*(CPLX)*(Abs) B C(i)U (Calculation of absolute value) * fx-7400GII: (CPLX) *(CPLX)*(Arg) B C(i)U (Calculation of argument) * fx-7400GII: (CPLX) • The result of the argument calculation differs in accordance with the current angle unit setting (degrees, radians, grads). I Conjugate Complex Numbers [OPTN]-[CPLX]-[Conj] A complex number of the form a + bi becomes a conjugate complex number of the form a - bi. Example To calculate the conjugate complex number for the complex number 2 + 4i *(CPLX)*(Conj) A C(i)U * fx-7400GII: (CPLX) I Extraction of Real and Imaginary Parts [OPTN]-[CPLX]-[ReP]/[lmP] Use the following procedure to extract the real part a and the imaginary part b from a complex number of the form a + bi. Example To extract the real and imaginary parts of the complex number 2 + 5i *(CPLX)*(E)(ReP) A D(E)(i)U (Real part extraction) * fx-7400GII: (CPLX) *(CPLX)*(E)(ImP) A D(E)(i)U (Imaginary part extraction) * fx-7400GII: (CPLX) I Polar and Rectangular Form Transformation [OPTN]-[CPLX]-[rƧ]/[a+bi] Use the following procedure to transform a complex number displayed in rectangular form to polar form, and vice versa. 2-32
