2sin((pi)/8)sin((2pi)/8)sin((3pi)/8)sin((5pi)/8)sin((6pi)/8)sin((7pi)/8) = ?

The value of 2 sin (pi/8) sin((2pi)/8) sin((3pi)/8) sin ((5pi)/8) sin ((6pi)/8) sin((7pi)/8) is :

The value of sin(pi)/(14)sin(3 pi)/(14)sin(5 pi)/(14)sin(7 pi)/(14)sin(9 pi)/(14)sin(11 pi)/(14)sin(13 pi)/(14) is equal to

The numerical value of sin pi/18 * sin 5pi/18* sin 7pi/18 is.............

If a=sin\ pi/18 sin\ (5pi)/18 sin\ (7pi)/18, and x is the solution of the equation y=2[x]+2 and y=3[x-2], where [x] denotes the integral part of x then a= (A) [x] (B) 1/[x] (C) 2[x] (D) [x]^2

sin(pi)/(4)*sin(3 pi)/(4)*sin(5 pi)/(4)*sin(7 pi)/(4)=

Prove that: sin((pi)/(14))sin((3 pi)/(14))sin((5 pi)/(14))sin((7 pi)/(14))sin((9 pi)/(14))sin((11 pi)/(14))sin((13 pi)/(14))=(1)/(64)
