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))) prove that (dy)/(dx)=(sin x)/(1-2y)

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

If y = sqrt(cos x^2 + sqrt(cos x^2 + sqrt(cos x^2 + ....oo))) , then (dy)/(dx) is equal to

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

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=

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