7The Toolbox Menus
Comprehensive menus of functions, commands, and variables are grouped together in a set of five menus known as the Toolbox
menus. You press the Toolbox key (
D) to display these menus, labeled Math, CAS, App, User, and Catlg.
As well as the two usual techniques for selecting a menu item—tapping on it, or using the cursor keys to highlight it and then
pressing
E—you can also type part of the name of the item and the cursor will jump to it. You can also enter the number of
the item as it appears on the menu. (The latter technique is illustrated on
page 11 .)
Math Menu
This menu contains all the math functions available to you in Home view, arranged by category. Press D and, if necessary, tap
. Select the appropriate category and then choose the function you want. For example, suppose you want to determine the
complex conjugate of the complex number 6+4*i:
1. Press D (and tap if necessary).
2. Select Arithmetic from the main menu, Complex from the sub-menu, and Conjugate from the
sub-sub-menu.
The appropriate syntax—CONJ()—appears on the entry line ready for you to specify the
complex number.
3. Enter 6+4*i between the parentheses and press E. The result is 6–4*i.
Menu format
By default, a function is presented on a math menu using its descriptive name, not its command name. Thus the command name
CONCAT is presented as Concatenate and MOD is presented as Modulus. If you prefer the math menus to show the command
names instead, deselect the
Menu Display option on page 2 of the Home Settings screen (see page 4 above). Note that this
also affects the format of the CAS menus.
