To restore the default Window dimensions, press the [ZOOM] key and select the option [ZoomStd] (Zoom standard). When in Zoom Standard, the window dimensions are

Xmin=-10.
Xmax=10.
Ymin=-10.
Ymax=10.

You can set Window dimensions by pressing [Window] and enter meaningful values that maximize the view. In any event Xmin must be Less than Xmax
Ymin must be Less than Ymax.
You will have to test different values to optimize the view. Knowing something about the function will help you determine where the interesting behavior is.

How do I graph a simple equation, without getting an error 07 message? y=-1.5x+3


Error 07 Syntax
Means you made a typing error while entering the equation. Using the minus sign instead of the negation sign (change sign) (-), can produce a syntax error. Maybe you need to explicitly type the multiplication sign
y= (-) 1.5*x +3
Try entering it as 3 - 1.5*x

Cannot graph two equations together, & trig graphs are not correct.


At first in Y editor type Y1=2*cosx and for example y2=[5*exp(-x)]-5 and then graphing it. Set RAD mode of course. See captured images

I am trying to graph any possible equation and I get undefiend varialbe for any kind of equation as simple as x=7. It will always show as undefiend varialbe for any equation. I don't know why it does this.


Undefined variable error message displays when you evaluate a user-defined
function or run a user-defined program that references a local variable that is not
initialized (assigned a value). You have to type LineVert 7 and then graph function x=7. See captured image

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.

Graphing Problems


In home folder (main calculator screen) press [Diamond][F2:Window]] to access Window configuration screen.
Press [F1] ( not mecessary now because the F1 page is open by default). In the F1 page of configuration screen set Xmin=-10,
Xmax=10
Ymin=-10
Ymax=10
Xscale=1.
Yscale=1.

OR
Press [Diamond][F2:Window][F2][6:ZoomStd] (Zoom Standard) to set all values as above.

If a graph is active (axes displayed, or part of a curve is showing) press [F2:Zoom][6:ZoomStd]

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.

How do you set up window range?


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

Graph feature not working on my TI-83 Plus


Simple:

Hit this sequence:

"ZOOM" "0"

That is for the "Zoom Fit" option. The calculator does not like the window you have for the equation you've given it. With this option, it will automatically give you the best fit in the window for the equation!
