Using Calculation Modes
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.
Example 1: (2 + 6i) ÷ (2i) = 3 - i (Complex number format: a+bi)
2 6 (i) 2 (i) 3-i
Example 2: 2∠45 = √2 + √2i (MthIO-MathO) (Angle unit: Deg)
(Complex number format: a+bi)
2 (∠) 45
√2+√2i
Example 3: √2 + √2i = 2∠45 (MthIO-MathO) (Angle unit: Deg)
(Complex number format: r∠θ)
2 2 (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.
