" 28."(cos x)/(sqrt(1+sin x))

int(cos xdx)/(sqrt(1+sin x))=2((sin x)/(2)+(cos x)/(2))+c

The value of int(sin x+cos x)/(sqrt(1-sin2x))dx is equal to sqrt(sin2x)+C(b)sqrt(cos2x)+C(c)+-sin x-cos x)+C(d)+-log(sin x-cos x)+C

If tanx=b/a then sqrt((a+b)/(a-b))+sqrt((a-b)/(a+b))= ........................... A) (2 sin x)/(sqrt(sin2x)) B) (2 cos x)/(sqrt(cos2x)) C) (2 cos x)/(sqrt(sin2x)) D) (2 sin x)/(sqrt(cos2x))

sqrt(cos 2x) + sqrt(1 + sin 2x) = 2sqrt(sin x + cos x) if

The number of integers in the range of the function f(x)=|4((sqrt(cos x)-sqrt(sin x))(sqrt(cos x)+sqrt(sin x)))/(cos x+sin x)

int(cos x-sin x)/(sqrt(8-sin2x))dx=sin^(-1)((sin x+cos x)/(a))+c

f(x)=sqrt(sin(cos x))+ln(-2cos^(2)x+3cos x+1)+e^(cos^(-1))((2sin x+1)/(2sqrt(2sin x)))

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
