WebJul 28, 2024 · Find the fifth roots of 243 (cos 240° + i sin 240°) z ⁿ = rⁿ (cos.n.Ф + i.sinn.Ф). with k = 1,2,3,..,n-1. Note that ⁵√ (243) = 3. The best way to find a root is to get the root of the coefficient, then divide the angle by what root you want for the first one, then add 360/root to get each additional angle until you have all the roots. WebApr 19, 2024 · Matheng. use De Moivre's Theorem: ⁵√ [243 (cos 260° + i sin 260°)] = [243 (cos 260° + i sin 260°)]^ (1/5) = 243^ (1/5) (cos (260 / 5)° + i sin (260 / 5)°) = 3 (cos 52° + i sin 52°) z1 = 3 (cos 52° + i sin 52°) ←← so that's the first root. there are 5 roots so the angle between each root is 360/5 = 72°. then the other four ...
