2. Display the coefficient menu.
4 (VAR) or w
Function being graphed
Coefficient whose value will change
Coefficients in function
• { 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.
c w- b w- b w
• 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 dynamic coefficient range setting menu.
2 (RANG)
• The range you set remains in effect until you change it.
