Complex numbers
You can perform arithmetic operations using complex
numbers. Complex numbers can be entered in the
following forms, where x is the real part, y is the
imaginary part, and i is the imaginary constant, :
• (x, y)
• x + yi (except in RPN mode)
• x – yi (except in RPN mode)
• x + iy (except in RPN mode), or
• x – iy (except in RPN mode)
To enter i:
• press
ASg
or
• press
Sy.
There are 10 built-in variables available for storing
complex numbers. These are labeled Z0 to Z9. You can
also assign a complex number to a variable you create
yourself.
To store a complex
number in a variable,
enter the complex
number, press ,
enter the variable that
you want to assign the complex number to, and then press
E
. For example, to store 2+3i in variable Z6:
R2o3>Ay6E
Sharing data
As well as giving you access to many types of
mathematical calculations, the HP Prime enables you to
create various objects that can be saved and used over
and over again. For example, you can create apps, lists,
matrices, programs, and notes. You can also send these
objects to other HP Primes. Whenever you encounter a
