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 + 2i) + (2 + 3i) *(CPLX)* @ A(i) A B(i)U * fx-7400GII: (CPLX) I Reciprocals, Square Roots, and Squares Example (3 + i) *(CPLX)* V()B (i)U * fx-7400GII: (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-7400GII, 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 value²Z ²and 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 2-31 Real axis
