The value of `f(x)=(sin8x+7sin6x+18sin4x+12sin2x)/(sin7x+6sin5x+12sin3x)` is equal to

If 0 lt x lt pi, then (sin 8x + 7 sin 6x + 18 sin 4x + 12 sin 2x)/( sin 7x + 6sin 5x + 12 sin 3x) equal to a) 2 sin x b) sin x c) sin 2x d) 2 cos x

Find the value of X if sinx +sin7x =sin4x

(sin7x+6sin5x+17sin3x+12sin x)/(sin6x+5sin4x+12sin2x)=

If 0 lt x lt pi then ( sin 8x + 7 sin 6x + 18 sin 4x +12 sin 2x ) /( sin 7 x + 6 sin 5x + 12 sin 3x ) =

sin2x + sin4x + sin6x=0
