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

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 $f(0)$. --Wrongfilter (talk) 19:07, 26 June 2011 (UTC)
