So I was trying to update this question with a link to another well asked question here - I tried twice, but each time my answer did not appear- I am wondering if it is being checked because I asked the original question and already posted one answer...

...the idea was to post good examples of homework questions as separate answers, which is why I want to add a second answer.

Any idea what is going on? I typed out an answer twice and both hit post both times, but nothing seemed to appear....
