HP Prime Graphing NW280AAABA manual Szj AaE, Szj AQAcE, Example To assign π2 to to the variable a

Example: To assign π2 to to the variable A:

SzjAaE

Your stored value appears as shown at the

right. If you then wanted to multiply your stored value by 5, you could enter: Aas5E.

You can also create your own variables in Home view. For example, suppose you wanted to create a variable called ME and assign π2 to it. You would enter:

Szj AQAcE

A message appears asking if you want to create a

variable called ME. Tap or press Eto confirm your intention. You can now use that variable in subsequent calculations: ME*3 will yield 29.6088132033, for example.

You can also create variables in CAS view in the same way. However, the built-in CAS variables must be entered in lowercase. However, the variables you create yourself can be uppercase or lowercase.

See chapter 22, “Variables”, starting on page 423 for more information.

As well as built-in Home and CAS variables, and the variables you create yourself, each app has variables that you can access and use in calculations. See “App functions and variables” on page 109 for more information.
