it's a straightforward problem.
just split up the integral into two pieces and integrate by parts the second one, once done, do it again and you'll be able to solve your problem.
Hi!
I have a problem here. I really hope someone will help me!
I have a function that could be derivated two times. The function is like this:
1) f(pi) = 2.
2) the definite integral from 0 to pi is ( f(x) + f ''(x) )*sin(x) dx = 5.
Find f(0).
(...by using integration by parts.)
(I'm really sorry that I still don't manage LaTeX, but I'll learn it as soon as possible...)
