Webb3 nov. 2024 · This can be used to build an iterative formula which can be handled by a simple calculator, using that S 4 can be calculated by 4 times multiplying: S n e w = 4 5 S o l d + 108 5 S o l d 4 One can start even with a very rough guess, e.g. S o l d = 3. Then S n e w = 12 5 + 108 5 ⋅ 81 = 8 3 ≃ 2.67 which is already closer to S = 108 1 / 5 ≃ 2.55085. WebbTo evaluate the nth root of a complex number I would first convert it into trigonometric form: z = r[cos(θ) + isin(θ)] and then use the fact that: zn = rn[cos(n ⋅ θ) +isin(n ⋅ θ)] and: n√z = z1 n = r1 n ⋅ [cos( θ + 2kπ n) + isin( θ +2kπ n)] Where k = 0..n − 1 For example: consider z = 2 + 3.46i and let us try √z; z can be written as: institute of biology freie universität berlin
