Question

If   w_1=2\,	ext{cis}\left(\dfrac{\pi}{6}ight)  is one solution to   w^2 = 4\,	ext{cis}\left(\dfrac{\pi}{3}ight)  then the other solution will be:

Answer

w_2=2\,	ext{cis}\left(-\dfrac{\pi}{6}ight)

Answer

w_2=2\,	ext{cis}\left(\dfrac{5\pi}{6}ight)

Answer

w_2=2\,	ext{cis}\left(-\dfrac{5\pi}{6}ight)
