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.
* Option 7 will not appear on the first screen. Press ≥ to scroll the screen.
<Example>
To select any of the above menu items, 1 to 7, press Ï ˘, and a desired
