Gjej z (complex solution)
z=\left(\frac{5}{2}-\frac{5}{2}i\right)e^{i\alpha }+\left(\frac{5}{2}+\frac{5}{2}i\right)e^{-i\alpha }
Gjej α (complex solution)
\alpha =-i\ln(\left(\frac{1}{10}+\frac{1}{10}i\right)\left(\sqrt{z^{2}-50}+z\right))+2\pi n_{1}\text{, }n_{1}\in \mathrm{Z}
\alpha =-i\ln(\frac{\left(-1-i\right)\sqrt{z^{2}-50}+\left(1+i\right)z}{10})+2\pi n_{2}\text{, }n_{2}\in \mathrm{Z}
Gjej z
z=5\left(\sin(\alpha )+\cos(\alpha )\right)
