    Need help with Calculus problem

    Just a piece of advice, when given values for variables (i.e. x=2), leave the x in the original equation until all calculations and simplifications are done. She's learning the definition of a derivative, and it's better in the long run to see how variables are affected. Knowing and...

    Math Help!

    area = (1/2)base*height area = x base = x x = (1/2)x*h h = 2 theta1 and theta2 are the angles made with the base and each respective side sin(theta1) = 2/6 theta1 = 19.47 degrees sin(theta2) = 2/5 theta2 = 23.58 degrees x = 6cos(theta1)+5cos(theta2) x = 10.239 :beer:

    Feel like a physics problem, anyone?

    Easiest way to do it is to look at the changes in center of mass. Since Ricardo is the heavier of the two, we will treat his movement as positive and Carmelita's movement as negative. mRicardo*dRicardo-mCarmelita*dCarmelita = (mRicardo+mCarmelita+mCanoe)*dTotal 70*3.1-x*3.1 = (70+x+27)*.374...

    Water cooling kit for a first-timer

    I doubt the koolance system will provide any benefit over your tornado setup. The flow rate and the 1/4" diameter of the tubing really holds back serious improvements. Also the temperature reading for the exos is actually the water temperature, not the temperature of the cpu. Using any temp...

    Just took the GMATs

    Time to bring this thread back from the dead. For those that were asking, I am still waiting the official results, but unofficially a 730. My big complaint with it was that the question weren't at all like the practice questions from Princeton Review and the like. Aside from the formats, I...

    Has that law passed yet that allows you to keep your cell phone number between services?

    November 24th is the date. Some providers may charge a handling fee (like $1 a month for the number): AT&T, Sprint, and Nextel come to mind here. One company (I think is Verizon) is pressuring the others to waive the fee, as they do not charge anything for keeping your number and leaving their...

    Which tires to get

    Okay, I narrowed it down to two...Bridgestone S-03 or the Pirelli P-Zero Nero M+S. The all-season of the Pirellis make them really attractive not to mention the difference in price. The Pirellis would work out to be about $250 less than the S-03's.

    Poll: Warrenty issues. Who's to blame?

    Most postage carriers have a default insurance of $100, so you may be entitled to that, although I think it may have some expiration on it. If you are able to get the $100, take that and put it towards a new 19" Edit: so pretty much follow Rossman's advice
