• { 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 coefficient range menu.

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