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∠Ƨ) 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

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
Ƨ value of the calculation result is displayed in the range
of –180° Ͻ
Ƨ Ϲ 180°. • Display of the calculation result while Linear Display
is selected will show
a and bi (or r and Ƨ) on separate lines.
