The integral can be written as :

(1/2)*[

(x²+1) dx/(1+x⁴) -

(x²-1) dx/(1+x⁴) ]

Call the first integral , I₁and the second integral I₂

Divide by x²(numerator and denominator) in both the integrals.

If u need help in proceeding, plz reply.

Cheers.

just proceed till above...

then put x-1/x =t in 1s integral and x+1/x=t in 2nd....

(because their derivatives are present in numerators and denomenators can easily be found out....
