IArithmetic 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 + 2i) + (2 + 3i)

*(CPLX)*

@A(i)

AB(i)U

* fx-7400GII: (CPLX)

IAbsolute 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 + 4i, with the angle unit set for degrees
	Imaginary axis

Real axis

2-31
