Root of 2i
Web1 - 1 + 2i = 1 + i^2 + 2i = (1 + i)^2 so answer is: +/- (1 +i) Other approach is to apply DeMovre’s law: 2^0.5 * (cos pi/2 + i sin pi/2)^0.5 also for 2^0.5* (cos 5pi/2 + i sin 5pi/2)^0.5 which is sqrt (2) (cos pi/4 + i sin pi/4) or sqrt (2) … WebFind the Equation Given the Roots square root of 2 , 2i. √2 2 , 2i 2 i. Roots are the points where the graph intercepts with the x-axis (y = 0) ( y = 0). y = 0 y = 0 at the roots. The root at x = √2 x = 2 was found by solving for x x when x−(√2) = y x - ( 2) = y and y = 0 y = 0. The factor is x−√2 x - 2. The root at x = 2i x = 2 i ...

WebApr 20, 2024 · To use De Moivre's theorem, we first write -2i is cis form: 0 - 2i has r = 2 and theta = 270. Then we take the cube root, which means the new result will have r^(1/3), and the angle (theta/3). This means r = cbrt(2) and theta = 90. This means that the answer is (cube root of 2)(cos90 + i*sin90), choice C. WebMar 5, 2024 · − 2 + i has norm (length) equal to ( − 2) 2 + 1 2 = 5 = 5 1 2 .
