EL-9400 Graphing Calculator 10 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. Step 1 Input equation Step 2 Set X, Y range Xmin = Xmax = Xscl = Ymin = Ymax = Yscl = Step 3 Draw graph Step 4 Adjust viewing window Manual Input Graphing Procedure Y = EZ EZ EZ Rapid Graph Manual Input Rapid Window Manual Input Rapid Zoom Press Graph button to draw graph.Simply select from built-in menu to modify desired type of equation . Simply select from built-in menu to set window size. Use arrows to adjust window size while viewing graph. Go back to Step 2 to readjust window size.

EL-9400 Graphing Calculator NotesKey OperationDisplay Example 11 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 of equation: Trigo- nometric, and view the equation format menu. Draw the graph. (Note: Previous range values may affect the viewing window. To reset range values, use Rapid Window.) 1 2 3 4 5 6 Select the second equation style and input. If necessary, make changes to the coefficients. Y = EZ Features
EL-9400 Graphing Calculator NotesKey OperationDisplay Example 12 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. 1 2 3 4 5 7 Select the No. 3 style and view the X-range menu. Enter Rapid Window mode. Select the Y-range and draw the graph. Move the cursor to No. 5: (-0.5 < Y < 5 scl=0.5)Enter viewing window setup mode. EZ (Five times) Select X-range No. 4: (-1 < X < 10 scl=1), and view the Y-range menu. Features (or 5 ) (or 5 ) (Six times)
EL-9400 Graphing Calculator NotesKey OperationDisplay Example 13 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. 1 2 3 4 Create the graph y = x3 + x2 - 2x using the following conditions: X-range: xmin = -3 xmax = 3 xscl = 1 Y-range: ymin = -1.5 ymax = 1.5 yscl = 0.5 View display (adjusted). Enter Rapid Zoom mode. 5 Change X-range from Ymax = 1.5 to Ymax=2. Draw the graph. EZ Features Y = 1 5 (–)33 1(–)51 5 Repeat: Change Y-range from Ymax = 2 to Ymax=2.5.
