16 cos5 θ=

  

  

  

  

If sin 6θ=32cos5 θsin θ-32cos3 θsin θ+3x, then x=

  

  

  

  

If sin 6θ=a cos5 θsin θ+bcos3 θsin3 θ+c cos θsin3 θ then a+b+c=

  

  

  

  

27 cos8 θ=

  

  

  

  

128 sin8 θ=

  

  

  

  

The last terms in the expantions of sin 8θ, sin 9θ respectively are

  

  

  

  

If cos 5θ=a cos θ+bcos3 θ+c cos5 θ+d, then

27. Cos3 θsin5 θ=

  

  

  

  

If 16 sin5 θ=asin 5 θ+b sin 3θ+c sin θ then

  

  

  

  

8sin4θ=

  

  

  

  

32cos4 θ.sin2 θ=

  

  

  

  

A= cos 200- sin 200, B= cos 1000+ sin 1000, C= cos 5π/6+ sin 2π/3 then the ascending order is

  

  

  

  

If cos  α+ cos β=0= sin α + sin β then cos(α - β)=
