Question about Texas Instruments TI-89 Calculator

You know when you're setting the parameters for the windows to graph. You can go with the pre sets ala trig, standard, you can zoom in and out, all that stuff.

But when you hit 2nd, then F2 for window, and it lets you personally input the values, I can do all but xres, all the way at the bottom. It's fuzzed out, similiar to the way after hitting F5 on the home screen, all the other "F"'s get fuzzed out.

Go to the graph app (diamond + f3)

to the graph apps settings (f1 , then 9: Format)

turn off discontinuity detection

go to the window setupt (diamond + f2)

change xres to 2.0

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.

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 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 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.

Alternatively, press the WINDOW key to access the window range setup

Set Xmin=-10

Press the Y= key to invoke the Y= editor. Enter in your equation.

Press the WINDOW key to set the window parameters.

Press the GRAPH key to have the calculator graph the equation.

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.

or press ZOOM, option 6 (ZStandard). That instantly resets the window range.

This calculator has so many options you can change, that it is possible one of them has been altered. Try pressing the master reset button at the back to re-set the calculator. Note that you will lose all your programs and data, so first copy out anything important. Also, set the xmin and xmax parameters to a higher value. To plot a sign wave, try xmin=-720, xmax=720, step=1, ymin=-1, ymax=1, step=.1 The step value won't change the appearance of the graph, just make it more chunky or fine. Use the equation y=sin x. This should draw a sign wave showing 4 complete waves. PS when you enter the X in the equations, you are pressing the X,0,T button, the one under the alpha key, aren't you? If you enter X using the x alpha key, it won't work. Also, to plot y=, make sure you change the func type parameter in the Set Up menu to y=. Hope this helps.

You must press 2nd then "zoom", then go down to axes, and turn them on. Now your graph will work again.

I can't input any value on xres. I can put a number on everything else i.e. xmin, xmax, etc. How do I fix this??

It's grayed out...what can I do?
