Find the domain Find the value sin2 210 degree tan 300 degre
Solution
we have given sin2(2100)tan(3000)cot(3150)
sin2(2100)tan(3000)cot(3150) =sin2(180+30)tan(360-60)cot(360-45)
=(-sin)2(30)(-tan(60))(-cot(45))
=(1/2)^2(-sqrt(3))(-1)
=(1/4)(sqrt(3))
=sqrt(3)/4
sin2(2100)tan(3000)cot(3150) =sqrt(3)/4
