Rsi 2012

<p>look at previous threads and work backwards from acceptees to their respective chance posts :smiley: iluvmathstrategiesappliedtorealworldproblemsthatreallymatter :D</p>

<p>I know the essays are incredibly importaint to the application, and Iā€™m curious to see what others wrote. Would anyone who has been accepted mind sending me a copy of theirs? :)</p>

<p>does RSI give lesser states an advantage over bigger state? (such as midwest, dakotas, wyoming, etc.)</p>

<p>not sure what you mean by ā€œadvantageā€, but states like cali normally get multiple people in, though smaller midwestern states donā€™t necessarily always have somebody qualify.</p>

<p>I think it really is a meritocracy.</p>

<p>Great website! Iā€™ll recomend it to my friends. Did you make it all by yourself? This may not be good news for us. It looks like there are only 49 spots left. :(</p>

<p>@ratdeno: you are an inspiration to people like me and others who love math, thank you for those amazing words on your website.</p>

<p>:} Thanks for your encouragement @darksigma and @RSIuser! Yep, I made it by myself for a presentation at school.</p>

<p>@ratdeno, from which state do you hail?</p>

<p>@darksigma, Iā€™m from Wisconsin, but I really donā€™t think Iā€™m going to get in. What state are you from?</p>

<p>California Bay Area >.< stiff competition around these parts</p>

<p>Looks like it. You seem very involved, though, and I bet your stats and essays were pretty impressive :slight_smile: Good luck!</p>

<p>Hey guys,
My school told me that it doesnā€™t have updated official transcripts until late January, so I had emailed CEE about it (before Jan 6th) and Maite told me I could send my official transcript with certified test scores later. However, I found out today that transcripts actually wonā€™t be available until the 1st or 2nd week of February (I guess they needed more time?), and also that my school doesnā€™t send test scores. They expect us to send scores through collegeboard, but RSI doesnā€™t have a code or anything right? How can I send certified score reports then if my school doesnā€™t send them? Iā€™m allowed to put copies of my scores in the envelope that the school sends with the official transcript-- will that be enough to count as ā€œcertifiedā€? However the copies of my SAT scores would say ā€œunofficialā€ on it.
Any help would be greatly appreciated!!! Thanks in advance!!!</p>

<p>Hey guys, this is a little bit off topic but I have a calculus problem that I really need answered. It was the only problem on my calc final that I missed and after 30 minutes of discussing my teacher wasnā€™t able to convince me about the correct answer. Iā€™ll probably go to my physics teacher with it as well, but just wanted to ask you guys first.</p>

<p>Hereā€™s the problem:
ā€œFind the work done in filling an upright cylindrical tank of radius 3 feet and height 10 feet with a liquid that weighs 50 pounds per cubic foot. Assume that the liquid is pumped into the tank through a hole in the bottom of the tank.ā€</p>

<p>Since were finding work we know that we must integrate force with respect to distance. I approached this by making a graph with force on the y-axis and distance on the x-axis. For the force, itā€™s pretty straightforward; we start with the volume of the tank times the weight per cubic foot. This gives us 4500pi. The main dilemma I have is what to put for distance. My calc teacher said to simply put the height of the cylinder on the x-axis, but I donā€™ think thatā€™s correct. This is because gravity is not taken into account in these types of work problems. Therefor it should be volume alone that determines the amount of work required to pump the water in regardless of height. For example, if we had a cylinder of the same volume but of a lesser height, if we disregard gravity then it should take the same amount of work to pump the liquid into that cylinder compared to this one.</p>

<p>Any thoughts and suggestions would be greatly appreciated!! Sorry for the long post, but I really want to understand this problem, and possibly get 100% in the case my calc teacher made an error.</p>

<p>I think that your mistake is that you did not take gravity into account. It does actualy have to be taken into account in this problem. To see that this is true, consider a cylinder with negligable hight and a very large base, so the cylinder still has volume. Then to fill the cylinder, the water does not have to move upword againts gravity. All of the liquidā€™s movement is perpindicular to the force of gravity and therefor the term F*ds=0 and no work is required to fill the cylinder. Therefor the work required to fill a cylinder does not depend only on its volume.</p>

<p>@ratdeno15, you donā€™t thing that you will get in? Did you write a poor set of essays or have a serious flaw in your application? If you donā€™t you may have a good chance from what Iā€™ve seen.</p>

<p>@ ratdeno: I can only hope that the admissions people see it through the same lens lol</p>

<p>@RSIuser, I understand the whole notion with gravity. However, I donā€™t feel these types of work problems ever incorporate the force of gravity. Consider this for example: A box weighing 20 pounds is pushed across a room for 20 ft. Now consider this: a 20 pound box is lifted 20 ft. high. Obviously we know that it would require a lot more work to do the latter task. However, it is not accounted for in these problems and the answer in both scenarios would be 400ft-lbs. Thatā€™s what I mean when I say that gravity is not accounted for in traditional work problems.</p>

<p>If you say so. The only time Iā€™ve ever done physics problems is in physics class, and I feel that it should stay that way. :)</p>

<p>And just to clarify, I donā€™t dislike physics. I just feel that one should learn physics in physics class and math in math class. It just makes things confusing when a math book tries to teach physics.</p>
