Answer:
please ask your teacher or any other people
Answer:
Step-by-step explanation:
Given complex number is:
To find:
Answer in rectangular form after using De Moivre's theorem = ?
i.e. the form (not in forms of angles)
Solution:
De Moivre's theorem provides us a way of solving the powers of complex numbers written in polar form.
As per De Moivre's theorem:
So, the given complex number can be written as:
Now, using De Moivre's theorem:
So, the answer in rectangular form is:
<span>Assume n begins with 1
an = 3n
a1 = 3*1 = 3
a2 = 3*2 = 6
a3 = 3*3 = 9
a4 = 3*4 = 12
Answer: 3,6,9,12</span>
