Question about Texas Instruments TI-83 Plus Silver Edition Calculator

1 Answer

I can't graph more than one equation in the y= area of my Ti 84+

This has to do with some kind of setting that i can't fix.. when i press the y= button, all the icons to the left of the y1, y2, y3, etc. are arrows pointing right, but can be changed to double arrows, an arrow with a bar on the right... for the equation to be graphed, the "=" sign must be highlighted, and it will only let me do one at a time. what can i do to fix the settings so that I can graph multiple equations at the same time?

Hello,
The marking that so puzzle you define the type of line (or dots) to represent the graphs. Enter as many functions as there are Y variables.
After entering a function press [ENTER] to jump to the next one.
When finished entering all functions press GRAPH. If you want graphs drawn one after the other, in MODE highlight Sequential (6th line) and press ENTER. If you want graphs drawn simultaneously, in MODE (6th line) highlight Simul and press ENTER. Press 2ND QUIT to return to previous screen . Execute graph again.
Hope itr helps.

    Here are a few screens to illustrate the styles (line and dotted lines) produce. By highlighting the piece of (style) line to the left of a Y and repeatedly pressing enter you cycle through all the styles available. The last one selescted will be the style of the actual graph of the function .




    All the functions for which the = sign is highlighted and remains highled when cursor is moved another location will be drawn.

    Now a change of graph style is applied to one function. The segment at the ledt of the Y for the cosine is dotted.


    The cosine is represented with a dotted curve

    ADDENDUM

    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. To Uninstall it, do as for the
    Transfm and select the option that will unload it from memory.

How to set a ti-84 to graph both sides of the equation separately on the same coordinate system.


If I'm understanding you correctly, you want to graph something like

5x+3=9

If this is correct, graph 5x+3 in the y1 line and 9 in the y2 line. To find the solution, you will press 2nd, then trace the intersection and hit enter 3 times. This will get the solution you need for the equation.

If this is not what you are wanting to do, you need to be try again and elaborate more.

My TI-84 PLUS calculator wont show the graph after i type in an equation. please help!


You need to fix your graph so that it shows the correct y-axis and x-axis.
It works best if you press the zoom button and then scroll to find the ZoomFit option.
Then the graph should show up.

TI 84 plus calculator refuses to graph more than one function


Hello,
Please, read the following, even if you already know some of its contents.
  1. Once you enter an equation, the corresponding equal sign is highlighted by default.
  2. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted.
  3. If one is not highlighted, move the cursor on it and press ENTER.
  4. If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER].
  5. Command PlotsOff echoes on main screen.
  6. Press [ENTER], screen displays Done.
  7. Restart the graphing procedure.
  8. If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.
You should make it a habit to clear the RAM every time you start a new type of problem.

Hope it helps.

Entering inequalities into TI-84 to graph


I think you should get a Texas Instruments calculator and push the 'y=' button then put the equation like '2x+4' in the y1 area. You can put the X by using the variable botton. I hope my english makes sense I am not a native speaker.

Graphing


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.
  • Press [APPS] key
  • Select Transfrm from the menu
  • Press 1:Uninstall

Can't select multiple equations to graph at the same time.


On the TI-84 there is an application called Transfrm. When active it prevents you from graphing multiple functions at the same time. To fix this, select Transfrm fom the APPS menu (it was at the bottom of mine) and select 1:Uninstall. That should fix the issue
