int((1-x^(2))dx)/(x(1-2x))

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

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

(5) int(x^(2)-1)/(x(2x-1))dx

(5) int(x^(2)-1)/(x(2x-1))dx

If int_0^1 ((1-x^2)dx)/(1+x^2+x^4) =aInb then,

9*int((1-2x)dx)/(sqrt(1+x-x^2))

(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

int(x^(2)+x+1)/(x^(2)-x+1)dx
