The User menu lists user-defined functions and programs. For example, using the
Define feature (Sc) you can define your own functions. The name you give to a
function will appear on the User menu. You could, for instance, create the function
SIN(X)+COS(Y) and name it SINCOS. SINCOS will then appear on the User menu. If
you choose it, SINCOS() will appear at the position of the cursor. You then enter the
arguments you specified when creating the function. Thus SINCOS(0.5,0.75) will
yield 1.2111... (if your angle measure setting is radians).
Programs you create using the calculator's programming language are also listed on
the User menu if you have made them global (by using the
command). Just as
you can evaluate a user-defined function by first selecting it from the User menu, you can also run a program by selecting it
from the User menu.
Catalog Menu (Catlg)
The Toolbox key also gives you access to a menu of every command and function
available on the HP Prime calculator. Tap
and tap the command or function
you want. It is copied to the location of the cursor.
There are over 400 commands and functions on this menu. You may find it easier to
select an item by entering the first few letters of its name. The menu automatically
scrolls to the first command whose name matches the letters you entered. For
example, suppose you want to find the number of positive integers not greater than
and coprime to 200. Euler's totient function is a quick way of finding that number, and
the function is available on the Catlg menu.
1. Press b (and tap
2. Enter eu. Notice that the menu immediately scrolls to euler.
3. Select euler, enter 200 between the parentheses, and press E. The result is 80.
Catalogs and Editors
The HP Prime calculator provides a number of handy catalogs where you can store the lists, matrices, programs, and notes
you create. Each of these catalogs has an editor to help you quickly create and modify a list, matrix, program, or note. Like
apps, the items you add to a catalog can be sent to another HP Prime calculator using the supplied USB cable (see "Data
sharing" on page 20).
