CAS menu
By default, a CAS function is presented on a CAS menu using its descriptive name, not its command name. Thus the command
name
gbasis
is presented as
Groebner Basis
and
proot
is presented as
Find Roots
. If you prefer the CAS menus to
show the command names instead, deselect the
Menu Display
option on page 2 of the
Home Settings
screen (see page 4
above).
Using CAS in Home view
You can use a CAS function in Home view. Just select the function from the CAS menu while you are entering your expression. The
CAS.
prefix is added to your CAS function to remind you that this component of your expression will be evaluated by the CAS.
You can also copy an item from CAS history to an expression you are entering in Home view. Press
Z
and select
Get from
CAS
. The CAS view opens. Tap the item you want and it is copied directly to the cursor position in Home view. Likewise you can
insert an item from Home view history into an expression you are entering in CAS view. Just press
Z
and select
Get from
Home
. Home view opens. Tap the item you want and it is copied directly to the cursor position in CAS view.
