Sorry it is dy
I tried a substitution and it got very messy, ended up with y= sqrt( u-1/x). Hence I think I have taken the completely wrong route
Use Partial fractions:
Or you may make the substitution ,
Therefore the integrand now becomes,
This can be evaluated using standard forms.
I can integrate y/x^2 dy to get y^2/2x^2
Do I tackle the second integral by substitution?
I got du=2x^4y dy and my result for y again seems wrong as I got square root of -1/x^2 which you can't have
for the second one, use substution. and finish..
