A complex number z = x+iy or (x, y) can be also represented as (r, θ) in polar coordinate, where r = √(x2+ y2) and θ = tan-1(y/x). Here θ is known asArg(z). And the values of θ in

]-π, π] is known as principal value of the argument and is represented as arg(z). It is evident that Arg(z) = arg(z) + 2nπ.

What is the difference between principal argument and argument of a complex number?

PRINCIPAL ARGUMENT = ARGUMENT + 2nPI arg(Z) = Arg (Z) + 2nPI


How do you find the argument of the complex number -2-i?

arg(-2-i) = sqrt[22 + 12] = sqrt(5)


Why and what is principle argument of complex number?

A complex number (z = x + iy) can be plotted the x-y plane if we consider the complex number the point (x,y) (where x is the real part, and y is the imaginary part). So once you plot the complex number on the x-y plane, draw a line from the point to the origin. The Principle Argument of z (denoted by Arg z) is the measure of the angle from the x-axis to the line (made from connecting the point to (0,0)) in the interval (-pi, pi]. The difference between the arg z and Arg z is that arg z is an countably infinite set. And the Arg z is an element of arg z. Why? : The principle argument is needed to change a complex number in to polar representation. Polar representation makes multiplication of complex numbers very easy. z^2 is pretty simple: just multiply out (x+iy)(x+iy). But what about z^100? This is were polar represenation helps us, and to get into this representation we need the principle argument. I hope that helped.

How do you calculate root of any number using casio Fx 991MS calculator?

3 simple steps. i) press square root button ii) enter the number iii) hit "=" is it really that hard to figure out? ...... For complex numbers, refer to the definition of a complex number (abs(a)*exp(-j*angle(a)))1/2 = sqrt(abs(a))*exp(-j*angle(a)/2). therefore to do this on the casio fx-991ms try the following(assuming the complex number is stored in the ans): (sqrt(abs ans))[angle symbol]((arg ans)/2) added by Greg ......

If z equals a plus ib then show that arg conjugate of z equals 2pi -arg z?

If z = a + ib then arg(z) = arctan(b/a) Let z' denote the conjugate of z. Therefore, z' = a - ib Then arg(z') = arctan(-b/a) = 2*pi - arctan(b/a) = 2*pi - arg(z)
