k Arithmetic Operations [OPTN]-[CPLX]-[i]
Arithmetic operations are the same as those you use for manual calculations. You can even
use parentheses and memory.
Example (1 + 2
i) + (2 + 3 i)
AK3(CPLX)
!*( ( )b+c1(
i)!/( ) )
+!*( ( )c+d1(
i)
!/( ) )w
k Reciprocals, Square Roots, and Squares
Example (3 + i)
AK3(CPLX)
!x(')!*( ( )d+
1(
i)!/( ) )w
k Complex Number Format Using Polar Form
Example 2 ∠ 30 × 3 ∠ 45 = 6 ∠ 75
!m(SET UP) cc1(Deg)c
3(

k Absolute Value and Argument [OPTN]-[CPLX]-[Abs]/[Arg]
The unit regards a complex number in the form
a + bi as a coordinate on a Gaussian plane,
and calculates absolute value ⎮ Z⎮ and argument (arg).
Example To calculate absolute value (
r) and argument ( Ƨ) for the complex number
3 + 4 i, with the angle unit set for degrees
Imaginary axis
Real axis
