I practiced the even number questions in my textbook. The book does not list the answers for even numbers in the back. Only odd number answers are given. I am only going to give you my answers for 2 questions. Can you please check to see if I correct?
1) Find the complex cube roots of -8 - 8i.
My Answers: d = degrees
First root = 16^1/6 (cos 75d + i sin 75d)
Second root = 16^1/6 (cos 195d + i sin 195d)
Third root = 16^1/6 (cos 315d + i sin 315d)
2) Find the complex cube roots of -8.
First root = 2(cos0d + i sin0d)
Second root = 2(cos 120d + i sin 120d)
Third root = 2(cos 240d + i sin 240d)
Am I right? If not, can you help me by providing the steps that will guide me through?
