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, –1 :

•(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
