<p>Let's play a little calculus game. Just post any calculus problem and provide the solution. I'll go first.</p>
<p>integrate : x^2 (e^x) dx</p>
<p>for this you need integration by parts, twice.</p>
<p>the final answer is: e^x( x^2 - 2x + 2) + C </p>
<p>Calculus in humanity's greatest achievement.</p>
<p>shhhhhhhhh</p>
<p>by the way, the formula for integration by parts is as follows:
integration sign: u dv = u v - integrationsign v du .
you just have to know how to pick the "u."</p>
<p>That's not a fun game...
:(
reminds me that I have to study calc</p>
<p>zante, if you need help, i will be glad to help you. just post any calc problem you have and i will be happy to provide a step by step solution. I recently won a state calculus contest, so i think i could help you out if u want.</p>
<p>Integral 1/(1+x^2)=arctan(x)</p>
<p>I have a fun one for you guys:
integral of e^(-x^2) from 0 to infinity.
This is a multivariable one.</p>
<p>That's why you're calculusboy...riight.
Thanks but it's that I don't know how to do it, I just don't feel like it.</p>
<p>Yuuuuuuuuuuuuuuuuuuuuuck. This reminds me of my much-neglected calculus homework, sitting in the den upstairs.</p>
<p>Somehow I always envisioned dens to be downstairs, like all dark and moody with a big tv and a fur rug thing. No? mmk</p>
<p>Well, ours upstairs from where I am - I'm in the basement right now (ours is finished). Our den is on our first floor. But my grandmum has the sort of den you're envisioning, with built-in dark wood bookcases and a gorgeous fireplace, and it's on the second floor.... I don't really know where I'm going with this, so few brain cells left after today.</p>
<p>Ahh that sounds pretty. And it sounds like your house is very big. Poor me, no space in new york =(</p>
<p>where in nyc?</p>
<p>who started learning about multiple integration today!! now THAT'S beautiful calculus</p>
<p>I haven't started yet. I think we start this week. Doesn't sound like fun, nuh uh.</p>
<p>what's your highest level of calc taken? everybody. . .</p>
<p>I'm in BC right now. School isn't very strong in math. I don't mind that much, I don't like it.</p>
<p>Haha, I love that everyone else is at integration right now. We're currently studying the use of the first and second derivatives to determine graph behavior. Then again, I am in Calc AB. Test tomorrow! Hehe, I'd say we were behind, but we're flying through the book. <em>shrugs</em></p>
<p>AB, but we were where you are now phil about 3 weeks ago. Of course, my teacher speaks no English and refuses to show derivatives when explaining work - really helpful when the mistake you made was IN your derivative.</p>
<p>Zante, my house isn't very big - about average size for my area. I don't think I'd make it in NYC, thought - not enough green space, I would think.</p>
<p>ohh that's why I need princeton. I need fresh air and grass...sighhh</p>
