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

int ((2x^(e)+ 3)dx)/((x^(2) -1)(x^(2) + 4)) = k log ((x+1)/(x-1)) +k (tan^(-) ((x)/(2))) , then k equals :

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

Integration by partial fraction : If int (2x^(2)+3*dx)/((x^(2)-1)(x^(2)-4))=log((x-2)/(x+2))^(a)((x+1)/(x-1))^(b)+c then the value of a and b are ...... Respectively.

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

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

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

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

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

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

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