"Here is the full text of our trigonometrical poem:In days of old when knights were bold and dragons still breathed fireThere lived a knight, a clever knight, Sir Pythag-Oar EsquireHe had a lance, a sturdy lance, it measured thirteen feetHe had it with him just in case a dragon he should meet.But when he came to cross a bridge the guards they did implore:The longest thing allowed across is nine feet and no more.Sir Pythag puzzled long and hard; this problem was a questUntil he found a carpenter to make a wooden chestThe chest was made in record time; not long did Pythag waitThe chest could cross the bridge because 'Twas eight by eight by eightNow if you do the maths you'll see the diagonal is a lineOf length (worked out with 3D trig) roughly thirteen point nine.That's big enough to hold the lance with room to spare of course.But such a chest and the knight are too much for his horse."
