Question about Texas Instruments TI-83 Plus Calculator

We where working in class with years and numbers we had to change the numbers on the window Xmin, Xmax,Xscl, exct. and know I am trying to graph something and it will not give me the correct answer.

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.

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.

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.

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.

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.

Press [WINDOW] key.

You can try to reset the calculator: In so doing the default configuration is restored. If that works for your graphs why fiddle with the setting?

Ok to reset calculator (do not worry I will tell you how to change window dimension):

Press [2nd][+] to access the (MEM)ory management.

Press [7:Reset][2:Defaults] [2:Reset]

The window dimension will be restored.

To change dimensions

In main calculator screen press the [WINDOW] function key

Enter the value of Xmin. If negative use the change sign key (-) under key 3

Enter Xmax value. Make sure that Xmin is less than Xmax.

Leave the Xscale at 1

Enter Ymin. If negative use the change (-) key

You can leave the Yscale at 1, Xres at 1.

You can change the DeltaX but if you take too small a value your graphs will take long to be drawn.

If you ever get a problem, just press the [ZOOM] function key and select [6:ZStandard] it will restore the default dimensions.

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.

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.

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.

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.

More than likely, you've put in a number in the xmin or xmax that is not correct. Example....you put in an xmin of 10 and an xmax of -10 which would be backwards. This could also happen in the ymin or y max.

The easiest way to fix this is to press zoom 6 which wil get you back to the default graph of xmin of -10, xmax of 10 and ymin of -10 and y max of 10.

If you can't see your graph on this screen and need to change the window, just be sure the number in the min for both x & y is smaller than the number in the max. You change your window size by pressing the window button.
