CHAPTER 4
<Example>
Input "Y1 = 2sin(-2X + π) + 2" using the rapid graph function.
1. Press to open the equation input screen and
place the cursor at [Y1].
2. Press to display the large classification screen for
the equation.
3. Since the sine function is included in [TRIG], select
[TRIG]. There are three methods shown below to
select [TRIG].
• Touch [4 TRIG] with the pen.
• Press 4 ®.
• Press ≥ ®. (Assuming the cursor pointer is
initially located at X
• The screen enters the medium classification screen
on which actual equations are displayed.
4. To select the sine graph, move the cursor to A (current
position) and press ®.
• The small classification screen shown to the right
will appear.
5. Press 2 ® to input a desired equation to Y1.
* At this time, pressing
However, the equation selected using the rapid graph
function does not have any graph range. Therefore, the
graph is drawn based on the current window settings.
* To return to the normal function calculation screen from the
rapid graph mode, press Ï œ.
* To return to the initial screen of RAPID GRAPH, press ¬.
* The entire equation cannot be displayed when the number of
digits exceed one line. Use <> to check the equation.
