Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

I put my equation into the y= screen and press the graph button at the top right corner and then it exits out of my y= equation screen and just has a 4 ? everytime i press the graph button after that it's like i'm actually hitting the 4 button ? help ?!

Hello,

It seems that wires got crossed. I suggest you reset all RAM by the follwing steps

[2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]

Ram cleared will be displayed on screen. [CLEAR] to go to the home screen.

If that does not solve your problem, reinstall the OS. Post a question on how to install OS, if you want, or read some of the posts on TI83/84/89 about same subject.

If nothing works, I am afraid you will have to repair the calculator.

Hope it helps.

Usually ypu know the equation then graph it. However in doing statistics, it may appear that the curve of best for a scatter plot could be could an exponential. In that case you use the STAT application to enter the x-data in List 1 and the y-data in List 2. When you finish press the f1 key to select Graph1. You should also verify by Pressing F6:set that the graph type is set to scatter, and that List 1 contains the x-data and List 2, the y-data. After you verify that all is in order press the F1: Graph 1 key.

As the graph is displayed you will see several tabs with various regression models. Pan thr tabs to the right to get to F2:EXP. Select it.

The equation is displayed on the next screen. At the bottom of the screen you see two tabs COPY and DRAW. Press f5:Copy to copy the equation in one of the y= functions.

Press Draw and you will see the curve of best fit superposed on the scatter plot points.

in order to give the calculator a function to graph, you will want to enter the y= window by pressing the top left most button on the calculator.
a menu similar to the one above will open, wherein you can enter an equation for the calculator to graph, such as (x^2-2). On the ti-83 itself, you can enter up to 9 equations to be graphed at once. after that, you may want to go to the window menu, where you can set the dimensions of the graphing plane in both the x row and y column. to view the graph, press the top right most button on the device.

hope that helps :)

In all probability, someone used the Transfrm Application before. The problem is that it lingers in memory and has to be unloaded from RAM.

To do so

To do so

- Press the APPS button.
- Scroll Up or down to reach the Transfrm APP.
- Select it and press ENTER.
- In the subsequent screen, press the number that corresponds to the UNINSTALL option.
- Validate the selection by pressing the ENTER button.
- Go back to your Y= Editor and enter up to 10 functions, then press the GRAPH key.
- Graphs should know display correctly.

Press Y= (the first function key on the top row). On the line beginning Y1=, put in the right hand side of the equation: 3 ALPHA [X] - 1

Press GRAPH (the last function key on the top row) and you'll see the graph. If you want to look at different parts of the graph, press WINDOW and change the window settings.

When you press [STAT] and right Arrow to highlight CALC you see two linear regression model [4:LinReg(ax+b)] and [8:LinReg(a +bx)]

If you select [4: ...] the command echoes on main calculator screen as LinReg(ax+b) and a blinking cursor

If you press [ENTER] you will get your equation, a, b, and r^2 if DiagnosticsOn command has been executed before. However you will not be able to see the line of best fit on top of the raw data scatter plot.

To save the equation of best fit in a function variable, ex Y1, you complete the command as follows

LinReg(ax+b) [VARS][=>][Y-VARS][1:Function][1:Y1]

The Y1 variable will appear on main calculator screen, and you have

LinReg(ax+b) Y1

Press [ENTER]

Screen display the equation, its parameter and its correlation coefficients (if so configured).

Press [GRAPH] to draw the line of best fit on top of the scatter plot.

Here are two screen captures to show you the equation and the line of best fit.

As you can see from the value of r^2, and the graph, a linear regression does not seem good.

Hello,

Turn calculator ON. If you do not see several icons press [MENu].

Use arrow to select the [GRAPH] application and press [EXE].

In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.

Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.

At the position of the cursor enter 5 [X, theta,T] key under the [ALPHA]. On the screen appears 5X, complete you equation +2.

Press [EXE] to store function.

If you want to draw other functions, it is time to do so on that screen.

When done press [F6:Draw}.

If the screen does not show a lot of the function, you can use the arrow keys to pan the graph.

You can also press [SHIFT][V-Window] to set the window limits.

Hope it helps.

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.

how to fix window to graph Pythagorean property

Sep 01, 2009 | Texas Instruments TI-83 Plus Calculator

This is probably because you have the stat plot on. You would need to go to y= and then go to the top where it says stat plot 1 and un highlight it if it is highligted. That should fix your problem.

If either error occurs when trying to graph a function (not a STAT PLOT), the error can be corrected by turning off the STAT PLOTS. The following steps will turn the STAT PLOTS off, allowing the graph of the function to be displayed.• Press [2nd] [Y=] to access the STAT PLOTS menu.

• Select 4: PlotsOff.

• Press [ENTER].

• Try graphing a function like y = x^4-3x^3+6x-1

• Select 4: PlotsOff.

• Press [ENTER].

• Try graphing a function like y = x^4-3x^3+6x-1
