Double Integer with ln and e.?
I have a quiz soon and I'm comfortable with almost all of the material but I know something like this will be on the quiz. The problem is:
\int [0,pi/2] \int [0,(ln2)^2] r*e^sqrt(r^2) dr dtheta
I don't need a walkthrough, as I've already done the first integral. My book says the answer is: (2ln2 - 1)(pi/2)
What I ended with so far is:
\int [0,pi/2] r*e^r-e^r dtheta
My main question is, does r*e^r-e^r simplify to something easier to use? I was thinking the e^r-e^r would equal 1 but I'm not sure. Again, not looking for a walkthrough, just some clarification.
Sorry for the long post and thanks in advance for answering.

1 AnswerDo It Yourself (DIY)8 years agoStop seed from germinating?
Ok, I have a seed that I want to plant. I'm off at school and didn't think the seed would germinate, but it turns out that it did, and I won't have access to soil for a couple of weeks. The taproot is about 1cm long. Is there a way to pause the growing process or make it go very slow while keeping it alive until I get home?

2 AnswersOther - Games & Recreation1 decade agoHow come whenever I have a precognitive dream, my actual vision deteriorates?
I've been having precognitive dreams all my life, and it's not like it just feels like I've already lived some of what's happening, but I actually keep a dream journal and I have finished some of my friends' and my brother's sentences, and almost full conversation, and I'm able to know what people will wear, weather, people that I've never seen before in my life - I have seen in my dreams, so it's pretty much confirmed. But what I'm starting to notice, is that whenever I have a precognitive dream, my vision gets blurred little-by-little each dream. Is there anyone else that has experienced this or knows what it is? Any help?
