int_(0)^(2)(dx)/(sqrt(4-x^(2)) =?

int_(0)^(4)(dx)/(sqrt(4-x))

int_(0)^(a)(dx)/(sqrt(ax-x^(2)))

Evaluate the following definite integrals Let int_(0)^(1)(dx)/(sqrt(16+9x^(2)))+int_(0)^(2)(dx)/(sqrt(9+4x^(2)))=ln a

int_(0)^(4)(dx)/(x+sqrt(x))

int_(0)^((1)/(2))(dx)/(sqrt(4-x^(2)))

int_(1)^(2)(dx)/(sqrt(x^(2)+4x+3))

int(dx)/(x sqrt(x^(2)+4))

int(dx)/(x sqrt(x^(2)-4))

int_(0)^(2)x^(2)sqrt(4-x^(2))dx=
