Let `f(x)=(x+1)/(x+2)` . If `int ( f(x)/x^2)^(1/2) dx=1/(sqrt(2))g((sqrt(2f(x))-1)/(sqrt(2f(x))+1))-h((sqrt(f(x))-1)/(sqrt(f(x))+1))` then

Let f(x)=(sqrt(x-2sqrt(x-1)))/(sqrt(x-1)-1).x then

Let f(x)=(sqrt(x-2sqrt(x-1)))/(sqrt(x-1)-1)*x then

Let f(x)=(sqrt(x-2 sqrt(x-1)))/(sqrt(x-1)-1) , then -

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

Let f(x) = (sqrt(x - 2 sqrt(x - 1)))/(sqrt(x - 1) - 1)x , then

int_( then )(x-1)(dx)/(x^(2)(sqrt(2x^(2)-2x+1)))=(sqrt(f(x)))/(g(x))+c
