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))}

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

If sin x + cos x = sqrt2 * c os x, "then : cos x - sin x = ...... A) sqrt2* cos x B) sqrt2* sin x C) sqrt2* (cos x +sinx) D)none of these

If pi

Prove that: (i)tan^(-1){(sqrt(1+cos x)+sqrt(1-cos x))/(sqrt(1+cos x)-sqrt(1-cos x))}=(pi)/(4)+(x)/(2)
