    7.a)ii)

    I end up with the relationship t_i=qt_i-1+pt_i+1 and using the conditions t_0=t_n=0 I just get t_i=0 which is clearly wrong.

    It's not entirely clear to me what your relationship is from how you've written it, but I going to assume that you've got ti=qti-1+pti+1

    This is very close, but it's missing something. Say n=2. Why doesn't your relationship work for t1?

    Edit: Part (b) is quite neat.
