You can enter a complex list, vector, or matrix directly. The syntax below is for lists. To
enter a complex vector or matrix, substitute brackets for braces below and use the correct
form for either data type (Chapters 12 and 13).
In rectangular form, to use lists of complex numbers with
syntax is:
realA imaginaryA
conj{( ,
In polar form, to use lists of complex numbers with
syntax is:
magnitudeA angleA
real{( ±
When you use a list the TI-86 calculates the result element by element and returns a list, in
which each element is expressed according to the complex mode setting.
Returns the polar angle of a complex number, list, vector, or matrix
