Question

Which point is represented by 6 times the quantity cosine 11 pi over 6 plus i times sine 11 pi over 6 end quantity question mark

Answer 1

`6\left[\cos\left( (11\pi )/(6) \right) +i\sin\left( (11\pi )/(6) \right) \right] \\\\\\ 6\left[\cfrac{√(3)}{2}~~,~-\cfrac{1}{2}i \right]\implies (3√(3)~~,~-3i) ~~ \approx ~~ \stackrel{ \textit{\LARGE S} }{(5.2~~,~-3i)}`
