HP Prime Graphing NW280AAABA manual 3seASsE, Plot Function

Preparation

Open the app and plot the graph

Add a constrained point

1.Press SH.

2.On the Home Setting screen set the number format to Fixed and the number of decimal places to 3.

3.Press Iand select Geometry.

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

SJand 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):

3seASsE

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 X 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.

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 E and then press J.

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.)
