If y= sqrt(cos x) + sqrt (cos sqrt (x)),then (dy)/(dx)

The range of the following function is f(x)=sqrt((1-cos x)sqrt((1-cos x)sqrt((1-cos x)sqrt(cdots oo))))(0,1)(b)(0,(1)/(2))(c)(0,2)(d) none of these

If y=sqrt(cos x+sqrt(cos x+sqrt(cos x+...oo))) prove that (dy)/(dx)=(sin x)/(1-2y)

If y= sqrt (cos x + sqrt (cos x + sqrt (cos x + ......oo))) , then show that dy/dx = frac{sin x}{1-2y}

If y=sqrt(cos x+sqrt(cos x+sqrt(cos x+......oo))) then prove that (dy)/(dx)=(sin x)/(1-2y)

If y=sqrt(cos x+sqrt(cos x +sqrt(cos x+....oo))) " then prove that " dy/dx = sinx /(1-2y).

tan^(-1){(sqrt(1+cos x)+sqrt(1-cos x))/(sqrt(1+cos x)-sqrt(1-cos x))}

If the function f(x)=(sqrt(1+cos x)+sqrt(1-cos x))/(sqrt(1+cos x)-sqrt(1-cos x)) If the value of f((pi)/(3))=a+b sqrt(c) then a+b+c=
