Hi,

A 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

Good luck!

SOURCE: Plotting Points

you can reset all variables, without losing all your programs. you can hit 2nd>Mem(plus symbol)>reset>All ram Then verify that you wish to do so... It should reset to a working condition... If it doesn't then you may need to lose your programs in order to get your calc to a working condition.

SOURCE: TI 84 will not graph multiple functions simultaneously

Turn off transformers. Go to apps and go all the way down until you reach transformers then hit enter. Then a menu should appear and hit uninstall that should fix it.

SOURCE: How do I use stat plot to graph a set of points?

Hello,

1.Press [MODE], scroll to set **Func**tion graphing mode.

2.Press [STAT] [5:SetUpEditor], command is pasted in home screen. Press [ENTER]. Screen displays Done. This clears old values in lists

3. Press [STAT][1:Edit] to enter data.

Press [ENTER] after each number. Cursor moves to next row. After finishing the data of Listt L1, use arrow right and UP to the head of list L2. Enter the values in list L2. Press Enter after last element.

4. Press [Y=] to display Y= editor. Clear function Y1 and all functions or remove highlight from the = in Y2, Y3, etc.

5.Press [2nd][STATPLOT]1 to select 1:Plot1

The blinking cursor on ON means graph will be drawn. Type chosen is Scatter plot. Mark chosen is a dot.

Press [ZOOM][9:ZoomStat]

If you think that the curve look like a straight line you can try to do a linear regression.

Press [STAT] Arrow right to highlight [CALC]

Select [4: LinReg(ax+b)]

LinReg(ax+b) echoes on run screen. Press [2nd] L1 Press comma, Press [2nd] L2 press comma Press [VARS] Arrow right to select [Y:VARs][1:Function] [ENTER][1:Y1]

ENTER

That is the equation for the linear regression. As you see eqaution has been saved in Y1. Press [GRAPH] to get the data and the regression curve drawn on same graph.

Hope it helps.

SOURCE: plotting graphs

usually as soon as you start entering an expression in the Y= editor screen, the = sign is highlighted to ensure the drawing of a function. However, if you have previously used the Transfm application to draw dynamic graphs, it takes over the graphing functionalities from the native OS and you can only draw a single graph.

The reason is that dynamic graphing needs one or two parameters that can be changed during the graphing process and the graph redrawn with a new value of a parameter, and you end up with a family of curves differing one from the other by the values of one parameters. But since the calculator has space for 10 graphs at most, only one function can be highlighted.

To make a long story short, you must uninstall the Transfrm application from memory. The procedure will not erase it, just kick it out of memory.

Press the [Apps] key. Scroll down or up to reach the Transfm application. Select it and press [ENTER]. If that application was running you will see a new screen that tells you some t

Transfrm App

1:Uninstall

2:Continue

Press1:Uninstall.

Graphing functionalities will revert to the native OS

Another potential culprit is the Inequalz App. To uninstall it, do as for the Transfm and select the option that will unload it from memory.

That means one (or more) of the variables you have in your function is not defined. Check to make sure you didn't misspell any variable name. Also, check to make sure you didn't run two variable names together. "ab" is the variable ab, not a times b.

Two, since only one straight line exists that goes through the same two points.

Alternatively, you could define a straight line with one point and a slope.

You cannot have a scatter plot with just **one variable.** You need values in L1 and values in L2. If you have only one set of values you can do **1-var statistics** and plot a histogram (x-value vs. frequency).

As you can see this function have zero values in the points -2, -1 and 4

The fx-115ES is not a graphics calculator so it will not display graphs on its screen. You can use it to make graphs by calculating the points and plotting them on graph paper.

You must deactivate the Statistical plots.

Press [STAT].

In list that is displayed delect [4:PlotsOff] and press [ENTER]

Go to [Y=] editor to enter functions or press [GRAPH] if functions already entered.

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

If you're doing a stat plot, you're plotting a discrete set of points. The calculator doesn't interpolate between the data points.

If you want to graph a quadratic equation, then do so. Enter it in as a Y= equation and plot it as such. This will not only connect the points (unless you tell it not to), but will also allow you to do things like trace.

This error show up when you are graphing out of the plot menu. If you are not graphing data points from list menu, you need to turn the plots off. In the y= screen, you will see the words plot 1, plot 2, etc across the top of the screen. If one of the plots is highlighted (black box over the words), you need to turn it off. This can be done by arrowing up and highlighting the box and pressing enter. When you arrow back down, the plot should be off and you will be able to enter an equation in the y= lines and graph.

If you are graphing from the plot menu, this error lets you know that one of the lists you are graphing is longer than the other.

Another way to fix the problem is to reset the calculator by pressing 2nd button then plus sign then 7 then 1 then 2. This will reset the calculator however if you are graphing from lists, your data will be erased. Hope this helps.

Press STAT, go to Edit, then enter x values in L1 and y values in L2 (other lists can be used too, but these are the default ones).

Next, go to STAT PLOT, pick a plot, turn it on, select the type, data lists (x and y should be L! and L2 already; if not, change them), and mark type.

Finally, hit graph. You may need to adjust window settings to see all of the points. If you get a DIM MISMATCH error, check to make sure that there are the same number of entries in each list, and that only the plots that you are using are turned on.
