    I am experiencing the same problem, but when I try cycling through the line types, I'm not seeing any of the line types shown in the manual. Instead, I get an arrow (actually a black right-facing triangle with a dark vertical bar to its right), the black triangle alone, or a black triangle with a "shadow" (looks like a dotted greater-than sign just to the right of the triangle). No regular line, none of the other usual options. One symptom is that a graph with disconnected asymptotes (like 1/(x-2)) will show a connected line between the two asymptotes. I can't think of why it would do this -- anybody seen this behavior before, or know how to fix it?

On a line where you enter the function to graph, highlight the screen to the left of the Y. Press ENTER. Every time you press ENTER, the graph style will change.
Hope it helps.

    Another possibility is that the Transfrm Application is running. It takes over the graphing capabilties from the native OS. You should unload it from memory.

    1. Press [APPS]

    2. Scroll down to reach Transfrm

    3. Select it and press [ENTER]

    4. You get a new screen TRANFRM APP and two options.

    5. Select [1:Uninstall]

    6. Restart your graphing.

Half of my home screen is taken up by the graph application. how do i get the screen back to normal? also everytime i do anything the answer is wrong ex. 5x6=3.0e1 ???

You're in a split-screen mode. To get out of it, press MODE, press down-arrow to get to the line beginning "FULL", use left-arrow to highlight the "FULL", press ENTER, then 2ND [QUIT].

It's giving you the correct answer. 5x6 is 3x10^1, which is 30 in scientific notation. To get out of scientific notation, press MODE, highlight "NORMAL" on the top line, press ENTER 2ND [QUIT].

Cannot get the pulse tone off the line and that prevents from voicemail access and call forwarding HELP!

In guessing that since your lines have defaulted to pulse dialing that you have an older Nortel system such as an 8x24 or a 6x16 system. That being said you'll need to program touch tone dialing on each line.

Programming is done on M7310, M7324 and T7316 sets.
To set up ringing you need to enter programming by pressing the feature key followed by **266344.When prompted to enter the password enter 266344.
the display says A. Configuration
4 top line/feature keys are now used for programming
Press the show key (top right arrow)
the display will say1. trunk/line data
Press the show key (top right arrow) .
the display will say line 001.
Press the show key (top right arrow)
the display trunk data
press the show key (top right arrow) Press the next key 7 times(bottom right arrow) .
The display should say Dial mode: pulse.
Press the Change soft key (below the display).
the display should now say tone. press the heading key (top left arrow) to get back to "trunk/line data" repeat the steps for the remainder of your active lines
press Rls when finished

On the school-provided TI-84 Plus Silver Edition calculators, when one enters a math problem or equation which would take more than one line, the characters wrap to the next line. However, I have just...

You need to change the mode from Math Print to Classic Mode to get the multiple line display. Press Mode to open the correct menu. Use the up/down arrows to make sure that an item in the first line is highlighted (MathPrint or Classic). Use the left/right arrows to select Classic. Press Enter. If you see a line labeled Save, use the down arrow to highlight the line and press Enter again.

This is briefly shown in the manual. See page 9 (page 16 of the PDF) for the menu that applies. The section is labeled Setting the Clock. The rest of the details on changing modes is on page 15 (page 22 of the PDF). Texas Instruments has the manual for the TI-84 Plus Silver Edition in their support section. Start here: . The direct link to the manual is .

I hope this helps.

My TI--84 plus calculator won't display the 7 graph modes, and it won't graph equations simultaneously. What is wrong? I can only get an arrow icon and an arrow-bar icon.

Use the [Y=] entry screen to enter the functions you want to graph. Make sure that the = sign after Y1, Y2 etc. is highlighted (black). If the = sign is not highlighted the corresponding function will not be drawn. You can can up to 10 functions, but what is the point of drawing so many if they overlap?
Anyway, to change the graph style of the curve for a particular function, use arrows to move to the line, then use left arrow to the bit of line that appears to the left of the Y. Highlight the segment an press ENTER. Each time you press ENTER the style changes to another one. Beware of the unconnected bubble style. During the drawing it will show the position of the point being drawn, but at the end, the whole curve, so to speak, evaporates.
As to simultaneous graphs, if it is important to you to have the graphs drawn for all the curves at the same time, you can enforce that by pressing [MODE], and using down arrow to reach the 6th line Sequential Simul. Use the right arrow to highlight Simul and press ENTER.
Whether drawn sequentially or simultaneously, all graphs will be displayed, except for the ones with the unconnected bubble as style.

Hope it helps.
