When it is time for you to put an expression in absolute value, press the OPTN key, then F5/Num, then F1/Abs. Open parenthesis, input expression, then close parenthesis.
For fractions, use the key with the symbol a b/c.
A little friendly advice, please do invest some of your time reading the manual. Most Casio graphing calculators work the same way. What you learn on one, works on another.
In Run/Mat screen, press the OPTN key followed by F6, the F3:Prob. The nPr and nCr tab are accessible. Type n then the relevant tab, followed by the r-number.
It is a calculator and prqactically every button is a MATH button. It
depends on what MATH you intend to do. Put the calculator in Run/Mat
screen then press the OPTN key. You will see several tabs. Press the
function key under a TAB and explore what is offered. Go through all the
keys (F6 also) and see what the new tabs do. In general it is most helpful to read the manual that shipped with the calculator.
Sorry but you cannot do that. This is not a graphing calculator. However you can generate a table of values for your function (MODE TABLE) and use it to graph the curve by hand (pencil and paper).
If you need a Casio graphing calculator, one of the cheaper ones is the Casio FX-9750GII. Equivalent Texas Instruments calculators are the TI83PLUS/TI84PLUS.
Hey it is. Okay, so start with a equation: say, y = -(1 |x|).
Now type y = -(1 , then press the [OPTN] button, next to the shift. Next press the [NUM] button or F5. The first menu button should be Abs or absolute value. When your done it should look like this.
y = -(1 Abs (x)) then graph it.
If you have to restrict your selection to one or the other the Casio wins "hands tied behind its back". If you need convincing read on.
Advantages of Casio Newer technology About half the price About twice the Ram Uses iconic menus Most screens have tab/menus: No need to scroll. Conic graphic embedded in OS, not need for an extra application Dynamic graphing embedded in OS, no need for an extra application Has a reset button Several types of statistical graphs that do not exit on TI83 (pie chart) Ability to select the integration algorithm Better screen resolution.
