Complex Number Calculations (CMPLX)

To perform complex number calculations, first press N2(CMPLX) to

enter the CMPLX Mode. You can use either rectangular coordinates (

a+bi)

or polar coordinates (

r∠) to input complex numbers. Complex number

calculation results are displayed in accordance with the complex number

format setting on the setup menu.

(2 + 6

i) ÷ (2i) = 3 – i (Complex number format: a + bi)

( 2 + 6 W(

i))/( 2 W(i))= 3–i

∠ 45 = 1 + i Bv (Complex number format: a + bi)

! 2 e1-(∠) 45 =

1+i

i = 2 ∠ 45 Bv (Complex number format: r∠)

! 2 e+! 2 eW(

i)= 2∠45

Note: • If you are planning to perform input and display of the calculation

result in polar coordinate format, specify the angle unit before starting the

calculation. • The

 value of the calculation result is displayed in the range

of –180° 

  180°. • Display of the calculation result while Linear Display

is selected will show

a and bi (or r and ) on separate lines.

CMPLX Mode Calculation Examples

(1 – i)

–1

B (Complex number format: a + bi)

( 1 -W(

i))E=

(1 + i)

+ (1 – i)

= – 4 – 2i B

( 1 +W(

i))6 4 e+( 1 -W(i))w= –4–2i

To obtain the conjugate complex number of 2 + 3i (Complex number

format: a + bi)

12(CMPLX)2(Conjg) 2 + 3 W(

i))= 2–3i

To obtain the absolute value and argument of 1 + i Bv

Absolute Value: D 1 +W(

i)= 1.414213562

Argument: 12(CMPLX)1(arg)1+W(i))= 45

Using a Command to Specify the Calculation Result

Format

Either of two special commands ('r∠ or 'a+bi) can be input at the end

of a calculation to specify the display format of the calculation results. The

command overrides the calculator’s complex number format setting.
