    A Linear Diet Model

    Yes, I did edit my answer based off of Hurkyl's advice. Thank you HallsofIvy for checking it as well. Mitchell

    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...

    Separable Differential Equation

    Haha, I guess I will find out next year.

    Separable Differential Equation

    Thanks man. I guess I just wasn't thinking. BTW, I am very impressed by these forums. It is a great resource and there are many interesting things to read. Thanks, Mitchell

    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...

    Help Differentiating

    I need to differentiate D (the first equation). In this equation, there is an arcsin. I am not sure what to do about this. Well . . . just have a look: http://www.mlowery.0nyx.com/differentiate.jpg" If the browser says access denied, copy and paste the URL into a new browser window and it will...

    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)}
