: applies common simplification rules to reduce an

expression to its simplest form. For example,
a + LN(b*e c )
simplify(e
: copies a selected entry ion history to the entry

line
: displays the selected entry in full-screen mode,
•
with horizontal land vertical scrolling enabled. The entry
is also presented in textbook format.
With one exception, you perform calculations in CAS view
just as you do in Home view. (The exception is that there is no
RPN entry mode in CAS view, just algebraic and textbook
modes). All the keys work in the same way in CAS view as
Home view. The primary difference is that the default display
of answers is symbolic rather than numeric.
You can also use the template key (
framework for common calculations (and for vectors and
matrices). This is explained in detail in "Math template" on
page 21.
The most commonly used
CAS functions are available
from the CAS menu, one of
the Toolbox menus. To
display the menu, press
D
. (If the CAS menu is not
open by default, tap
.) Other CAS
commands are available from the CATLG menu (another of
the Toolbox menus).
To choose a function, select a category and then a command.
To find the roots of 2x
