Hi everyone,

In order to solve this integral I would need to do a u substitution and then use integration of parts, right?

Int. 0-1 r^3/sq. 4+r^2 dr

t=r^3

tu=3r^2dr

r^2dr=tu/3

Then I would finish the u substitution and then do integration of parts, right? Or could I just do a u substitution?

Thank you
