Functions and commands
Many mathematical functions are available from the
calculator’s keyboard. These are described in “Keyboard
functions” on page 307. Other functions and commands are
collected together in the Toolbox menus (
D). There are five
Toolbox menus:
•
Math
A collection of non-symbolic mathematical functions (see
“Keyboard functions” on page 307
)
• CAS
A collection of symbolic mathematical functions (see
“CAS menu” on page 322)
• App
A collection of app functions that can be called from
elsewhere in the calculator, such as Home view, CAS
view, the Spreadsheet app, and in a program (see “App
menu” on page 343)
Note that the Geometry app functions can be called
from elsewhere in the calculator, but they are not
available from the App menu. For that reason, the
Geometry functions are not described in this chapter.
They are described in the Geometry chapter.
