Examples of Using De Moivre's Theorem Calculator
Example 1: Calculating Powers of Complex Numbers
Consider the complex number z = 3 + 4i. Using De Moivre's theorem, we can calculate higher powers like z^3. Convert to polar form, r = 5 and \theta = \tan^{-1}(4/3). Apply the theorem: z^3 = 5^3(\cos(3 \times \tan^{-1}(4/3)) + i\sin(3 \times \tan^{-1}(4/3))). De Moivre's theorem calculator simplifies this computation.
Example 2: Finding Roots of Complex Numbers
To find the cube roots of z = 8, express z in polar form as 8(\cos(0) + i\sin(0)). According to De Moivre's theorem, the n-th roots are given by r^{1/n}(\cos((\theta + 2k\pi)/n) + i\sin((\theta + 2k\pi)/n)), for k = 0, 1, ..., n-1. The calculator provides outputs for each k.
Example 3: Multiplying Complex Numbers
Multiplying z_1 = 1 + i and z_2 = 2 + 2i using De Moivre's theorem starts with converting to polar form. Compute the product r_1r_2 and \theta_1 + \theta_2. Use the calculator to find r_1r_2\cos(\theta_1 + \theta_2) and r_1r_2\sin(\theta_1 + \theta_2), simplifying manual computations.
Example 4: Dividing Complex Numbers
For dividing z_1 = 5 by z_2 = 3 + 4i, express both in polar form. Calculate r_1/r_2 and \theta_1 - \theta_2. The De Moivre's theorem calculator helps find (r_1/r_2)\cos(\theta_1 - \theta_2) and (r_1/r_2)\sin(\theta_1 - \theta_2) correctly.
