Basically I have a question (2nd Screenshot) which I am trying to mirror with the below example, which has a written solution.

What I can't work out is how the solutions would differ given the boundary conditions, where would I put them in? Are the soutions to both problems the same?

Here is the worked example: http://i40.tinypic.com/3509kw2.png

Here is the new question: http://i41.tinypic.com/fn8c9t.png

(I would put them directly into this thread as images, but I don't know the resolution of peoples monitors and if they would scale ok)

Thanks
