Now, because the question has a number of mathematical symbols, I have created one large image rather than inserting lots of tiny images into the text, that never align properly anyway. If the text appears unclear in your browser then just click on any part of it and you can view a larger, clearer version. If the question itself is unclear, then that's an altogether different problem!

Have fun! And share this with your friends.

As always, full solutions please.
