int_(4)^(9)(dx)/(sqrt(x^(3)))

int_(4)^(9)(dx)/(sqrt(x^(3)))

int_(0)^(a)dx/(sqrt(a^2-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)^(9)(dx)/(1+sqrt(x))

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

int_(0)^(a)(dx)/(x+sqrt(a^(2)-x^(2)))=(pi)/(4)
