k Using Dynamic Graph

Dynamic Graph lets you defi ne a range of values for the coeffi cients in a function, and then 
observe how a graph is affected by changes in the value of a coeffi cient. It helps to see how 
the coeffi cients and terms that make up a function infl uence the shape and position of a 
graph.

1. From the Main Menu, enter the DYNA mode.

2. Make V-Window settings.

3. On the Setup screen, specify the Dynamic Type.

1(Cnt) ... 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. Input values for coeffi cients, and specify which coeffi cient will be the dynamic 

variable.*

2

6. Specify the start value, end value, and increment.

7. Specify the drawing speed.

3(SPEED)1(

) ..... Pause after each draw (Stop&Go)

   

 

2( ) ....... Half normal speed (Slow)

   

 

3( ) ....... Normal speed (Normal)

   

 

4( ) ...... Twice normal speed (Fast)

8. Draw the Dynamic Graph.

 The following are the seven built-in function 

types. 
  •Y=AX+B
  •Y=A(X–B)

2

+C

  •Y=AX

2

+BX+C

  •Y=AX^3+BX

2

+CX+D

  •Y=Asin(BX+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. 

1(Y=) ... rectangular coordinate expression
2(r=) ... polar coordinate expression
3(Parm) ... parametric function

Entering the DYNA mode when a Function 
Type that is not one of the three types listed 
above is selected in the GRAPH mode causes 
the Function Type to change automatically to 
“rectangular coordinate expression (Y=)”.

 You could also press 

w here and display the 

parameter setting menu.

# The message “Too Many Functions” appears 

when more than one function is selected for 
Dynamic Graphing.
