GRAPHING FUNCTIONS
Sequential
Memory capacity: 3 equations
(u(
n
), v(
n
), w(
n
)) and 3 lists
(u(
n
Min), v(
n
Min), w(
n
Min))
• In each function input screen, the cursor pointer indicates the equation number
where an input can be made.
• When a function input screen is opened, the cursor appear on the right of the “=”
sign of the top equation number.
• When a function is entered, the cursor pointer moves to the next character.
• Pressing ® completes the entry of the function to the equation number. At the
same time, the cursor pointer moves to the equation number immediately below.
• The “=” sign of the equation for which an input is made becomes “
=
” (highlighted).
This indicates that the graphing function is valid. (When
is pressed, the graph of
the highlighted equation is drawn.)
When the graph display is not necessary, use <, >, ≤, and ≥ to
move the cursor to the “=” sign of the selected equation number, and press ®.
This changes the sign to “=” to indicate that the graphing function is inactive.
• If an equation does not fit in a single line, it automatically wraps to the beginning of
the next line. (When the one line edit mode is selected.)
•
is used to enter a variable in each of the above modes.
• Pressing
allows the input of X in the X-Y coordinate system, θ in the polar
coordinate system, T in the parametric coordinate system, and
n
in the sequence
coordinate system.
• To delete or change an entered expression, move the cursor to the correction
position using <, >, ≤, and ≥, and make necessary changes.
