WebNov 17, 2024 · Powers and Roots In this section we’re going to take a look at a really nice way of quickly computing integer powers and roots of complex numbers. We’ll start with integer powers of z = reiθ z = r e i θ since they are easy enough. If n n is an integer then, zn =(reiθ)n = rnei nθ (1) (1) z n = ( r e i θ) n = r n e i n θ WebUse Euler's formula: If the complex number is z = ρ e i θ = ρ ( cos θ + i sin θ) (polar coordinates; ρ, θ are reals), then: z α = ρ α ⋅ e i α θ In the particular case that α = 1 / n for a natural number n, as e i θ = e i ( θ + 2 k π) : z 1 / n = ρ 1 / n ⋅ e i ( θ + 2 π) / n
