BRIEF DESCRIPTION OF CASIO
This document covers a very approximate and preliminary description of the
mathematical capabilities of the Casio Prism graphing
calculator and some comments on its similarities to the Casio CFX-9850GB Plus.
More information may be added as I become more familiar with
This brief review is not intended as a
comprehensive or complete review
the prism calculator, but is merely a preliminary description to
some idea of the capability of the calculator. This review is written from
the perspective of a college math teacher and, like the other
parts of this
website, has no information that would be useful to gamers or
people interested in the calculator as an entertainment device.
I do not
own a Casio
Prism calculator. So the information included in this review has been obtained from
various places on the Internet and from
occasional use of the
Casio CFX-9850GB Plus.
Date of Composition: 12/10/10 Release Date: Not released.
Last Revision Date: 1/27/11
General Comments: As one
might expect, this is not a new calculator started from scratch, but is very
similar in some respects to the
The user interface
is icon driven as is the Casio CFX-9850GB Plus, and the categories of most of the
icons are similar to
the Casio CFX-9850GB Plus.
The Prism has eighteen
icons, whereas the Casio CFX-9850GB Plus has fifteen.
In fact, the keyboard
is very similar to the
CFX-9850GB Plus, except
for some additions on the numbers part of the keyboard. These additional
functions are as follows:
Capture, Clip, Paste, Ins, Undo, Catalog, Format,
Some of the functions that have been added
that were not on the
are as follows: eActivity,
Spreadsheet, E-Con2, Geometry. It also has copy and paste features. It
has a Math
Input/Output mode which the Casio CFX-9850GB Plus
does not have.
Picture Plot lets you plot points that represent
coordinates on a photograph, drawing, or other graphic and perform various types
of analyses. For example,
a regression analysis on a curve in an illustration could be performed
A computer will recognize the calculator when the
calculator is plugged into a USB port, and screen capture can be accomplished
without additional third-
I should not fail to mention that the fantastic advancement of this calculator
is the amount of memory and the display resolution and number of colors
that it has. I will not attempt to describe the display and the features that
are available with this display. You can best see this at the following
Impressive Features: The
calculator has 65,000 colors, a high resolution 384 x216 display and 16 MB of
Some Functions of Interest:
||Graphing display includes graphing on actual landscapes.
||Full capability on matrices.
||Full range of statistical functions such as different
distributions, different tests, an 1- and two variable statistics.
||This has a 26-colunm x 999-line spreadsheet. You can
also do statistical operations using the spreadsheet.
||Similar to older versions with enhanced resolution and
||Full range of table functions
||This is used to graph conics.
||This mode is used to analyze and draw geometric figures.
||Will give the values of first and second derivatives at
points on a graph.
||Will give the value of the definite integral between points
on a curve or between curves.
Although I do have not been able to confirm this, I suspect that it has the
options of Gauss
and Simpson's the same as the
|Some thing it will not do:
|Give the antiderivative
|Give the derivative in algebraic form
|Solve differential equations
