Question about Texas Instruments TI-84 Plus Calculator

Ad

Hello,

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.

Is it somehow preventing you from graphing, or are you simply not getting the graph you expect?

Most likely you have the angular mode set wrong. You probably want it set to radians. Press MODE, move to the third line, highlight RADIAN, press ENTER, then 2ND [QUIT].

If it's not the angular mode, please reply to this post and give an example or two.

At first in Y editor type **Y1=2*cosx** and for example **y2=[5*exp(-x)]-5** and then graphing it. Set **RAD** mode of course. See captured images

You have to use **Y Editor** to define functions on the both sides of the equation and then graph it. Finally option is **F5: Intersection**.

See captured images for equation**5x+10=-2x-7**, **y1=5x+10**, **y2=-2x-7** and **x=-17/7**

See captured images for equation

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.

Some time or other she played with the Transfrm Application. It remains in memory and takes over the graphing capabilities of the native OS. It must be kicked out of memory.

- Press [APPS]
- Use Up or Down arrows (Up is faster) to get to the bottom of the APPS list.
- Locate [:Transfrm], highlight it and press [ENTER]
- In subsequent screen, select the [UNINSTALL] option.
- Go back to the [Y=] screen and enter or edit your functions.
- Press [GRAPH] when finished entering the functions.

Press the Y= key. Move to the equation in question, then press left-arrow repeatedly until the cursor is at the far end of the line. Press ENTER repeatedly to cycle through the different graph styles. The default is the four dots in a diagonal line from upper-left to lower-right.

Hi,

What you call a megaphone is a bit of graph style that the calculator can use to display graphs. There are 7 styles. To select a style, open the Y= editor. On the same line where you typed in an equation, use the left arrow to move the cursor on the graph style piece. Highlight and press ENTER. Each time you press ENTER, the style changes, so you can cycle through all the available ones. Be careful with the bubble style, it will not leave a graph. It will evaporate.

Whether you draw the graphs simultaneously or sequentially amounts to the same thing**at the end.** Both graphs will be present on the same sceen (except the bubble).

What you should make sure of is that the equal signs of both functions (Y1=, and Y2=) remain highlighted as cursor moves to another location. Usually, an equal sign becomes highlighted as soon as you start enbtering the relevant function. If you cannot keep both highlighted, I suggest you reset the calculator RAM.

**To reset Ram**

Press [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER] . Press [CLEAR] to clear the "Ram Cleared" message.

If for some reason you do not want to clear the Ram, you must turn statplots of.

**To turn StatPlots Off**

Press [2nd] [Y=] (STATPLOT). Select [4:PoltsOff][ENTER][ENTER].

That should work.

Hope it helps.

Don't forget to rate the solution and don't be stingy: 4 thumbs up won't leave you any the poorer.

Hello,

The marking that so puzzle you define the type of line (or dots) to represent the graphs. Enter as many functions as there are Y variables.

After entering a function press [ENTER] to jump to the next one.

When finished entering all functions press GRAPH. If you want graphs drawn one after the other, in MODE highlight Sequential (6th line) and press ENTER. If you want graphs drawn simultaneously, in MODE (6th line) highlight Simul and press ENTER. Press 2ND QUIT to return to previous screen . Execute graph again.

Hope itr helps.

The calculator only displays from -10 to 10 on the x and y axes, and both of your lines are outside of that range. However, it is easy to change that.

1. Hit the gray "WINDOW" button that is directly under the screen

2. Change "Xmax" to 150

3. Change "Ymax" to 200

Remember to change both of those values back to 10 when you are done with this problem!

Here's how to graph it:

1. Hit the "Y=" button

2. Enter your first equation after Y1, and your second equation after Y2

3. Look over both the equations to make sure you typed them correctly

4. Hit the "GRAPH" button

5. If you don't see the intersection you will need to adjust Xmax and Ymax again

6. Hit Hit "2ND" and the "TRACE" to bring up the "CALC" menu

7. Scroll down to "intersect" and hit enter

8. Hit enter 3 times (You use the first and second curve options when you have more than 2 lines)

9. It should display the coordinates at the bottom

10. I got (76, 142.1) for the intersection

Thanks for asking this question! I used to do this a much harder way, but while I was calculating the answer to your question I hit a wrong button and accidentally found this method!

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.
