Problem with Finite Integration

My question is regarded as below:

Pls help. I'm desperate in need of a solution.Torment273 (talk) 17:32, 26 June 2011 (UTC)[reply]

~~Partial integration~~ Integration by parts. Write the thing as

\int f(x)\sin x\,dx+\int f^{\prime \prime }(x)\sin x\,dx

. In the first term, set

u=f(x)

and

v^{\prime }=\sin x

, in the second term, set

u^{\prime }=f^{\prime \prime }(x)

and

v=\sin x

. You should end up with boundary terms only, from which you can read off

f(0)

That link doesn't go where you intend, I believe. Grandiose (me, talk, contribs) 19:09, 26 June 2011 (UTC)[reply]
