I'm having difficulty with this, trigonometic substitution won't work, neither would integration by parts...(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int_{0}^{\infty} \frac{y^2}{1+y^4} dy[/tex]

ETA:

doing trigonometric substitution with [tex] y^2 = tan\theta[/tex], I would get

[tex]\frac{1}{2} \int_{- \frac{\pi}{2}}^{\frac{\pi}{2}} \sqrt{tan \theta} d\theta [/tex]
