@JessePFrancis Perhaps there is some (very small) difference between the two posts. But they are about the same exercise and one of them has accepted answer, so I think the OP is satisfied with the answer they got. For these reasons I considered closing as a duplicate a reasonable idea.
Even if somebody thinks they should not be closed, there should be at least link from each of them to the other one. (So that people do not waste time writing down things that have already been explained.)
BTW thanks for finding the duplicate question Jesse. This helps to clean the site. (One unanswered question less.)
BTW is seems that the OP abandoned the older posts and concentrated only on the newer one. For example, she did not correct u(1)=u(1)=0 to u(-1)=u(1)=0 in both of them, only in the newer one.
@MartinSleziak Oh yes, I came across these while searching for extremals! And yes, been in the job of hunting down unanswered questions as a part of the Crusade of Answers, group!
I have a doubt: is there any way to pin point the questions which are unanswered, and is answered in comments instead? Off late many are pushed off the top list with answers in comments, which leaves it unanswered!
I have noticed, of late, people providing answers/copious hints to the question in comments instead of actually adding an answer on their own.
Other people might choose not to answer, as the question has already been answered, and it might offend the person who commented with the answer. In tim...
@MartinSleziak yes! like this ( answers:1 isanswered:no hasaccepted:no closed:no ) search query in Crusade of Answers! Some way to pin point unanswered questions with "That solves my problem" or "Thank you" in comments
For example, this question had the answer in comments, (though no thank you-s), I just had to quote that comment in answer (CW), pushing it out of unanswered queue!
