sqrt(4sin^(4)theta+sin^(3)theta)+4cos^(2)((beta)/(2)-(theta)/(2))

If theta lies in 3rd quadrant,then the value of the expression sqrt(4sin^(4)theta+sin^(2)2 theta)+4cos^(2)((pi)/(4)-(theta)/(2)) is equal to

Assertion (A) : If sqrt(4 sin ^(4) theta + sin ^(2) 2theta)+4 cos^(2) ((pi)/(4)-(theta)/(2))=2 , then theta lies in 3rd quadrant or 4th quadrant . Reason : (R) sqrt(sin^(2) theta) = sin theta

If ' theta ' is in the III quadrant then sqrt(4 sin^(4) theta + sin^(2) 2 theta )+ 4 cos^(2)""((pi)/4-(theta )/(2))=

sqrt(4cos^(4)theta+sin^(2)2 theta)+4cos^(2)((pi)/(2)+(0)/(2))

sin^(4)theta+cos^(4)theta=1-2sin^(2)theta cos^(2)theta

Let f(0)=sqrt(sin^(4)theta+4cos^(2)theta)-sqrt((cos^(4)theta)+4sin^(2)theta) ,then

Prove that sin theta+sin2 theta+sin4 theta+sin5 theta=4cos((theta)/(2))cos((3 theta)/(2))sin3 theta

If theta in ((pi)/(2), (3pi)/(2)), then the value of sqrt(4 cos ^(4) theta + sin ^(2) 2 theta) + 4 cot theta cos ^(2) ((pi)/(4) -(theta)/(2)) is .............. A) -2 cot theta B) 2 cot theta C) 2 cos theta D) 2 sin theta
