    use integration by parts to find the following:

    integral[t^3 . root(1+t^2) dt]
    with limits 0 and 2

    when i try it i just make it more complicated.
    what should i pick as my 'u' and 'dv/dt'?

    any help would be great.


    try u= t^2 and dv/vt= t(1+t^2)^(1/2)

    This would be better, can you see why?
