Complex Number Calculations

kAbsolute 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 (θ) for the complex

number 3 + 4i, with the angle unit set for degrees

Imaginary axis

Real axisAK3(CPLX)2(Abs)(d+e1(i))w(Calculation of absolute value)AK3(CPLX)3(Arg)

(d+e1(i))w

(Calculation of argument)kConjugate 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 + 4iAK3(CPLX)4(Conj) (c+e1(i))w

#The result of the argument calculation differs in accordance with the current angle unit setting (degrees, radians, grads).
