(d+e1 ( i ))w
(Calculation of absolute value)
A K3 (CPLX)3(Arg)
(d+e1 ( i ))w
(Calculation of argument)
• The result of the argument calculation differs in accordance with the current
angle unit setting (degrees, radians, grads).
k k k k k Conjugate Complex Numbers
[OPTN]-[CPLX]-[Conj]
A complex number of the form a + bi becomes a conjugate complex number of the
form a – bi .
