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 (rθ) 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) 3–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: rθ)

2 C2 C$(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 θ value of the calculation result is displayed in the range of –180° θ 180°. • Display of the calculation result while Linear Display is selected will show a and bi (or r and θ) on separate lines.
