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 dierent angle measure.
