Caution: When using this TI-82 program, the function you
are graphing must be entered in the Y1 location of the Y=
graphing list. If other functions are entered in the graph-
ing list, this program will not find an appropriate view
for all the functions.
Press followed by the number corresponding to the
PRGM
location of program AUTOSCL. Press
Note: Your program list may or may not look exactly like
the one that is shown to the right.
You are asked to enter Xmin, the value at which the left
side of the view is set. Type 0 and press
Next, you are asked to enter Xmax, the value at which the
right side of the view is set. Type 10 and press
Program AUTOSCL now draws the graph.
Note: In some cases, the graph drawn by the program will
not be the best view. If this happens, follow the instructions
in part 8 to manually set Ymin and Ymax (and/or the scale
values) to obtain a better view.
1.1.4 TI-83: AUTOMATICALLY CHANGING THE VIEW OF THE GRAPH
If your view of the graph is not good or if you do not see the graph, change the view using t h e
built-in autoscaling feature of the TI-83. This option will automatically find a view to see
all the functions that you have turned on in the graphing list.
Be sure the function you are graphing, y = 1000(1 + 0.05)
is entered in the Y1 location of the Y= list. (Delete all
other functions that may be entered in other locations.)
Press
WINDOW
not matter what values are set in the Ymin and Ymax
positions.)
Press
ZOOM
The TI-83 automatically sets the vertical view and
(based on the Xmin and Xmax you set) draws a graph
of the function.
1.1.5 TRACING
You can display the coordinates of certain points on the graph by tracing.
The x-values shown when you trace depend on the horizontal view that you choose, and t h e
y-values are calculated by substituting the x-values into the equation that is being graphed.
