Essay

Write the product $$z _ { 1 } z _ { 2 }$$ and quotient $$z _ { 1 } / z _ { 2 }$$ , if $$z _ { 1 } = 8 \left( \cos \frac { 11 \pi } { 6 } + i \sin \frac { 11 \pi } { 6 } \right)$$ and $$z _ { 2 } = 2 \sqrt { 3 } \left( \cos \frac { n } { 3 } + i \sin \frac { n } { 3 } \right)$$ in polar form.
