Selecting the RUN-MATRIX icon will allow you to
perform general computations and arithmetic.
The lkey executes operations. When data is
entered, the lbutton must be pressed to store the
data.
The zkey is used to obtain a fraction bar. To obtain
a mixed number, press zafter inputting the whole
number.
The Okey will power the unit on. To turn the unit
off, press the yellow Lkey, then Okey.
The xkey is a toggle key that will change answers
or entered numbers back and forth from decimal to
fraction form.
The dkey operates like the back arrow on a web
browser; it will take you back one screen each time
you select it. The dkey will not take you to the icon
menu.
The pkey displays every mode the calculator has.
To select a mode, you may $B to the desired icon
and press lor press the number or letter in the
lower right hand corner of the icon.
The function keys allow you to access the tab (soft
key) menus that will come up at the bottom of the
screen. When an uappears above the ukey,
selecting uwill offer more on-screen choices.

Icon Menu Name Description
RUN-MATRIX This icon menu is used for general computations, including absolute value, logs of any base,
summation, derivatives, integrals, and matricies.
STATISTICS
This icon menu is used to perform single-variable (standard deviation) and paired variable
(regression) statistical calculations, to perform tests, to analyze data and to draw statistical
graphs.

graph polar, parametric, x=, and inequality graphs on the same screen.
DYNAMIC GRAPH This icon menu is used to draw multiple versions of a graph by changing the values in a
function.
TABLE This icon menu is used to store functions, to generate a numeric table of different solutions
as the values assigned to the variables in a function change, and to draw graphs.
RECURSION This icon menu is used to store recursive formulas, to generate a numeric table of different
solutions as the values assigned to the variables in a function change, and to draw graphs.
CONICS This icon menu is used to graph parabolas, circles, ellipses, and hyperbolas. You can input a
rectangular or polar coordinate function or a parametric function for graphing.
EQUATION This icon menu is used to solve linear equations with two through six unknowns, and higher-

This section is an overview of the GRAPH Icon and will highlight some basic features of this
mode. To enter the Graph menu, highlight the icon and press lor press 3.
The initial screen is the function/relation editor. Enter a function in Y1 and press lto store it.
To draw the function, press u.
To quickly change your window, you can utilize the Replay arrows. Specic changes can be made
to the viewing window by selecting V-Window (e).
To analyze features of this graph (roots, maximum and minimums, y-intercepts, intersections,
determine coordinates, and integrals), select y(G-Solv).
1. To draw the graph of the function y = 2x2 - 5x - 3 from the Graph editor screen, input the
following:
• 2fs-5f-3lu
You can change the type of graph (r = polar coordinates, parametric functions, x =, and
y-inequalities) by pressing e(TYPE), then selecting the corresponding TYPE button.
