HELP and press . The menu of help topics
appears.
Each help topic includes the required syntax, along with
real sample values. You can copy the syntax, with the
sample values, to the HOME screen or to the Equation
Writer, by pressing .

CAS functions in the Equation Writer
You can display a menu of CAS functions in four ways:
• by displaying the MATH menu from HOME and then
pressing , or
• opening the Equation Writer and pressing ,
• opening the Equation Writer and selecting a function
from a soft-key menu, or
• opening the Equation Writer and pressing
.
You can also directly type the name of a CAS function
when you are in ALPHA mode.
Note that in this section, CAS functions available from the
sot-key menus in the Equation Writer are described. CAS
functions available from the MATH menu are described in
“CAS Functions on the MATH menu” on page 14-45.
NOTE
When using CAS, you should be aware that the required
syntax will vary depending on whether you are applying
the command to an expression or a function. All CAS
commands are designed to work with expressions; that is,
they take expressions as arguments. If you are going to
use a function—for example, F—you need to specify an
expression made from this function, such as F(x), where x
is the independent variable.
