to enter the CALC menu.
When
Ï
˘
are pressed, the screen shown to the
right will appear.
• The CALC function has seven options, 1 to 7, which
are described below.
• However, when Polar, Param, or Seq is selected, only
Value appears as shown on the right.
[1 Value] ....... Calculates the Y-axis value corresponding
to the X-axis value and moves the cursor
pointer to that point on the graph.
[2 Intsct] ........ Calculates the intersection of two graphs
and moves the cursor pointer to that point.
[3 Minimum] .. Calculates the minimum of the given
function graph and moves the cursor
pointer to that position.
[4 Maximum] . Calculates the maximum of the given
function graph and moves the cursor pointer to that position.
[5 X_Incpt] .... Calculates the position where the function graph intersects the X-axis
and moves the cursor pointer to that point.
[6 Y_Incpt] .... Calculates the position where the function graph intersects the Y-axis
and moves the cursor pointer to that point.
[7 Inflec] ........ Calculates the inflection point of the function graph and moves the cursor
pointer to that point.

to scroll the screen.
<Example>
To select any of the above menu items, 1 to 7, press
