A) \[\frac{\pi }{4}\]
B) \[\frac{\pi }{3}\]
C) 0
D) \[\frac{\pi }{6}\]
Correct Answer: A
Solution :
\[{{z}_{0}}=\omega \]or \[{{\omega }^{2}}\](where co is a non-real cube root of unity) |
\[z=3+6i\,{{(\omega )}^{81}}-3i{{(\omega )}^{93}}\] |
\[z=3+3i\] |
\[\Rightarrow \] arg \[z=\frac{\pi }{4}.\] |
