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.

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.

When the graph of y = x2 is shifted downward,

how does this affect the equation?

View the result of the shift.

Select the location of the shift:
move cursor down twice.

Slide sho w

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.

Use the built-in slide show of y = x2 to show how the

coordinates change as you move along the graph.

Select y = x2 and the first slide
appears.

Moving between the values you
can follow the changes in the
graph’s coordinates, making the
nature of the graph easier to
understand.

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.

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: Trigo­nometric, 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.)
