Hello,
Kick the program out of memory and archive it if you want to free RAM.
Reset Memory defaults. Graph parameters will be restored and you will be able to graph.
Hope it helps.

Could not find the main class: Program will exit


Are you trying to access a program that you downloaded?
Are you trying to program something?

This is an error that is encountered when a program is started but the system cannot find the main class (The first step to starting the program which controls the whole flow of the program)

If it is something you downloaded from a rookie developer, or something you programmed yourself take a look at your main function, it is probably declared improperly. Google the specific language you are using to see how it is supposed to be declared.

If it is a mainstream something you are trying to install and run something somewhere corrupted. Try to re-download and reinstall. If that doesn't work it is possible something in your registry is corrupted... unlikely, but possible.

If you don't have version 2.53MP of the operating system on the TI-84 Plus Silver Edition, you can download it from
http://education.ti.com/educationportal/sites/US/productDetail/us_os_84plus.html

You can check the version of the operating system by pressing 2ND [MEM] 1. The OS version number is on the second line.

Once you're running OS 2.53MP, press MODE to enter the mode editor. Press down-arrow repeatedly to get to the second page. On the top line, highlight MATHPRINT. Press ENTER to select it, then press 2ND [QUIT] to exit the mode editor.

Graphing syntax error


To draw graphs.
  1. Turn calculator ON (isn't that obvious?)
  2. If you see no icons, press [MENU]
  3. Use arrow to move focus on GRAPH and press [EXE]
  4. By default, the graph type is Y=
  5. Enter your equation on line Y1=, use the [X,theta,T] key to enter the X-variable
  6. Press [EXE] when finished entering a function.
  7. Enter other functions if you want.
  8. When done, press [F6:Draw].
  9. If you do not see a big portion of the curve you can press [SHIFT] [F2:Zoom] and select [F5:Auto]
I am enclosing screen captures. The screens you see may not look exactly as on the FX-9750G, but all menu commands you have to execute are accessed by the same key sequences.

7. During installation of security sites


Possible Solutions:

4. If it is obsolete, uninstall it and reinstall it with the latest one

5. Check For any 3rd party tool that may interfere with the unpacking of software

6. If so un install it.

How do you plot two liner equations on a ti-84?


I use one of the graphing APPS or do through a program. I have a users manual for TI 84 silver Edition that shows you how to archive\ unarchive to run programs here at this site. Usually, I tell people to just forget about the programs and use the simple concepts so, that they could operate their calculator better. But, if you notice in those program are actually more powerful than the programs you get on the web, because I wrote them to be flawless, or I only used programs that I knew would not clash and were very well written. Won't y1=(2/5)x-(11/5) and -3x+8 work?

y1=(2/5)x-(11/5) and -3x+8

Problem using graphing on my casio


This calculator has so many options you can change, that it is possible one of them has been altered. Try pressing the master reset button at the back to re-set the calculator. Note that you will lose all your programs and data, so first copy out anything important. Also, set the xmin and xmax parameters to a higher value. To plot a sign wave, try xmin=-720, xmax=720, step=1, ymin=-1, ymax=1, step=.1 The step value won't change the appearance of the graph, just make it more chunky or fine. Use the equation y=sin x. This should draw a sign wave showing 4 complete waves. PS when you enter the X in the equations, you are pressing the X,0,T button, the one under the alpha key, aren't you? If you enter X using the x alpha key, it won't work. Also, to plot y=, make sure you change the func type parameter in the Set Up menu to y=. Hope this helps.
