Algebraický tvar komplexního čísla
Urči algebraický tvar komplexního čísla:
\large z_3 =5\left( \cos {\Large \frac{23\pi}{3}\large }+\text{i}\sin {\Large \frac{23\pi}{3}\large }\right)
\large z_3 = \Large \frac{5\sqrt{3}}{2}\large +\Large \frac{5}{2}\large \text{i}
\large z_3 = \Large \frac{5}{2}\large +\Large \frac{5\sqrt{3}}{2}\large \text{i}
\large z_3 = \Large \frac{5}{2}\large -\Large \frac{5\sqrt {3}}{2}\large \text{i}
\large z_3 = -\Large \frac{5}{2}\large -\Large \frac{5\sqrt{3}}{2}\large \text{i}
