(sin((2 pi)/(7))+sin((4 pi)/(7)) -sin((6 pi)/(7)))/(sin((pi)/(7))sin((3 pi)/(7))sin((5 pi)/(7))) is equal to

The value of ((1+sin q))/(cos q) is equal to

The value of sin[cos^(-1)(-(1)/(7))+sin^(-1)(-(1)/(7))] is

The value of (sin 7 A + sin 3 A)/(cos 7 A + cos 3 A) is equal to

If sin q + cosecq =2, then the vlaue of sin ^(6) q + cosec ^(6) q is equal to

sin ((pi) / (7)) sin ((2 pi) / (7)) sin ((3 pi) / (7))

show that sin (2 (pi) / (7)) + sin (4 (pi) / (7)) + sin (8 (pi) / (7)) = (sqrt (7)) / (2)

The value of sin theta sin ((pi)/(3) - theta) sin ((pi)/(3) + theta) lies in (p,q) then p= and q=
