[x+c)],[(3)sqrt((1-cos x)/(1+cos x))]

tan ^(-1)(sqrt((1-cos 3 x)/(1+cos x)))

The value of lim_(x rarr0)(1)/(x^(2))sqrt((1-cos2x)/(1+cos2x))sqrt((1-cos x)/(1+cos x)) is equal to

tan ^(-1)(sqrt((1-cos 3 x)/(1+cos 3x)))

(v) tan^(-1)sqrt((1+cos x)/(1-cos x))

prove that cot^(-1)[sqrt((1+cos3x)/(1-cos3x))]

Derivatives of y = cos^(-1) sqrt((cos 3x)/(cos ^(3) x)) with respect to x , is

If x in (pi, 2pi) , prove that ((sqrt(1+cosx))+(sqrt(1-cos x)))/((sqrt(1+cos x)) -sqrt(1-cos x)) = cot(pi/4 +x/2)

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))}
