I 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+3i)
*(CPLX)*
@A(
i)
AB(
i)U
* fx-7400G
II: (CPLX)
I Reciprocals, Square Roots, and Squares
Example (3 + i)
*(CPLX)*
V()B(
i)U
* fx-7400G
II: (CPLX)
I Complex Number Format Using Polar Form
Example 230 s 345=675
K(SET UP)AAAAAA*
(Deg)A(
rƧ))
AT()B?B
T()CDU
* fx-7400G
II, fx-9750GII: AAAAA
I 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 value²Z²and 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
