Cubic root of a complex number
WebFeb 13, 2014 · The cube roots of (, θ) are (3√, θ 3), (3√r, θ + 2π 3) and (3√ θ + 4π 3) (recall that adding 2π to the argument doesn't change the number). In other words, to find the cubic roots of a complex number, take the cubic root of the absolute value (the radius) and divide the argument (the angle) by 3. i is at a right angle from 1: i ... WebMay 23, 2011 · The cubic root of a negative number is just the negative of the cubic root of the absolute value of that number. i.e. x^ (1/3) for x < 0 is the same as (-1)* ( x )^ (1/3) Just make your number positive, and then perform cubic root.
