" 11."int(dx)/(1-x^(2))

Evaluate the integerals. int ((1)/(1-x^(2))+(2)/(1+x^(2))) dx " on " (-1,1 ) .

Evaluate the integerals. int ((1)/(1-x^(2))+(1)/(1+x^(2))) dx " on " (-1,1) .

(i) int((x^(2) - 1)/(x^(2) + 1))dx , (ii) int ((x^(6)- 1)/(x^(2) + 1))dx (iii) int ((x^(4))/(1+x^(2)))dx , (iv) int((x^(2))/(1+x^(2)))dx

(i) int(dx)/(sqrt(11-4x^(2)))

Integrate the following int(dx)/(sqrt(11-4x^2)

Evaluate the following : int_(0)^(11//sqrt2)(sin^(-1)x)/((1-x^(2))^(3//2))dx.

int (dx)/(x^(2)+x+1)dx is :

int(e^(x))/((1+x)^(3))dx-int(e^(x))/(2(1+x)^(2))dx=
