Not found message when trying to get the minium on the graph

Do you have Zonealarm? This may be a message from it. See... http://www.techsupportforum.com/forums/f217/no-valid-installation-configuration-found-650441.html
If the message is from Zonealarm, and you have your license key, I would try uninstalling and then reinstalling it.

Open the window configuration ans set Ymin to -10. You can also access the ZOOM function and select Zoom Standard.

Before graphing deactivate the statistical plots: Press [2nd][Y=] to access the (STAT PLOTS) configuration screen and press [4:PlotsOff][ENTER]

To draw polar graph, make sure in MODE, POL is highlighted.
Make sure that the angle unit is set to RADIAN
If you want the angle unit to be in degrees you must open the WINDOW editor to modify the values of Theta max to a significant value: 30, 45, 60, 90, 120, 180, 360, otherwise the calculator will take the default value 6.28 (2*PI) in degrees

If the message appears when you try to graph functions deactivate the statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)
Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.

If the message appears in another context, it sure would help knowing the context of the error.

In home folder (main calculator screen) press [Diamond][F2:Window]] to access Window configuration screen.
Press [F1] ( not mecessary now because the F1 page is open by default). In the F1 page of configuration screen set Xmin=-10,
Xmax=10
Ymin=-10
Ymax=10
Xscale=1.
Yscale=1.

OR
Press [Diamond][F2:Window][F2][6:ZoomStd] (Zoom Standard) to set all values as above.

If a graph is active (axes displayed, or part of a curve is showing) press [F2:Zoom][6:ZoomStd]

Well, that depends.
The real question is: What are you trying to graph?
If you want to graph function y= f(x), then why are you using the Inequalz application, which draws inequations. The ShadeRes(olution) is a system variable needed by the Inequalz application. You can use the default 3 value or change the value to 4, 5, 6, 7, 8.

When Inequalz runs it takes over the graphing functionalities and impose some changes in the calculator configuration, and one of those changes is the appearance of the ShadeRes variable in the Window configuration screen. Also, once the Inequalz App is launched, it remains in memory until you kick it out of Ram, or clear the RAM

My hunch is that you should not be running Inequalz, so I will show you how to unload it of memory so that you can draw your "regular" graphs.

UNLOADING INEQUALZ

1. Press the [APPS] key
2. The screen INEQUAL RUNNING is displayed with the following selections
   

• 1:Continue
• 2:Quit Inequal
• 3:About

You press [2:Quit Inequal] to unload the Application from the memory.
Return to your regular graphing and a Window configuration screen without the ShadeRes variable.

TO SUM UP
If you are drawing inequations with Inequalz, you cannot get rid of the ShadeRes variable. You can only give it another acceptable value.
If you are drawing "regular" function graphs, unload Inequalz from memory.

Hello,
You must have done some statistical calculations. This type of calculations activates the statistical plots. The resulting configuration conflicts with the normal graph configuration.
Before drawing function graphs, you must turn off the statplots:
Press [2nd][Y=] to access (STATPLOT)
Press [4:PlotsOff][ENTER][ENTER] Calculator displays Done.

Then you press [2nd][0] to access the (CATALOG) of commands. Then [PGRM] to enter the letter [C]. Cursor jumps to the first command that starts with the letter c (omitting the Greek symbols). From there, scroll a bit to highlight [ClrAllLists] and press [ENTER][ENTER]. After clearing the lists the calculator displays Done.

You should be able to draw your graphs.
If that does not work, just reset the Ram as described below.
Press [2nd][+] to access (MEM)
Press [7:Reset][1:All Ram][2:Reset].
Press [CLEAR] to erase the Ram Cleared message.

Press [Y=] and enter your functions. Press [ENTER] at the end of each function. Make sure each [=] after Y1, Y2, remains highlighted after the cursor moves to some other location.

Hope it helps.

Hello,
If you do not get an error message, then the graph is out of range. Try to zoom out, or play with the window dimensions.
Hope it helps.

I think you are saying that when you graph, you get the message "invalid dim"

If you are trying to graph from the y= screen it may me that you have one of the plots on. If this is the case, look at the top of the y= screen. If plot 1, plot 2 or plot 3 has darkened box around it, the plot is on and you need to turn it off. Move your cursor on top of the one that is highlighted and press enter. You should now have the plot turned off and should be able to graph from the y= screen.

Another way to do this is to press 2nd key, plus key and then 7, and then 1 and then 2. This will reset your ram.

Hope this helps

Hello,
I am not sure I understand but if you are talking about the ZoomStandard graph window, you access the configuration as follows. Press MENU, Scroll to highlight the [RUN] icon and press [EXE].
Press [SHIFT] [F3:V-Window]. At the bottom of the screen you have the different options . Press [F3:STD].
Hope it helps.
