Accepted Answer

$A = \left[ { - 2\pi /3,\pi /3\left] {,B = } \right[2,\;6} \right]$

Answer

$A = \left[ {\pi /6,\;5\pi /6\left] {,\;B = } \right[ - 2,\;2} \right]$

Answer

$A = \left[ { - \pi /2,\pi /2} \right],\;B = \left[ {2,\;6} \right]$

Answer

$A = \left[ { - \pi /3,\pi /3\left] {,\;B = } \right[2,\;6} \right]$
