If `f(x)=(a+sqrt(a^2-x^2)+x)/(sqrt(a^2-x^2)+a-x)` where `a>0` and `x

If f(x)=(a+sqrt(a^2-x^2)+x)/(sqrt(a^2-x^2)+a-x) where a>0 then f'(0) has the value equal to

If f(x)=(a+sqrt(a^2-x^2)+x)/(sqrt(a^2-x^2)+a-x) where a>0 then f'(0) has the value equal to

If f(x)=(sqrt(x)+(1)/(sqrt(x)))^(2)," then: "f'(2)=

If f(x)=x sqrt(ax-x^(2)) for a>0, then f(x) is

If f(x)=sqrt(4-x^(2))+sqrt(x^(2)-1), then the maximum value of (f(x))^(2) is

If f(x)=sqrt(2x^(2)-6x+5)+sqrt(2x^(2)-40x+218) ,then the minimum value of f(x) is

If f(x)=(sqrt(a^(2)-ax+x^(2))-sqrt(a^(2)+ax+x^(2)))/(sqrt(a+x)-sqrt(a-x)) is continuous at x=0 then f(0)

The value of f (0), so that function f(x) = (sqrt(a^2-ax+x^2)-sqrt(a^2+ax+x^2))/(sqrt(a+x) -sqrt(a-x) becomes continuous for all x, is given by
