Complex NumberCalculations (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 + 6i) ÷ (2i) = 3 – i (Complex number format: a + bi)

(2 +6 W(i))/(2 W(i))= 3–i

2 ∠ 45 = '2 + '2 i Bv (Complex number format: a + bi)

2 1-(∠) 45 = '2 +'2 i

'2 + '2 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.
