I just found this site, looks like a great place. I'm looking for some help regarding a question in one of my assignments, I can't seem to figure it out with my material at hand.
That is the problem in question.
Now the problem is that I don't even know where to begin. If someone could just give me a hand in understanding what needs to be done to solve it that would be fantastic, I've been melting my brain trying to solve it. I'm sure the solution is quite simple, a few times I've ended up with k=1 being an answer, but I couldn't seem to prove that once I was finished.
