Really having trouble being able to complete the first part of the question. Please send solutions
I've just seen your comment. So far, I've been able to show some of the relationship described in (i), but not all. The only thing I can easily provide here, unfortunately, is a low-quality picture of my rough work. Later on, if I am able, I will either translate this into an electronic document, or write more neatly.
I hope this helps as a start, and that this is not too late.
