int_(0)^((2)/(3))(dx)/(4+9x^(2))

The value of int_(0)^((2)/( 3)) (dx)/( sqrt(4-9x^(2))) is

Evaluate :int_(0)^(3)(dx)/(9+x^(2))

I=int_(0)^(2)((5-x)/(9-x^(2)))dx

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)(2x+3)dx

int_(0)^(pi//2)(dx)/((4+9cos^(2)x))

int(dx)/((4+9x^(2)))
