Preparation 1. P r e s s SH.

2. On the Home Setting screen set the number format to

Fixed and the number of decimal places to 3.

Open the app

and plot the

graph

3. Press I and select Geometry.

If there are objects showing that you don’t need, press

SJ and confirm your intention by tapping .

4. Select the type of graph you want to plot. In this example

we are plotting a simple sinusoidal function, so choose:

> Plot > Function

5. With plotfunc( on the entry line, enter 3*sin(x):

seASsE

Note that x must be entered in lowercase in the

Geometry app.

If your graph doesn’t

resemble the illustration

at the right, adjust the

Rng

and Y Rng values

in Plot Setup view

(

SP).

We’ll now add a point

to the curve, a point that

will be constrained always to follow the contour of the

curve.

Add a

constrained

point

6. Tap and select Point On.

Choosing Point On rather than Point means that the

point will be constrained to whatever it is placed on.

7. Tap anywhere on the

graph, press

and then press

Notice that a point is

added to the graph and

given a name (B in this

example). Tap a blank

area of the screen to

deselect everything. (Objects colored cyan are selected.)
