    News Presidential Candidates 2008

    I am not a big fan of Brownback or Tancredo either, but Senator Paul stood out in my eyes more than those two. He ran as a Libertarian in '98 and came in 3rd. There also seems to be a Libertarian movement beginning to catch on. I think he'll turn out to be much more successful than was expected.

    Circuit Question

    When the switch closes, it creates a node between the four resistors. The resulting parallel connections will be in series with each other - the way you calculated it. :smile:

    Hours Allotted for Study

    Wow, thanks for the input guys (although I had to wait a while for the forums to come back up :rolleyes: . . . j/k, the guys at PF do a great job). I am not planning on "counting hours", I just wanted the heads up from a few people who have been through it (more is always welcome). I'm sure...

    Hours Allotted for Study

    I am definately not expecting to keep my week-ends completely free. However, I would like to keep Saturdays free and preferably Friday nights as well. I just didn't schedule anything for the week-end so that any additional studying I do on the week-end will be on top of the 20 hours during the...

    Modern Digital System Design

    I will be taking Modern Digital System Design during the Fall 2006 semester at Texas Tech University. As I am an incoming freshman, I have nobody to consult about this class. If someone could please tell me what this class is about, what I should be expecting, and/or what I can do to prepare for...

    Potential Difference Help

    Here is the question: A parallel-plate capacitor is made of two circular plates, each with a diameter of .0025m. The plates of this capcitor are separated by a space of .00014m. What is the potential difference between a point midway between the plates and a point that is .00011m from one of...

    A Linear Diet Model

    Well my new answer seems more logical :) Thank you so much Hurkyl.

    A Linear Diet Model

    I am working on solving a linear diet problem. I am given a differential equation. The problem basically requires me to solve the D.E., then plug 'n chug. I have gone over the solution to the D.E. over and over again. A fellow calculus student has also looked over the math and cannot find the...

    Advice wanted: online chat - text or voice

    I personally use Ventrilo. If you have high-speed internet, you can use your own computer as the server. When I want to chat, I simply startup the server software. This then allows myself and those with whom I wish to talk to connect using the client software. It is quite simple. The initial...

    Separable Differential Equation

    Hello, Yes, this is for a class - but it is simply a high school homework assignment. I am solving for v. (This is only part of the homework problem, BTW). http://mlowery.t35.com/AP_4_1a.jpg [Broken] My question is particularly concerned with the last two lines. On the final line, is the -64/5...

    Implicit Differentiation

    Hehe, how'd that "y" sneak by me? :grumpy: Thanks for the help. Yeah mezarashi, I am not quite familiar with the notation you used (I just started using the dy/dx notation last week). Thanks, Mitch

    Implicit Differentiation

    Yes, that is what I originally did. The thing is, this is a multiple choice question. Of the choices, the only answers close to this are: (Please don't think I am using this forum for answers. I just believe none of the choices are correct). A) \frac{4x^3}{-sin(y^2)} B)...

    Implicit Differentiation

    Find \frac{dy}{dx} given cos(y^2) = x^4 Is this correct: 1. cos(y^2) = x^4 2. -sin(y^2) \times 2y \frac{dy}{dx} = 4x^3 3. \frac{dy}{dx} = \frac{4x^3}{-2sin(y^2)}

    How to find resultant for 3 given vectors

    I am a senior in physics, so I'm not exactly an expert. But I have already completed that chapter. Simply add all of the Y's to find the y-component of Vr (V_ry). Next, add all of the X's to find the X component of Vr (V_rx). Then: V_r = \sqrt{V_ry^2 + V_rx^2} Correct me please if I am...

    Check my answer please (factoring)

    My teacher assigned us this problem (it is for extra credit, but I'll take what I can get): P = a(b^4-c^4)+b(a^4-c^4)+c(a^4-b^4) My work: 1. P = a( (b^2)^2 - (c^2)^2 )+b( (a^2)^2 - (c^2)^2 ) + c( (a^2)^2 - (b^2)^2 ) 2. P = a[ (b^2+c^2) (b+c) (b-c) ] + b[ (a^2+c^2) (a+c) (a-c) ] + c[...

    Simple problem. Please check my answer?

    Thanks. I was having trouble grasping the concept that we assume the oil molecules are perfect spheres. I was thinking, you know, complex branch-chain alkanes and stuff. So even when I did get the correct calculation, I was unsure whether my assumption was valid. Additionally, I found one...

    Simple problem. Please check my answer?

    The Problem One liter (1000 cm^3) of oil is spilled onto a smooth lake. If the oil spreads out uniformly until it makes an oil slick just one molecule thick, with adjacent molecules just touching, estimate the diameter of the oil slick. Assume the oil molecules have a diameter of 2 x 10^-10 m...
