There was a posted question Vector Graph that looked like a homework question. I answered it anyway because I often learn myself from such questions and I wanted to show a more elaborated development. Just before I started my posting I renewed the page to make sure it hadn't already been answered and that it was still there.

But after I made my posting the page disappeared and thus my answer never appeared. This is a bit irritating considering time involved. I'm wondering if the page was removed by the moderation team or the author. If it was by the author then perhaps he really was getting his homework done and then hiding it. If it was by the moderation team then I wonder why, or wish they had removed it sooner.
