Complex Number Calculations
(CMPLX)
To perform complex number calculations, first press (CMPLX) to enter the CMPLX Mode. You can use either rectangular coordinates (a+bi) or polar coordinates (rθ) 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 $(i)2 $(i)
2 45 = '2 + '2 i B(Complex number format: a + bi)
2 () 45 '2 +'2 i
'2 + '2 i = 2 45 B(Complex number format: rθ)

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 θ value of the calculation result is displayed in the range of
