This definition means that when going a distance of $\theta$ … 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. barang yang bersifat elastis https://clarionanddivine.com
