Graphing Calculator EL-9450/9400 OPERATION GUIDE
Introduction The EL-9450/9400 was developed to meet the needs of an expanding education market and is based on three concepts: easy to teach, easy to learn and easy to use. The EL-9450/9400 has been designed with simplified operations and time-saving features, allowing teachers to concentrate on actual teaching. This manual was designed to introduce teachers to the unique features of the EL-9450/9400 using detailed operation examples.

Basic operation Guide to key use Press Press to use secondary functions (in yellow). to use the alphabet keys (in blue). SET UP menu Press SET UP . • Contents displayed on the right side of the screen are the current settings. Example: To select “sin”: To select A: ] To select “sin-1”: There may be differences in the results of calculations and graph plotting depending on the SET UP settings.
E quation editor The equation editor allows equations to be viewed just as they are written in textbooks. This aids student comprehension and allows mistakes to be found quickly. Example Input the equation and see how it can be easily viewed with the equation editor. Display Key Operation 1 Clear the display. CL 2 3 4 Notes (or 6 0 a/b 2 X/T a/b X/T Select CALC and (Integral function) ) Enter the range of the integral. 1 1 Enter x 2 Complete equation input.
Shift (Change the location of graphs) Graph shift function helps students grasp the relationship between an equation and its graph. Shift the graph’s location without changing its shape, and the change is immediately reflected in the equation on the right side of the display. Example When the graph of y = x2 is shifted downward, how does this affect the equation? 1 SHIFT/CHANGE Display Notes Enter SHIFT/CHANGE mode. ] Key Operation If SHIFT is not already . highlighted press ] 2 Select shift.
Features Change (Change the shape of the graphs) Graph change function helps students grasp the relationship between an equation and its graph. Change the shape of the graph, and the change is immediately reflected in the equation on the right side of the display. Example When the graph of y = x2 is changed, how does it affect the equation? Key Operation 1 SHIFT/CHANGE Display Notes Enter SHIFT/CHANGE mode and specified ( CHANGE ). 2 Select change. Cursor will move to the equation menu.
Features S lide show Slide show assists with teacher preparation. By selecting from the built-in options or creating your own series of slides, you can demonstrate lessons with minimum preparation time. Example Use the built-in slide show of y = x2 to show how the coordinates change as you move along the graph. Key Operation 1 2 Display Notes Specified SLIDE SHOW mode. Select the built-in menu. 3 Select y = x2 and the first slide appears. 4 Begin the slide show by pressing the cursor key.
Features Built-in slide show selections 1) Y=X2 2) Y=AX+B 3) Y= X 4) Y=1/X 8
Features Built-in slide show selections 5) Y=sinX 6) Y=tanX 7) Y=cos-1X 8) Y=lnX 9
Features Graphing Procedures The EL-9450/9400 has three unique functions that simplify graphing procedures: Rapid Graph, Rapid Window and Rapid Zoom. Of course, the EL-9450/9400 supports conventional graphing procedures as well. Graphing Procedure Following outlines graphing procedures and indicates the steps where Sharp's unique functions can be used to simplify operations. These functions are introduced on the following pages.
Features R apid 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. Example Draw the graph for y = 2sin (-2x+ ) + 2 using the rapid graph function. Key Operation 1 Y= 2 EZ Display Notes Enter the equation entry mode. Enter Rapid Graph mode and view the equation-type menu. 3 Select the type of equation: Trigonometric, and view the equation format menu.
Features R apid window Rapid window simplifies setting window size with a range of preset values. Use in conjunction with the rapid graph function or with any graph created. Example 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. Key Operation Enter Rapid Window mode. EZ Select the No. 3 style and view the X-range menu. 3 4 (Five times) (or 5 5 Notes Enter viewing window setup mode.
Features R apid 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. Example Adjust the viewing window for y = x3 + x2 - 2x to show the entire graph. Key Operation 1 Y= X/T X/T x ab 2 2 (–) Display 3 X/T 3 3 5 1 1 (–) 1 5 Notes 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.
