3. The Attempt at a Solution [/B]
I have uploaded two images, one of the problem and one of my solution. My problem is the following. When i calculate the ##dL## part my solutions differs from the one given in the book. Can someone take a look at the?
just a little edit: in the picture you see ##pldl##it is actually ##p_ldl##
