Complex-

Number

Functions

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 (x,y), where x

is the real part and y is the imaginary part.

ARC

Argument. Finds the angle defined by a complex number.

Inputs and outputs use the current angle format in Modes.

ARG{ ir,0) )

CONJ

Complex conjugate. Conjugation is the negation (sign reversal)

of the imaginary part of a complex number.

CONJ( lx,y) }

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

IM ((x,y))

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

RE ((X,y))
