Complex Number Calculations
# You can also use ! a ( i ) in place of
K 3 (CPLX)1 (
i ).
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 (1 + 2 i ) + (2 + 3 i )
A K 3 (CPLX)
(b+c 1 (
i ))
+(c+d 1 (
i )) w
Example 2 (2 +
i ) × (2 – i )
A K 3 (CPLX)
(c+ 1 (
i ))
*(c- 1 (
i )) w
k Reciprocals, Square Roots, and Squares
Example (3 +
i )
A K 3 (CPLX)
!x (' )(d+ 1 (
i )) w
k Complex Number Format Using Polar Form
Example 2 ∠ 30 × 3 ∠ 45 = 6 ∠ 75
!m (SET UP)cccccc
1 (Deg)c 3 (
r ∠ θ )J
A c !v ( ∠ )da*d
!v ( ∠ )ef w
