1. The problem statement, all variables and given/known data If W is represented as the point shown in blue which of the other points satisfy z=Sqrt[w]? 2. Relevant equations 3. The attempt at a solution (The answer is Z2) I'm trying to study for a test and this is a practice problem and the book doesn't go into great detail about this sort of problem graphically but I think I have it figured out, just maybe not the best way of going about it. Because the power is 1/2 I imagine that means there are 2 Square roots of the complex number. Each varying by 2*pi I'm assuming W looks like its at 5pi/6 = 150 degrees just for reference. 150/2=75 degrees (150+360)/2=255 degrees I move 75 degrees from the x axis and there is no line there so I go to my next option. Then I move 255 degrees off the x axis and think maybe I hit where Z2 is located. Is my logic correct? Is there a more proper way of going about this? Or faster?
