SOURCE: ERR: Window Range

Press ZOOM and select Zoom standard (ZoomStd).
Alternatively, press the WINDOW key to access the window range setup
Set Xmin=-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.

SOURCE: How to plot a graph on TI-83 plus texas calculator?

Prepare calculator to graph

Turn StatPlotsOff to avoid errors:
Press [2nd][STATPLOT][4:PlotsOff][ENTER].

Setup Graph type

  • Press [MODE] key.
  • In Mode set up screen, make sure that the angle unit is the degree.
  • Use the arrows to move cursor to 3rd line to highlight {degree} and press [ENTER]
  • On same screen, verify that Func is highlighted.
  • If it is not, use arrow to highlight Func and press [ENTER] to validate.
  • Do not worry if you do not have exactly the same screen as in the screen picture (We may have different OS Versions)

Entering the functions to draw.
  • Press [Y=] to enter function editor.
  • Type in a function
  • Press [ENTER] at the end of each function.
  • Before pressing [GRAPH], make sure that all the = signs that define the functions to be graphed are highlighted white on black. If one is not highlighted, use arrow to move cursor on the sign and press [ENTER].
  • In the screen capture 4 functions are slated to be drawn.

Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)

  • Select the graph style: The small piece of line to the left of a Y that defines a function is the style.
  • Move cursor on it and press [ENTER] .
  • Each [ENTER] (on same line) selects another style.
  • On the next screen you have all the styles available on the calculator.
  • Do not select the bubble on line 6: It is for animations. It will not leave a trace at the end of the plot.

Drawing the Graphs
  • Press [GRAPH] to see the graphs.
  • If one of them is missing, verify that its = is still highlighted, then use the [WINDOW] to set the Window dimensions,
  • Here are the dimensions of the standard window

You can also press [ZOOM] to adjust.


The selection 6:ZStandard sets the dimensions as on the screen Titled Window (above).

In the window screen you can set Xmin=-180, Xmax=180, Xscl=10, Ymin= -0.6, Ymax= 1.5, Yscl=1. The minus here is the change sign (-) to the right of the [.] dot.

When I was trying to get residuals more apperaed

To turn on the residuals, you must turn diagnostics on.

Press 2nd then zero. You are now in an alphabetical catalog list. Go to the d's in the list highlight "diagnostic on" and press enter. This will take you back to the home screen. You must press enter and get the word "done" on the home screen.

If you are trying to get the residuals in a list, you must calculate a regression first. Then when you press 2nd stat, resid should be in that menu.
