Algebraický tvar komplexního čísla
Urči algebraický tvar komplexního čísla:
\large z_4 =13\left( \cos {\Large \frac{60\pi}{12}\large }+\text{i}\sin {\Large \frac{60\pi}{12}\large }\right)
13\left(1+i\cdot0\right)=13
\large z_4 =13
13\left(-1+i\cdot0\right)=-13
\large z_4 =-13
13\left(0+i\cdot0\right)=0
\large z_4 =0
13\left(0+i\cdot1\right)=13i
\large z_4 =13i
