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

underset(x to 0)"Lt" (sin 7x-sin 5x+sin 3x-sin x)/(sin 6x-sin 4x+sin 2x)=

sin2x + sin4x + sin6x=0

The value of 8x+7sin6x+18sin4x+12sin2xf(x)=(sin8x+7sin6x+18sin4x+12sin2x)/(sin7x+6sin5x+12sin3x)

(sin x) / (sin2x sin3x) + (sin x) / (sin3x sin4x) + (sin x) / (sin4x sin5x) + .... n

int(sin x+4sin3x+6sin5x+3sin7x)/(sin2x+3sin4x+3sin6x)dx=

The value of 2 sin 3x cos 2x is equal to .............. A) sin 5x+ sin x B) sin 3x+ sin x C) sin 7x + sin x D) sin 4x + sin x

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 ) =

Prove that sin7x + sin5x + sin3x + sinx = 4cosx cos2x sin4x

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
