    hi
    sry
    i found a solution somewhere else
    but thank you

  • jmb1510 Sep 20, 2007

    it was to go to APPS and run the program INEQUALZ
    it took me a couple of tries, but eventually it ended up working
    i dont remember exactly how it worked when i ran it, but just keep going back to that if u still can't graph

The symbol on the left of the Ysub1,2,etc. determines what type of graph it is. move the cursor to the left of Ysub1,2,etc. and hit enter

Add a graph .
In Documents Toolbox, select 3: Graph/Entry Edit
Unfold the menu and select Equation (not function). Enter your equation.
For the 3D part, I am afraid you will have to read the manual.

When I try to enter a simple equation and graph it, I get error 07 message instead of graph.


Error 07 Syntax
Means you made a typing error while entering the equation. Using the minus sign instead of the negation sign (change sign) (-), can produce a syntax error. Maybe you need to explicitly type the multiplication sign
y= (-) 1.5*x +3
Try entering it as 3 - 1.5*x

The calculator doesnt graph two equation on the graph


The Transfrm application for dynamic geometry is probably active in memory. You must purge it from RAM
  1. Press APPS
  2. Scroll Up or Down (Up is faster) to find Transfm.
  3. Select it and press ENTER
  4. Press the number corresponding to the option Uninstall.
  5. Once the APP is kicked out of memory you will be able to draw multiple functions.

My calculator will only graph one graph at a time.


This is simple... Back up all RAM, (press second+, then 2, then 1, press enter to back up something if backed up it will have a star by it) Then clear your RAM (pull out your batteries while the calc is still on or press second+, then 7, then 1)
Hope this helps!

How to graph linear equation in two variables


I am not quite sure what you are asking...

(1) if asking for graphing y= -2/3x+2, then press [diamond] [F1: Y=] type in .2/3x +2, see graph by [diamond][graph]

(2) if asking for graphing y= -2/3x+a, where a=3x, then first archive a=3x in Home screen by [home], type 3x [sto] a, then go back to y= menu, and type -2/3x+a in Y1

(3) if asking for graphing an equation that is dependent on 2 variables at the same time, use x-y-z axis (aka, change mode to graphing 3-D by [mode]graph [5:3D]) then enter desired equation in y= menu using Z function in terms of x and y aka z(x,y)= ...)

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
