Common operations in Numeric view
This section applies to the Advanced Graphing, Function, Parametric, and Polar apps.
Numeric view functions that are common to many apps are described in detail in this section. Functions that
are available only in a particular app are described in the chapter dedicated to that app.
Numeric view provides a table of evaluations. Each denition in Symbolic view is evaluated for a range of
values for the independent variable. You can set the range and neness of the independent variable, or leave
it to the default settings.

Zoom
Unlike in Plot view, zooming in Numeric view does not aect the size of what is displayed. Instead, it changes
the increment between consecutive values of the independent variable (that is, the numstep setting in the
Numeric Setup view: see Common operations in Numeric Setup view on page 103). Zooming in decreases the
increment; zooming out increases the increment. The row that was highlighted before the zoom remains
unchanged.
For the ordinary zoom in and zoom out options, the degree of zooming is determined by the zoom factor. In
Numeric view this is the numzoom eld in the Numeric Setup view. The default value is 4. Thus if the current
increment (that is, the numstep value) is 0.4, zooming in will further divide that interval by four smaller
intervals. So instead of x-values of 10, 10.4, 10.8, 11.2, and so on, the x-values will be 10, 10.1, 10.2, 10.3,
10.4, and so on. (Zooming out does the opposite: 10, 10.4, 10.8, 11.2, and so on becomes 10, 11.6, 13.2,
14.8, 16.4, and so on).
