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

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

Let I=int_(1)^(3)|(x-1)(x-2)(x-3)|dx The value of I^(-1) .

Let I=int_(1)^(3)|(x-1)(x-2)(x-3)|dx. The value of I^(-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(2x+3)(x^(2)+3x-1)^(1/2)dx

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

Evaluate : (i) int(3x^(2))/((1+x^(6)))dx (ii) int(x^(3))/((x^(2)+1)^(3))dx (iii) (x^(8))/((1-x^(3))^(1//3))dx

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

Evaluate: (i) int((x^(3) + 4x^(2) -3x -2))/((x+2)) dx , (ii) int((x^(4) +1)/(x^(2) +1))dx
