int_(1-sqrt(3))^(7+sqrt(3))(xdx)/((1+x)(1+x^(2))^(-))=

int_(2-sqrt(3))^(2+sqrt(3))(xdx)/((1+x)(1+x^(2)))=

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

The value of I=int_(-sqrt(3)/2)^(sqrt(3)/2)(dx)/((1-x)sqrt(1-x^(2))) is

int(sqrt(x))/(sqrt(1-x^(3)))

int(1)/(sqrt(3x+2)+sqrt(3x+1))

Evaluate: int_-(1/sqrt(3))^(1/sqrt(3)) (cos^-1((2x)/(1+x^2))+tan^-1((2x)/(1-x^2)))/(e^x+1)dx

Evaluate: int_-(1/sqrt(3))^(1/sqrt(3)) (cos^-1((2x)/(1+x^2))+tan^-1((2x)/(1-x^2)))/(e^x+1)dx

Evaluate: int_-(1/sqrt(3))^(1/sqrt(3)) (cos^-1((2x)/(1+x^2))+tan^-1((2x)/(1-x^2)))/(e^x+1)dx

If int_((-1)/(sqrt3))^(1//sqrt3)(x^(4))/(1-x^(4))cos^(-1)((2x)/(1+x^(2)))dx=k , then int_(0)^(1//sqrt3)(x^(4))/(1-x^(4))dx the value of k is equal to
