(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the integral of:

2. Relevant equations

x^2 . sinx dx (With upper and lower limits of pi and 0 respectively.)

3. The attempt at a solution

Integrating for the first time:

-x^2 . cos x + 2 [integral of] x . cosx dx

After integrating a part of my first integration:

-x^2 . cosx + 2xsinx + 2cosx

----------------------------

I used the method of integration by parts where u = x^2 and dv = sinx.

I don't really need the final answer, i just want to see where i am going wrong with the actual integration.

Anything with trig in it seems to completely throw me :grumpy:

Thanks.
