When graphing the calculator only allows me to graph on function. When typing in a new function the first function that was highlighted became unhighlighted and only the new function is highlighted now.

Hi Lexy,
Chances are, your calculator has a program called "Transfrm" on it that is preventing the calculator from graphing more than one function at a time. Luckily this is easily remedied.

1) Turn calculator on and press the "APPS" key.
2) Scroll down (towards the bottom of the list) and find the "Transfrm" program.
3) With the program highlighted, press the "Enter" key.
4) Highlight the "Uninstall" option and press "Enter".

Once the program is uninstalled, the graphing function of the calculator should be working correctly, allowing you to graph more than one function at a time.

Hope this helps :-)

The fact that you are asking how to graph makes believe that you solved the problem about 'invalid dimension' . I am glad that worked for you.

This should help you setup your calculator to do graphing.

1. Prepare calculator for graphing Turn StatPlotsOff to avoid errors:

Press [2nd][STATPLOT][4:PlotsOff][ENTER].


2. Setup Graph type

• Press [MODE] key.
• In Mode set up screen, make set the angle unit (if you are drawing trigonometric functions)..
• Use the arrows to move cursor to 3rd line to highlight degree or radian and press [ENTER]. The important thing is that you be aware of the unit so that you do not get unexpected results.
  
• On same screen, verify that Func is highlighted. If you are drawing PARametric plots, POLar plots or SEQuence plots, you highlight the relevant item in the list
  
• If it is not, use arrow to highlight Func and press [ENTER] to validate.
• Do not worry if you do not have exactly the same screen as in the screen picture (We may have different OS Versions)
  

3. Entering the functions to draw (assuming you want to draw y= functions)

• Press [Y=] to enter function editor.
• Type in a function
  
• Press [ENTER] at the end of each function.
• Before pressing [GRAPH], make sure that all the = signs that define the functions to be graphed are highlighted white on black. If one is not highlighted, use arrow to move cursor on the sign and press [ENTER].
• In the screen capture 4 functions are slated to be drawn.
  

4. Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)

• Select the graph style: The small piece of line to the left of a Y that defines a function is the style.
  
• Move cursor on it and press [ENTER] .
  
• Each [ENTER] (on same line) selects another style.
• On the next screen you have all the styles available on the calculator.
• Do not select the bubble on line 6: It is for animations. It will not leave a trace at the end of the plot.
  

5. Drawing the Graphs

• Press [GRAPH] to see the graphs.
• If one of them is missing, verify that its = is still highlighted, then use the [WINDOW] to set the Window dimensions,
• Here are the dimensions of the standard window
  

6. ZOOMING
You can also press [ZOOM] to adjust.



The selection 6:ZStandard sets the dimensions as on the screen Titled Window (above).

Here is the link to the manual.
Here is a short tutorial to get you started.
First thing to do before any new type of graphing problem
1. Turn StatPlots OFF : press [2nd][STATPLOT][4:PlotsOff] [ENTER]

Second thing: Clear the statistical lists
2. Press [2nd][0][PGRM] DownArrow to point to ClrAllLists.
3.Press [ENTER][ENTER]

Third thing : Configure the graph type to be FUNCTION graph
4. Press [MODE]. If FUNC (on fourth line) is highlighted. Press [Y=] and start entering the functions.
5. If FUNC is not highlighted, use Down arrow till 4th line, highlight FUNC and press [ENTER]. Press Press [Y=] and start entering the functions.

Fourth thing: Enter function and select them for graphing
1. As you start entering the function Y1=, notice that the = sign becomes highlighted. Press [ENTER] when Y1 is typed in. Make sure the = sign for Y1 remains highlighted as cursor moves to Y2=.
2. Keep entering the functions and verifying that their = signs remain highlighted as cursor moves to another equation.
3. When finished press [ENTER]
4. Look at the graph style for each function: it is a bit of line to the left of each Y. Here is a picture of all the 7 styles.



To set a graph style, highlight the style to the left of the Y, and press [ENTER]. Each time you press [ENTER] you see a new style, in the order shown on picture.
Avoid the style of Y6, it is bubble, and as such will burst and disappear once graph is finished. Avoid also the triangular ones (for Y3 and Y4) they will shade areas of the graph, and may hide other functions.

Fifth thing: Graph Functions.
1. You can press [GRAPH] to see your graphs.
2. If one curve is missing (and you have not set its style to be rhe bubble), it may be due to the Window dimensions.

Sixth Thing: Set Window dimensions and Zoom.
1. Press [ZOOM][6:ZStandard] to use standard window dimensions.
2. If curve still missing, Press [ZOOM][3:Zoom Out] to zoom out so that you may be able to see a bigger range for the functions.
3. If necessary press [WINDOW] and set the Xmin, Xmax, Ymin,Ymax to values of your own.



Dimensions must obey the conditions: Xmin < Xmax, and Ymin < Ymax.

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.

You can skip the next paragraph if you want

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 Transfm application. Select it and press [ENTER]. If that application was running you will see a new screen that tells you
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.

Hope that helps.

Hello,
Once you enter an equation the corresponding equal sign is highlighted by default. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted. If one is not highlighted, move the cursor on it and press ENTER.

Once all the = signs for all the functions ypu want to draw are highlighted permanently, press the [GRAPH] key.
Depending on the functions ane the window dimensions certain graphs may not show up and one can Zoom out or adjust the window.

If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER]
Command PlotsOff echoes on main screen. Press [ENTER], screen displays Done.

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 shouild make it a habit to clear the RAM every time you start a new type of problem.

Hope it helps.
