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 + b i )
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 ) ÷ (2 i ) = 3 – i (Complex number format: a + b i )
( 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
 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 b i (or r and  ) on separate lines.
