There is a more elegant solution than parts, think about derivatives

You are not in position to make fun of the other anon.
I hope you were not the one suggesting parts too.

Other anon here btw.

x^2*sqrt(x^3+1)
=sqrt(x^4*(x^3 + 1))
=sqrt(x^7 + x^3)
so the integral is 2/3(x^8/8 + x^4/4)^(3/2)

no, the obvious answer is substituting $x^3+1=w$ and $\frac{1}{2} dw=x^2$ , and you literally type out shit like you're a 60 year old professor sending an email about erectile dysfunction pills that aren't working.

duckduckgo uses google results, makes them crappier and still feeds the info back.
sperging over how retarded it is and being proud to be globohomo on the other hand is worse than being a retard though. it's pure cancer.
