Question about Casio FX-9750GPlus Calculator

# Graphing inequalities How do you graph inequalities on the casio? Example: y= x-2 if x>-2 and on the same graph graphing a second equation y=x-1 if x<4 I've found the sequence of commands (if condition is supposted to be first) but I haven't found a key sequence that works under the regular graph mode (calculus class) Thanks

While the graph function menu is on the display press the F3 button to display the graph you want to do. Then press the function key that corresponds to the graph that you want. If you have the manual it explains it on page 117. Kind of hard to explain it here when you can't type the buttons. LOL

### How to turn off shading when graphing inequalities.

The solution set of a linear inequality in two variables (x,y) is one half of the Cartesian plane. The half-plane may or may not contain the boundary line defined by the = sign. Thus it is expected that the calculator shades the relevant half-plane. If you are dealing with nonlinear inequalities the calculator shades inside or outside the curve.
When drawing multiple inequalities the Casio offers you the possibility to shade the regions where ALL conditions (ALL inequalities) are simultaneously satisfied. The other option is OR.
If you are not interested in the shading do not draw inequalities, draw equations (with =).

### Inputting inequality signs in equations on Y= graphing menu.

Choose one of the inequality type graphs by pressing F3 Type. Press F6 for the arrow on the right, you will get the other types For example press F1 to select the Y greater than type graph. Notice that on the top line Graph Func: Y>. From now on all the graphs you will draw will be Y> some function in X.
Start entering the function. As you start the screen will show Y1> Enter the function for example sin(X^2). Use the X, theta, T to input the X variable. Press the EXE key to complete the function line. The screen will look like on the following screen grab Press the F6 key Draw to get your graph and the shaded region, as on the following picture:  Jun 22, 2017 | Casio FX-9750GII Graphing Calculator

### Syntax error for graphs

That hardly seems possible. Try graphing the function y=x.
There are a few ways to draw curves on this calculator
1. Drawing functions
• Type is y=f(X), the [X,theta, T] key enters X when pressed • Type POLAR r=f(theta), key [X,theta, T] enters theta w. pressed. • Type PARAMETRIC, requires an X=f(T) and Y=g(T) functions • Inequality graphing. You can also draw some functional inequalities such as y> 2X^2-3
• Dynamic graphing (graphs where some parameter may be changing)
Drawing Relations
There are some other relation you can draw X=, X>, X< , and the drawing of general conics. I hope that the foregoing remarks help you sort out the problem you are having. If they fail to do that, I suggest that you read the manual that shipped with your Prizm.

### I cannot get the calculator to graph more than one line. I've tried highlighting teh equals sign and hitting entor to make it dark but it will only highlight one equation at a time.

One of the applications Inequalz or Transfrm is still loaded in memory and it controls the graphing capabilities of the calculator. To restore control to the naative OS, proceed as follows.
Press the APPS button.
Scroll dowwn or Up to find Inequalz.
Select it and press ENTER.
A message is displayed sayin Inequal Running.
Select 2:Quit Inequal.

If the message you get is
APP CONFICT.
or Conflicting Apps
Reset the RAM to kick the applications out of memory

### Im trying to graph a parametric equation and whenever the equation has an exponent/power in it the calculator says Syn error so i know how to graph x=2 cos T, y=2 sin T and similar equations without a...

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).
As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

### How do you graph inequalitys on the graphing calculator

Press the MENU key
Select 5:Graph and press EXE
In the Y= editor window, press F3:TYPE
Press F6 to access other graph types.
Select the inequality symbol you want and enter the right member of the inequality, then press EXE.
You are returned to the Y= screen.
When done entering your expressions to graph, press F6 Draw. Jan 22, 2011 | Casio FX9750GII Graphic Calculator

### Can i solve an equation of second degree(like X^2+2X+1) with Casio FX-7400G Plus ? If so how?

Sorry but the calculator does not have a solving routine. You can however use the graphing capabilities of the Casio FX-7400GPLUS to solve an equation f(X)=0.
1. Graph the function Y=f(X)
2. Use the trace function to locate the point(s) where the function vanishes (has value Zero)
See the screen capture for an example.

If you were hoping that this calculator would be able to factorize polynomials for your, sorry my friend it cannot.  May 15, 2010 | Casio FX-7400G Plus Calculator

### I cant graph more than one equation at a time, it only allows me to graph one Y value at a time.

A) Before drawing function Y1=f(X), R1=F(Theta), (X1=f(T0, Y1=f(T))
you should turn the statistical plots OFF.
To turn statistical plots off
1. Press [2nd][Y=] to open the (STAT PLOT) menu.
2. Select [4:PlotsOff] and
3. Press [ENTER].
4. Calculator displays Done
5. Restart your graphs.
6. Adjust the window dimensions if necessary or use the ZOOM function to have all graphs displayed.

B) If you cannot draw more than one function

Usually as soon as you start entering an expression in the Y= editor screen, the = sign is highlighted to ensure the drawing of a function. However, if you have previously used the Transfm application to draw dynamic graphs, it takes over the graphing functionalities from the native OS and you can only draw a single graph.
The reason is that dynamic graphing needs one or two parameters that can be changed during the graphing process and the graph redrawn with a new value of a parameter, and you end up with a family of curves differing one from the other by the values of one parameters. But since the calculator has space for 10 graphs at most, only one function can be highlighted.

To make a long story short, you must Uninstall the Transfrm application from memory. The procedure will not erase it, just kick it out of memory.

1. Press the [Apps] key.
2. Scroll down or up to reach the Transfmapplication.
3. Select it and press [ENTER].
4. If that application was running you will see a new screen that tells you some thing like
• Transfrm App
• 1:Uninstall
• 2:Continue

Press1:Uninstall.
Graphing functionalities will revert to the native OS

Another potential culprit is the Inequalz App. You recognoze that Inequalz is runnibg if the [ Y=] editor screen shows tabs at the bottom To uninstall it, do as for the Transfm and select the option that will unload it from memory.
1. Press [Apps]
2. Select [ : Inequalz]
3. Screen displays INEQUAL RUNNING
• [1:Continue]
• [2:Quit Inequal]
Press [2:Quit Inequal]

### How would you enter the following equation to graph on a TI-84 Plus Silver Edition calculator? 2 <= t <= 9

Hello,
To enter the inequation you split it into two inequalities Graph is as follows Use [2nd][CATALOG] to access the relaional operators less than or equal, greater than or equal, and the operator AND.
To access the inequality signs scroll upwards from abs( to reach the bottom of the catalog.
Note: You can use t as variable only in parametric graphs. Use x.
Hope it helps.
