TheO key will power the unit on.To turn the unit off, press the yellow

Lkey, thenOkey.

Thelkey executes operations.When data is entered, thelbutton

must be pressed to store the data.

Thedkey operates like the backarrow on a web browser; it will takeyou back one screen each time youselect it. Thedkey will not take

you to the icon menu.

Selecting the RUN iconwill allow you to performgeneral computations and

arithmetic.

Thepkey displays every mode thecalculator has. To select a mode,

you may$Bto the desired iconand presslor press the number or

letter in the lower right hand cornerof the icon.

The

x

key is a toggle key that willchange answers or entered numbersback and fourth from decimal to

fraction form.

Thezkey is used to obtain afraction bar. To obtain a mixednumber, presszafter inputtingthe whole number.

The function keys allow you toaccess the tab (soft key) menus that

will come up at the bottom of the

screen. When an appears abovetheukey, selectinguwill offermore on-screen choices.

GRAPHVarious icon (Run, Table, Dynamic, Recursion & Conics) will allow you to graph or analyzethe graphs of given information. This section is an overview of the GRAPH Icon and will

highlight some basic features of this mode.

The initial screen allows immediate input of function set equal to zero. You may begin

inputting data into Y1:and presslto store. To draw your function, selectu.

You can change the type of graph (r = polar coordinate, parametric functions, x =, and x-and y-inequalities) by select the corresponding function button and then press the$tobegin inputting information.

1. To draw the graph of the function from the Icon Menu system, input

the following:

3x5x2y 2

32fs-5f-3l

To analyze features of this graph (roots, maximum and minimums, y-intercepts,

intersections, determine coordinates, and integrals) selectyG-Solve).

2. q(Root):

Note: The left-most root will always display first. Select$to display the nextroot.

3. e(Minimum):

Note: As long as the x-value of your vertex is in the viewable domain; you do notneed to see the vertex to calculate the minimum value. However, you canchange the viewing window by selectingein the graph window. You canalso change the windowmanually by using the!$BN.

4. r(y-intercept):

5. q(y-calculation): What is the value of y when x is 5 ?

6. w(x-calculation): What is the value (s) of x when y is 1?

7. e(integral): Determine the integral value at (0,3) for the function .3x5x21Y 2

TABLEThe section is an overview of the TABLE Icon. To select this icon, you may highlight it and

presslor press5.

The initial screen allows immediate input of functions that are set equal to 0. To changethe typeof expression to be entered, selectwforpolar coordinates,efor parametric

functions orrtochange a previously entered function to an inequality.

1. To see a table for the function 4x3

2y , highlight Y1:and input the following

2z3f-4lu

2. The default setting for tables is: X starts at 1, ends at 5, and increases by incrementsof. You change this by pressingdorq(FORM) to return to the initial screenand thenselecty(SET).

3. However, you can manually enter a number anywhere in the x-column of the tableandpresslto see the corresponding y-value (including fractions, decimals, even

). You caninsert and delete rows in this view by pressinge(ROW).

4. From the table view screen, you can pressy(G-CON) to see a linear graph oru(G-PLT) to see a plot graph for the function you entered.

STATISTICSThis section is an overview of the STAT icon; it will highlight just a few of the features forsingle-variable data and paired-variable data. To select this icon, you may highlight it and

presslor press2.

The initial List Editor Screen that allows input of statistical data and performs numerous

statistical calculations. To input a list of single-variable data, highlight the first cell underList 1 and enter eachnumber followed byl.

1. For this example, input this set of data:

1, 0.5, 1.2, 4, -1, 1, 3, 5, 6, 3.4

2. From this screen you display various graphs depending on whether you single or

paired-variable data (scatter-plot, line, normal probability, histogram, median box,mean box, normal distribution, broken line, and regression: linear, quadratic, cubic,quartic, logarithmic, exponential, power, sinusoidal and logistic).

3. The initial default graph is a scatter-plot. To change the type of graph you wouldlike to use, pressq(GRPH), thenu(SET),Nto Graph Type:, for this set of data,we will make a histogram, pressu, and thenqfor histogram.

4. Pressdto take you back to your list of data and selectq(GPH1)and thenltoseeyour graph.

5. The following screen shots show what one-variable calculations can be obtained bypressingq.

6. To delete this set of data, pressduntilyou return to the initial List Editor screen.Selectufor more options, arrow up until List 1 is highlighted, selectr(Del-A),thenq.

7. For paired variable data, use the following:

List 1: 0.5, 1.2, 2.4, 4.0, 5.2List 2: -2.1, 0.3, 1.5, 2.0, 2.4

Enter List 1 first, and then$to begin entering List 2.

8. To see a scatter-plot of these data, you can go through and change back GPH 1using theprocess above, or selectw(GPH 2) from the List Editor screen whosedefault is also a scatter-plot.

9. From the scatter-plot screen, pressingqwillshow all the calculation that can beobtainedfrom this set of data.

10. To calculate linear regression, selectwfrom the first set ofoptionsand then pressqfor form.baxy

11. From this screen, you selecty(COPY) to copy and then paste the equation intothe initial graph screen or selectu(DRAW) to show the linear regression.

EQUATIONThis section is an overview of the EQUATION Icon. To select this icon, highlight it and

presslor press8.

The initial Equation Editor screen has three modes to choose from, Simultaneous,Polynomial, and Solver; this section will give an overview of each mode.

The Simultaneous mode allows you to solve simultaneous linear equations with two to sixunknowns.

1. Solve the following system of equations:

7zy4x5

1z3y6x1z2yx4

Pressqto select the Simultaneous mode and presswfor three unknowns. Thecalculator will display a matrix where the coefficients and constants can be enteredin to as long as each equation is in standard form. To enter this system of equations(already in standard form) input the following:

4l1ln2ln1l 1l6l3l1l n5l4l1ln7l

There are four options at the bottom of the screen, pressq(SOLV). The solution

to thissystem is (1, -1, 2).

In the last screen, Lft and Rgt represent the values of the left and right sides that havecalculated using the solution; this is the calculators way of checking the solution.

You can also enter a formula, assign values and solve for specific variable using the Solverfunction of the Equation Editor.

6. Find the radius (to the nearest hundredth) of sphere, whose volume is 3705.97 cm3.

To enter the formula3

4V r3input the following in to the calculator:

qBa2L.4z3Lca6^3l

Note: Selectingqwill take you back to the previous screen where you can edit and re-

solve the previous equation or begin a new problem.



15/15

CONICSThis section is an overview of the CONICS Icon. To select this icon, you may highlight it

and presslor simply press7.

The initial screen allows you to choose from various conic functions, including rectangular,polar or parametric form. You may use theBNto select the equation of the function inaccordance with the type of graph you want to draw. Once you have chosen the conic

function that you would like to graph, you will need to enter the coefficients of thefunction and then press DRAWu.

1. To view the graph of the conic: y , select the form

from the Conics formula menu.

3x5x2 2 CBXAXY 2

In the Conics modes, when you pressyG-Solv), although you are still graphing aparabola like in the graphing section, notice how the vocabulary and options havechanged.

2. For example, you can now examine the line of symmetry for this parabola and theequation of that line will be displayed.

You can continue to analyze different areas of this graph and the line of symmetrywill still be displayed.
