" 11."sqrt(cos x)

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)

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)

Simplest form of tan^(-1)((sqrt(1+cos x)+sqrt(1-cos x))/(sqrt(1+cos x)-sqrt(1-cos x))), pi lt x lt (3 pi)/(2) is:

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

If f(x)=|(10(sqrt(cos x)-sqrt(sin x))(sqrt(cos x)+ sqrt(sin x)))/(cos x+ sin x)| then number of natural numbers in the range of f(x) is

Domain of the function f(x)=sqrt(cos(sin x))+sin(x^(2)-1) is [-1,1][-2,2]c*[-pi,sqrt(2)]uu[sqrt(2),pi][-sqrt(2),-sqrt(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=

If pi
