is represented by point A.
is defined by this formula:![z^{n} = r^{n}\cdot [\cos n\theta + i\,\sin n\theta]](/tpl/images/1005/2504/4f176.png)
(1)
- Norm of the complex number, dimensionless. 
- Direction of the complex number, measured in radians.
- Power of the resulting complex number, dimensionless.![z^{2} = \frac{1}{2}\cdot \left[\cos \left(\frac{2\pi}{5} \right)+ i\,\sin \left(\frac{2\pi}{5} \right)\right]](/tpl/images/1005/2504/8aa16.png)
, then the following variables are:
(2)
(3)
and 
![z = \frac{\sqrt{2}}{2}\cdot \left[\cos \left(\frac{\pi}{5} \right)+i\,\sin \left(\frac{\pi}{5} \right)\right]](/tpl/images/1005/2504/fb46e.png)
