Complex number functions

ARC

CONJ

These functions are for complex numbers only. You can also

use complex numbers with all trigonometric and hyperbolic

functions, and with some real-number and keyboard
functions. Enter complex numbers in the form (.v.y), where a:

is the real part and y is the imaginary part.

Argument. Finds the angle defined by a complex number.

Inputs and outputs use the current angle format set in Modes.

ARGCCr.y))

Example

ARG ( ( 3 , 3 ) ) returns 4 5 (Degrees mode)

Complex conjugate. Conjugation is the negation (sign
reversal) of the imaginary part of a complex number.

CONJ((x,y))

Example

CONJ ( ( 3 , 4 ) ) returns ( 3 , - 4 )

Imaginary part, y, of a complex number, (x,y).

IM ((x,y))

Example

IM ( ( 3 , 4 ) ) returns 4

Real part x, of a complex number, (x,y).

RE((x,y))

Example

RE ( ( 3 , 4 ) ) returns 3
