hi, im trying to find the integral of x^3sqrt(1+x^4)dx(adsbygoogle = window.adsbygoogle || []).push({});

i set it up like this:

u=x^3 dv=sqrt(1+x^4)

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

and using uv-integralvdu i get

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

i know that in the end, the integral should equal1/6(x^4+1)^(3/2)but i dont know how to get there from where i stopped...

help?
