2. Display the coefficient menu.

4(VAR) or w

Coefficient whose value will change

• {SEL} ... {selects dynamic coefficient}

• {RANG} ... {dynamic coefficient range settings}

• {SPEED} ... {dynamic Graph drawing speed}

• {AUTO} ... {automatic setting of end and pitch values to match coefficient

values}

• {DYNA} ... {dynamic Graph draw operation}

• The calculator automatically makes the first variable it finds the dynamic

coefficient. To select a different coefficient, use c and f to move the

highlighting to the coefficient you want to use, and the press 1 (SEL).

• The letters representing each coefficient are variables, and so the values that

appears on the screen are those currently assigned to each variable. If a

complex number is assigned to a variable, only the integer part appears.

• All variables contained in the currently selected function appear on the display

in alphabetical order.

• If there is more than one function that can be drawn using Dynamic Graph, the

message "Too Many Functions" appears on the display.

• If the value of the dynamic variable is zero and you press 5 (AUTO), the

dynamic variable automatically changes to 1 and Dynamic Graphing is

performed.

3. Specify the value of each coefficient.

cw-bw-bw

• If there is more than one coefficient, use f and c to move the highlighting

to each coefficient and input its value.

• Values you input for coefficients are also assigned to the corresponding

variable.

4. Recall the coefficient range menu.

2(RANG)

• The range you set remains in effect until you change it.
