System-wide settings
System-wide settings are values that determine the
appearance of windows, the format of numbers, the scale
of plots, the units used by default in calculations, and
much more.
There are two system-wide settings: Home settings and
CAS settings. Home settings control Home view and the
apps. CAS settings control how calculations are done in
the computer algebra system. CAS settings are discussed
in chapter 3.
Although Home settings control the apps, you can
override certain Home settings once inside an app. For
example, you can set the angle measure to radians in the
Home settings but choose degrees as the angle measure
once inside the Polar app. Degrees then remains the angle
measure until you open another app that has a different
angle measure.
Home settings
You use the Home
Settings input form to
specify the settings for
Home view (and the
default settings for the
apps). Press
SH
(Settings) to open the
Home Settings input
form. There are four pages of settings.
