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

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 f(x)=sqrt(x^2-10 x+25) , then the derivative of f(x) in the interval [0, 7] is (a) 1 (b) -1 (c) 0 (d) none of these

If u=tan^(-1)(1/(sqrt(cos 2 theta)))-tan^(-1)(sqrt(cos 2 theta)) , then sin u=

If u=cot^(-1)sqrt(cos theta) -tan^(-1)sqrt(cos theta) then sin u=

If u=cot^(-1)sqrt(cos theta) -tan^(-1)sqrt(cos theta) then sin u=
