Question about Texas Instruments TI-84 Plus Calculator

Ad

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

- Press [2nd][Y=] to open the (STAT PLOT) menu.
- Select [4:PlotsOff] and
- Press [ENTER].
- Calculator displays Done
- Restart your graphs.
- 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.

- Press the [Apps] key.
- Scroll down or up to reach the
Transfmapplication.
- Select it and press [ENTER].
- 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.

- Press [Apps]
- Select [ : Inequalz]
- Screen displays INEQUAL RUNNING

- [1:Continue]
- [2:Quit Inequal]
- 3:About]

If you have the equation of the line (of best fit), enter a value of x in the equation to get the value of y. Similarly, if you have a target value of y, enter it in the equation and solve for the value of x. That's about it.

At first in Y editor type **Y1=2*cosx** and for example **y2=[5*exp(-x)]-5** and then graphing it. Set **RAD** mode of course. See captured images

function or run a user-defined program that references a local variable that is not

initialized (assigned a value). You have to type

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.

how to fix window to graph Pythagorean property

Sep 01, 2009 | Texas Instruments TI-83 Plus Calculator

A circle is not a function and cannot be graphed in the regular y=screen. You can graph a circle in parametric mode.

To graph a circle in the regular y= screen, you have to graph it in 2 lines on the y= screen. I assume you've solved for y and gotten a square root equation. Remember a square root can be positive or negative. In line 1 of y= screen graph what you've been graphing and then graph the same equation in line 2 but with a negative in front of the equation. You'll get something that looks like an oval since the calculator screen is rectanglular. To make it look more circular (both parts aren't going to connect), press zoom and then select #5 (square).

go to apps menu, go to transform app. click uninstall and go to y= screnn and should be a slash on the left and you should be able to graph more than one equation.

The first solution will allow you to watch your
calculator graph two equations simultaneously rather than finishing one
before graphing the next; it won't solve the problem of having the
calculator unselect one equation when you select a second. To fix
that problem, try the following:

In order to select additional graphs, the Transformation Graphing App will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling the App does not erase it from the calculator, it disables it from interfering with the normal graphing modes. Below are the steps to successfully uninstall the App.
