9. Dynamic Graphing
k 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.*

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.

1
The following are the seven built-in function types.
• Y=A
x+B • Y=A(x−B)
2
+C • Y=Ax
2
+Bx+C • Y=Ax^3+Bx
2
+Cx+D
• Y=Asin(B
x+C) • Y=Acos(Bx+C) • Y=Atan(Bx+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.
