Webz=cos ( (90+360k)/6)+isin ( (90+360k)/6) z=cos (15+60k)+isin (15+60k) We were given the constraint that theta has to be greater than 90 and less than 180. With the information we have now, that can be written as 90<15+60k<180. We are now thinking about what multiples of 60 will help us satisfy that inequality. 2. WebNov 20, 2024 · Select a Web Site.

WebJan 2, 2024 · z = r[cos(θ) + isin(θ)] is a solution to x3 = 1. Then 1 = z3 = r3(cos(3θ) + isin(3θ)). This implies that r = 1 (or r = − 1, but we can incorporate the latter case into our choice of angle). We then reduce the equation x3 = 1 to the equation 1 = cos(3θ) + isin(3θ) has solutions when cos(3θ) = 1 and sin(3θ) = 0.
