`int(x^3dx)/((1+x^(4))`

int((x^(3)-1)dx)/(x^(4))

int((x^(3)-1)dx)/(x^(4)

Evaluate the following: int_0^1(x^3dx)/(1+x^4)

int((x^(3)-1)dx)/(x^(4)sqrt(6x^(6)-4x^(3)+2))(x>0)=(sqrt(6x^(6)-4x^(3)+P))/(Qx^(R))+c" then "P+Q-R" is equal to "

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

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

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

int(x^(3))/(x^(4)+1)dx

int(x+3)/((x+1)^(4))dx

int(x+3)/((x+1)^(4))dx
