# Thread: Differential Equations in Clinical Medicine

1. ## Differential Equations in Clinical Medicine

Group Project B, Chapter 2, Page 80 in Fundamentals of Differential Equations 8E.

Does anyone have Fundamentals of Differential Equations 8E?

I need help with Group Project B. It is very.. lengthy.

The book can be found on slideshare, or

Ecuaciones diferenciales 4ta edición - r. nagle, e. saff & a. snide?

If you understand the material and time management is the only problem, then I suggest you start working on this now. By the way, the provided page number is not for Group project B for the given link.

Who said anything about time management? I have a specific question about solving the linear equation in part (b), re equation (3). I'm looking for someone who has time to go to slideshare.net and look up the right book, who has time to read the whole problem, and has the knowledge to spare and share. Nice quotes

The solution of a first order linear differential equation of the form:

$\displaystyle \alpha \frac{dy}{dx} + f(x) y = r(x) \implies \frac{dy}{dx} + \frac{f(x)}{\alpha} y = \frac{r(x)}{\alpha} , \,\, r(x) \not\equiv 0$

where alpha is a constants, then we have:

$\displaystyle y= \frac{1}{\mu (x)} \left ( \int \mu (x) \cdot r(x) dx + C \right ) , \, \, \mu (x)= e^{ \int \frac{f(x)}{\alpha} dx}$

I took a glance at your problem, and it is just using different variables.

Ps. I went and looked up the problem because I am currently studying DE and wanted more practice, but someone else may not have. In the future please post all questions in the thread itself (show some initiative if you want help).
