2. Firstly, you have assumed (part of) you conclusion. You are supposed to be showing that the only extremals are those satisfying , and , not just assuming it. I'll come back and have a look at the rest of it when I'm reasonably awake.

In that case there must be another way to go but here goes anyway.

If the end point satisfies then at x=b.

In this case .

It certainly seems to work and produces the solutions that they want which turn out to be y=x and y=2-x....I think.

How did you get tau? Also y(x) = x does not satisfy y(-1) = 3

because then .

With you have and . b=3.

With you have and . b=-1.
