" 10."(x-sin x)/(1-cos x)

1- (sin ^ (2) x) / (1 + cos x) + (1 + cos x) / (sin x) - (sin x) / (1-cos x) =

The minimum value of sin x((1-cos x)/(sin x)+(sin x)/(1-cos x)) is

(cos x)/(1-sin x)=(1+cos x+sin x)/(1+cos x-sin x)

if a=(1+sin x)/(1-cos x+sin x) then (1+cos x+sin x)/(2sin x) is

What is the value of {sin (x+y) -2 sin x+ sin(x-y)} /[cos (x-y) +cos (x+ y)-2 cos x] xx [(sin 10x- sin 8x)/ (cos-10x + cos 8x)] ? {[sin (x+y] -2 sin x+ sin(x-y)}//[cos (x-y) +cos (x+ y)-2 cos x]} xx [(sin 10x-sin 8x)//(cos10x + cos 8x)] का मान क्या है?

Prove that : (cos 9x - cos 5x)/(sin 17x -sin 3x)=- (sin 2x)/(cos 10x) .

(cos 9x - cos 5x)/(sin 17x - sin 3x) = (-sin 2x)/(cos 10x)

Prove that : (cos 9x - cos 5x)/(sin 17x - sin 3x) = (-sin 2x)/(cos 10x)

Prove that (cos 9 x-cos 5 x)/(sin 17 x-sin 3 x)=-(sin 2 x)/(cos 10 x)

Maximum value of cos x((cos x)/(1-sin x)+(1-sin x)/(cos x))
