (Ellipses, Circles, Hyperbolas and Parabolas). Students can trace along the curves, or solve to find points and values of interest like Foci, Asymptotes, Directrix, Tangent, Slope and more. Using the Background feature, students can compare Conics with the graphs of functions drawn in other calculator modes.



The CFX-9850Gb PLUS powerful statistics packages has the ability to build and manipulate up to 36 lists of data. A wide variety of statistical calculations are easily completed on each data list with the touch of a single button. With the PLUS, you can master list-based statistical calculations with both single and double variables. It also performs linear, median-median, quadratic, polynomial, cubic, quartic, logarithmic, exponential, power, logistic, and sinusoidal regressions. The advance statistics include 9 different hypothesis testing and six confidence interval functions.



The powerful dynamic graphing feature allows the opportunity to dynamically see a graph unfold before your eyes. Enter your own equations or use the built in equations. For example, if you use y = mx + b and want to see what happens to the line as the slope is altered from -4 to 4, you set m as your dynamic variable with a range of -4 to 4. Then set your y-intercept (b) to any desired value. Now sit back and watch to show. Great for discovery learning! You have to see this live!

The EA-100 Data Analysis System

The EA-100 Data Analysis System will be able to measure and collect data for temperature, light, motion, sound, force, and pH. Data is collected and stored in real time by sensitive, veneer compatible probes. The data can then be transferred directly into the CFX-9850G or CFX-9850Ga PLUS color graphing calculator, which automatically creates applicable graphs and tables for the collected data.  The 9850GB+ also has a built in library of programs to use for the EA100.
