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
2
.)
• 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
immediately draws the graph.
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.
