Chapter 3: Graph & Table Application 104

To do this on the Graph window: Do this:

Automatically configure settings so the Graph screen fills the entire

screen in accordance with the graph being drawn

Tap [Zoom] and then [Auto], or

tap R.

Return a graph to its original View Window settings Tap [Zoom] and then [Original].

Adjust View Window

x-axis values so that they are identical to the y-axis

values

Tap [Zoom] and then [Square].

Round View Window settings (

xmin, xmax, xdot) to an appropriate

number of decimal places and redraw the graph

Tap [Zoom] and then [Round].

Make the value of each dot equal 1, which makes all coordinate values

integers

Tap [Zoom] and then [Integer].

Return View Window parameters to their settings prior to the last zoom

operation

Tap [Zoom] and then [Previous].

Return View Window parameters to their initial default (see “Initial

(Default)” under “View Window Preset Parameters” on page 102)

Tap [Zoom] and then [Initialize].

Redraw graphs using preset View Window parameter values See “Using Quick Zoom” below.

Using Quick Zoom

The quick zoom commands on the [Zoom] menu draw a graph using preset built-in View Window parameter

values.

Note: The values in the explanations below apply during the half-size view of the Graph window (which is the

initial default setting of the Graph & Table application). Tapping r on the icon panel will switch to the

full-screen view and change the View Window settings.

*1 Any View Window parameter that is not shown in the above table is unchanged when you execute a quick

zoom command.

*2 Depending on the Basic Format Angle setting, executing Quick Trig changes the

xscale setting to π/2 (for

Radian), 90 (for Degree), or 100 (for Grad). The following settings are applied based on the xscale value:

xmin = –7.7 × xscale, xmax = 7.7 × xscale.

Using Built-in Functions for Graphing

Your ClassPad is pre-programmed with the commonly used functions listed below. You can recall a built-in

function, assign values to its coefficients, and graph the results.

y = aⴢx + by = aⴢcos (bⴢx + c) + dy = aⴢe^(bⴢx + c) + d

= aⴢx^2 + bⴢx + cy = aⴢtan (bⴢx + c) + dy = a^(bⴢx + c) + d

= aⴢx^3 + bⴢx^2 + cⴢx + dy = aⴢlog (bⴢx + c) + dy = a /(bⴢx + c) + d

= aⴢsin (bⴢx + c) + dy = aⴢln (bⴢx + c) + d

Note: Built-in functions are graphed automatically and cannot be used for input on the Graph Editor window.
