`int_(0)^(1)(dx)/(x sqrt(x^(2)-1))`=

int_(0)^(1)(dx)/(sqrt(x^(2)-x+1))

int_(0)^(1)(dx)/(sqrt(x^(2)-x+1))

int_(0)^(1)(dx)/(sqrt((1-x^(2))))

int_(0)^(1)(dx)/(sqrt(1-x^(2)))

int_(0)^(1)(dx)/(sqrt(1-x^(2)))

Evaluate the following : int_(0)^(1)(dx)/(x+sqrt(1-x^(2))).

int_(0)^(1)(x)/(sqrt(1-x^(2)))dx=

int_(0)^(1)dx/(sqrt(1-x^2)

int_(0)^(1)dx/(sqrt(1-x^2)

If the value of the integral I=int_(0)^(1)(dx)/(x+sqrt(1-x^(2))) is equal to (pi)/(k) , then the value of k is equal to
