Press K3(COMPLEX) to display the complex calculation number menu, which contains
the following items.
• { i } ... {imaginary unit i input}
• { Abs } / { Arg } ... obtains {absolute value}/{argument}
• { Conjg } ... {obtains conjugate}
• { ReP } / { ImP } ... {real}/{imaginary} part extraction
• { '
r ∠ } / { 'a + bi } ... converts the result to {polar}/{rectangular} form
• You can also use !a( i ) in place of K3(COMPLEX) 1( i ).
• Solutions obtained by the Real,
a + b i and r ∠ modes are different for power root (
x
'
)
calculations when x < 0 and y = m / n when n is an odd number.
Example: 3
x
' (– 8) = – 2 (Real)
= 1 + 1.732050808 i ( a + b i )
= 2 ∠ 60 ( r ∠ , Deg mode)
• To input the “ ∠ ” operator into the polar coordinate expression (
r ∠ ), press !v( ∠ ).
k Arithmetic Operations [OPTN] - [COMPLEX] - [ 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(COMPLEX)
(b+c1(
i ) )
+(c+d1(
i ) )w
k Reciprocals, Square Roots, and Squares
Example (3 + i )
AK3(COMPLEX)
!x( ') (d+1(
i ) )w
