Divide the angle by n and then add all possible multiples of 2 π n. (You should get n different angles.) Here, you take the fourth root of 16, which is 2. Then dividing the angle by 4 gives you π 4, and adding all possible multiples ...

WebMar 6, 2024 · It may be worth mentioning that the theorem is valid for fractions as well. As we are going to find cube roots, what we seek is (1 + i)1 3. For that let us first write 1 + i in polar form. As 1 +i = 1 +1i, r = √12 + 12 = √2 and θ = tan−1(1 1) = π 4. Hence 1 + i = √2(cos( π 4) + isin( π 4)) and therefore 3√1 + i = (√2)1 3 ...
