int(x^(2)(x^(4)+4))/(x^(2)+4)dx

int(x^(4))/(1+x^(2))dx

int(x^(2))/(x^(4)-1)dx

int (x^(2))/(x^(2) +4) dx=?

int (x^(2))/(x^(2) +4) dx=?

int(x^(2)+2)/(x^(4)+4)dx=

int(x^2)/(1-x^4)dx

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

int (x^(2)dx)/(x^(4)+1)

Which of the following are true: I : int_(0)^(4) sqrt(x^(2)-4x +4)dx=4 II : int_(0)^(2) sqrt(x^(2)-4x+4)dx=2 III : int_(2)^(4) sqrt(x^(2)-4x+4)dx=2
