Need Help, Stuck on Calc 1 Homework!!

If this was stack overflow he'd now comment "Figured it out" but not explain it.

Well, at least you get to know that your obscure compiler error message that you've battled for days probably has a solution. You're bound to find it if you just give it another day or two... Maybe.

I think the closest analogy of the above that I've seen in math comes from a mysterious Math Underflow user named Cleo. Specifically, Cleo would repeatedly post exact solutions to tricky nonstandard integrals that Mathematica/Maple/etc couldn't handle, without explanation, hours or days before anyone else managed to solve them. Sufficient to annoy a portion of the site's users, apparently:

This style of answer is complete disrespect. This situation seems for me like this: Cleo found interesting problem, and solved it. He is lazy to write the solution but want to show how clever he is, so decided to post only the final result. The reference to the definition of golden ratio made me laugh. If OP asks question of such level he definitely familiar with this constant. Note that this is not a single example. ALL Cleo's answer are of this style, and even after polite ephasis that these answers is not what OP's wanted he continues to post only final results!

Answers such as this add no value to the site - simply stating a number out of thin air is not 'mathematics'.

I agree with Carl - What good does stroking your ego do in terms of teaching people how to solve these problems? Also, this doesn't even answer the question: "How [do I] evaluate this integral?"
