Question about Texas Instruments TI-84 Plus Calculator

# Hello, if i type all my numbers in L1, with these variabels xmin=1.5, xmax=26.5, xscl=25, ymin=0, ymax=25, yscl=1, en xres=1 then i do 'graph' and i have only one little point on my screen, This is not normal, can you help me? thx adelina

That is normal behavior because you specified the scale factor along the x axis to be 25. Well there is only space for just one point between 1.5 and 26 when the jump is equal to 25.
Please reset your calculator to its default configuration and avoid to play with the setting if you have not read about what its value means.
One easy way for you to recover a normal behavior is to press the ZOOM button and select ZoomSTD or if you are doing statistics select ZOOM DATA

### How do you change the interval for a arc cos

I'm not sure of the question, but to plot arccos set mode to: graph='function' and angle to 'degrees' (for example). Go to WINDOW and set xmin=-1, xmax=1, xscl=0.1, ymin=0, ymax=180, yscl=50, and xres=1. Press GRAPH. You will get a plot of arccos from -1 to 1.

### How do i know what numbers to use for my xmin, xmax and xscl and ymin, ymax, and yscl, when setting my graphing window.

Usually you won't set them at all, they'll be set automatically by your zoom settings. Xscl and yscl set where the lines will appear on the x and y axes (if x and y scale are set to 1, there will be a line on the axis every 1 unit). Xmin/Xmax and Ymin/Ymax represent the visible size of your window, if you want to see different part of your graph, you can change these settings, or use the zoom button.

### Today i was trying to graph y=2x+23, but when ever i would press graph it would pop up window variables domain. What do i do to fix this?

Your ranges for your window settings are more, or less out of bounds with the equation y=2x+23, that you entered.
Press the [green diamond], and the [F2] keys to bring up the graphing coordinates. Enter the following values to fix the graphing coordinates. Starting at the top, xmin= -8, xmax= 8, xscl=1, ymin=0, ymax=40, yscl=1, xres=2. Now, press the [green diamond], and the [F3] keys, and the graph should display.

### How do I change the dimensions on my ti-84?

You probably mean window dimensions. If that be the case
Press [WINDOW] key.
Use cursor to scroll down the lines. Change Xmin, Xmax,Ymin, Ymax, Xscl, Yscl. Make sure that Xmin is less than Xmax, and Ymin is less than Ymax.

### No matter what I type into Y= it says err: Window Range

Press the [Zoom] function key and select [6:ZStandard]. The default window dimensions will be restored: to Xmin=-10, Xmax=10, Xscl=1. Ymin=-10, Ymax=10, Yscl=1, Xres=3, DeltaX=0.2127659574

And don't just type anything you want into Y=, make sure that it respects the syntax of the functions, and that you do not set Xmin larger than Xmax, and/or Ymin larger than Ymax.
If any of the dimensions is negative, use the (-) change sign key before the value.

The difference between Xmax and Xmin must be much larger than the DeltaX.

To check the good working order of your calculator always try with a linear function that passes through the origin (0,0). A good example is Y1=X or Y1=2X. If the graph works for these simple functions and does draw with your function then the problem is with your function and not the calculator.

Actually to enable us to offer competent advice you should always say what you were trying to do (the function to draw, the dimension you set). An all encompassing statement such as "No matter what I type" is not helpful at all. All that is left for us to do is guess.

### All trig-based graphs give me weird results on my TI-89 Titanium. Taking y=sin(x) for instance, I get a clean diagonal line through the point (0,0), almost resembling the graph y=x with window xmin = -10...

You have your angular mode set to degrees. Ten degrees is about 0.17 radians, and for small x: sin(x) is nearly equal to x. Thus, sin(x) from -10 to 10 is indeed nearly a straight diagonal line.

Press MODE, then scroll down to "Angle" to change the angular mode.

### ERR: Window Range

Press ZOOM and select Zoom standard (ZoomStd).
Alternatively, press the WINDOW key to access the window range setup
Set Xmin=-10
Xmax=10
Ymin=-10
Ymax=10
These are the standard dimensions of the window.
You can change the dimensions as long as Xmin is less then Xmax, and Ymin is less than Ymax. Do not make Xres close to Xmax-Xmin.

### I don't have a problem with my calculator but I need to know on how to put in values for graphing example Xmin=, Xmax=, etc.

Hello,
Xmin must be less than Xmax; Ymin must be less than Ymax. If your X variable takes only positive values you can set Xmin=0; if you want to graph y=X^2, you know that all y-values are going to be positive, so there is no need to waste screen real estate by putting Ymin negative.
It is like taking a picture with a camera. You point the viwefinder where the action is.
My suggestion is to set the default values Xmin=-10, Xmax=10, Ymin=-10, Ymax=10. Then look at the graph and locate the part that interests you more and focus on it by zooming in. Your knowledge of the general behavior of the function will help you determine what is worth looking at.
Hope it helps.

### What numbers should the window key have

Hello,
Xmin is the smallest value of variable X: by default it is -10.
Xmax is the largest value of variable X: by default it is 10.
Ymin is the smallest value of Y default is -10.
Ymax is the largest value of Y default is 10.
You set these values according to the area of the graph you want to see.
If X is always positive, you can set Xmin=0.
If function values are laways positive, eg y=x^2, Ymin=0.
Xscl =1 by default. There will be a tick mark on the X-axis for each X integer.
YScal=1: there will be a tick mark for each integer value of y. If you want tick marks every 0.5 you set Yscal=0.5
Xres=1. Calculator calculates y values say at X, X+1, X+2, etc.
Hope it helps.

### Err: no sign chng

When you get the sign change error it is either that you have mixed up the left bound and the right bound or that you are marking the left and the right bound both above the x-axis or both below the x-axis. That's why you get the sign change error. Your range values must have different signs.
