Graphing Procedures
The EL-9400 has three unique functions that simplify graphing procedures: Rapid Graph,
Rapid Window and Rapid Zoom. Of course, the EL-9400 supports conventional graphing
procedures as well.
Following outlines graphing procedures and indicates the steps where Sharps unique functions can
be used to simplify operations. These functions are introduced on the following pages.

Rapid graph
Graphing  has never been easier. With its full range of preset equations, rapid graph
simplifies equation input. Use in conjunction with the rapid window function or with any
graph created.
Draw the graph for  y = 2sin (-2x+  ) + 2
using the rapid graph function.
Enter the equation entry mode.
Enter Rapid Graph mode and view
the equation-type menu.
Select the sin equation format and
view the sin equation style. Select the type...

Rapid window
Rapid window simplifies setting window size with a range of preset values. Use in con-
junction with the rapid graph function or with any graph created.
After using Rapid Graph to draw the graph of y = 2sin (-2x+   ) + 2 (refer
p. 11), set the viewing window using the rapid window function.

Rapid zoom
Rapid zoom offers one-touch adjustment of window size while viewing the graph. No more
guessing or wasting class time to find optimal values for window size.
 Adjust the viewing window for y = x3 + x2 - 2x
to show the entire graph.
