angle (

real

,

)

Returns the polar angle of a complex number, list, vector, or matrix
calculated as

tan

L

(adjusted by

p in the second

quadrant or

L

p in the third quadrant); the result is tan

±angle

)

Returns angle (where

L

p<anglep)

Rec

Displays complexValue in rectangular format

(

)

,

regardless of complex mode setting; valid only at the end of a command
and only when complexValue is indeed complex

Pol

Displays complexValue in polar format (magnitude

of complex mode setting; valid only at the end of a command and only
when complexValue is indeed complex

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

conj

,

real

,

imag

,

abs

, and

angle

, the

syntax is:

conj{(

realA

,

imaginaryA

),(

realB

,

imaginaryB

),(

realC

,

imaginaryC

),

...

}

In polar form, to use lists of complex numbers with

conj

,

real

,

imag

,

abs

, and

angle

, the

syntax is:

real{(

magnitudeA

±

angleA

),(

magnitudeB

±

angleB

),(

magnitudeC

±

angleC

),

...

}

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.

Select { and } from the LIST
menu.

You must enter commas to
separate list elements.
