" Find "int(x^(2)+1)/((x^(2)+2)(x^(2)+3))dx

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

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

Evaluate: int(x^(2)+(1)/(x^(2)))^(3)dx

Evaluate: int((x^(2)+1)(x^(2)+2))/((x^(2)+3)(x^(2)+4))dx

Evaluate : (i) inte^(x)((1)/(x)-(1)/(x^(2)))dx (ii) inte^(x)((1)/(x^(2))-(2)/(x^(3)))dx (iii) inte^(x){sin^(-1)x+(1)/(sqrt(1-x^(2)))}dx (iv) inte^(x)(tanx+logsecx)dx

Evaluate int((x^(2)-4))/((x^(2)+1)(x^(2)+2)(x^(2)+3))dx
