9. Dynamic Graphing

Using Dynamic Graph
Dynamic Graph lets you define a range of values for the coefficients in a function, and then
observe how a graph is affected by changes in the value of a coefficient. It helps to see how
the coefficients and terms that make up a function influence the shape and position of a graph.
1. From the Main Menu, enter the Dyna Graph mode.
2. Configure V-Window settings.
3. On the Setup screen, specify the Dynamic Type.
1
(Cont) ... Continuous
2
(Stop) ... Automatic stop after 10 draws
4. Use the cursor keys to select the function type on the built-in function type list.*
1
5. If required, press
!
f
(FORMAT) and use the dialog box that appears to specify the
graph color.
6. Input values for coefficients, and specify which coefficient will be the dynamic variable.*
2
7. Specify the start value, end value, and increment.
8. Specify the drawing speed.
3
(SPEED)
1
( ) .... Pause after each draw (Stop&Go)*
3
2
( ) ...... Half normal speed (Slow)
3
( ) ...... Normal speed (Normal)
4
( ) ..... Twice normal speed (Fast)
9. Draw the Dynamic Graph.

The following are the seven built-in function types.
• Y=A
x
+B • Y=A(
x
−B) 2 +C • Y=A
x
2 +B
x
+C • Y=A
x
^3+B
x
2 +C
x
+D
• Y=Asin(B
x
+C) • Y=Acos(B
x
+C) • Y=Atan(B
x
+C)
After you press
3
(TYPE) and select the function type you want, you can then input the
actual function.

You could also press
w
here and display the parameter setting menu.

When “Stop&Go” is selected as the drawing speed, starting a Dynamic Graph draw operation
will cause drawing of the graph with the initial variable values to stop. Each press of
w
sequentially displays the graph of the next variable value. Also, you can scroll to the graph of
the next variable value by pressing
e
(or
+
) or to the graph of the previous variable value
by pressing d (or
-
). To exit the Dynamic Graph draw operation, press
J
.
• The message “Too Many Functions” appears when more than one function is selected for
Dynamic Graphing.
