Thread: Triple Integral - Volterra equation problem

Here's the problem:

y'''(x) = f(x) subject to the conditions y(0)=y(1)=y(2)=0.

Perform three integrations to show that a solution may be written

y(x) =

Determine L(x,t).

My attempt:

After triple integration I get

y(x) =

where A and B are constants which I've determined but won't write here.

Anyway, I don't see how this can be converted to find the desired L(x,t)
(I'm assuming my triple integration is correct- I think it is)

The form of your solution is correct, and if you have solve for A and B you are done!

I couldn't see the wood for the trees: the question just asked for a solution.
I just stick x=2 in.
