5-8-1 Dynamic Graphing 5-8 Dynamic Graphing k Using Dynamic Graph Description 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. Set Up 1. From the Main Menu, enter the DYNA mode. 2. Make V-Window settings. Execution 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.*1 5. Input values for coefficients, and specify which coefficient 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. *1The following are the seven built-in function types. •Y=AX+B •Y=A(X-B)2+C •Y=AX2+BX+C •Y=AX^3+BX2+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=)". *2You 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. 20050401
