Question

answer part (iii)

Use de Moivre's theorem to help you answer the following question.
Remember that the argument of a complex numbers lies in the range - << T.
Important
When calculating the final answer in part (iii), you must use whole number values (integers),
otherwise the final answer will not be marked as correct.
Find the modulus and argument of -2-j correct to 3 decimal places.
Expected answer: 2.236
(i)-2-j| 2.236
(ii) arg(-2-j) = -2.678
places.
Hence find:
correct to 3 decimal places.
Expected answer: -2.678
radians, correct to 3 decimal
Expected answer: 718+11991 718 + 1199i
(iii) (-2-j)⁹
X
Input the anwer in a + bj form, with integer values for the real and imaginary parts.
