CAS menu
Press
D
to open the
Toolbox menus (one of which
is the CAS menu). The
functions on the CAS menu
are those most commonly
used. Many more functions
are available. See “Ctlg
menu”, beginning on page
338.
Note that the Geometry functions appear on the CAS menu
when the Geometry app is currently active or was the last-
used app. They are described in “Geometry functions and
commands”, beginning on page 151.
