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
