Homework Statement
Find the integral of:
Homework Equations
x^2 . sinx dx (With upper and lower limits of pi and 0 respectively.)
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
Thanks.
