Hello! I'm a student from Kiev Polytechnic Institute, Ukraine. This summer I'm coming to the US for Work and Travel Cultural Exchange Program. Can anyone tell me if it is possible to find any kind of an internship or a temporary job related to physics, if so where can I apply for such a...

how come that I can take xS'\approx-3/2? I've calculated c(x) as you proposed: c(x)=3/2lnx+C1x^2+C2x+C3. So the final form is like f(x)\approx Ae^{c(x)} Daymn... i don't understand that WKB method...

Hi! I need to solve a differential equation for my bachelor's project. Rather i need to find a asymptotic solution, when x goes to infinity. That eq. describes Alfven Waves in rotating inhomogenious plasmas, accounting effects of finite larmor radius. So the equation is as follows...

In most REAL cases (not sample problems) maple sucks

sry... mistake with the right forum for the thread. Move it please to Diff. Eq. forum. thx

http://djvu.504.com1.ru:8019/WWW/888e7f7367ba8f0f0eb381b0cadf0de4.pdf p. 230 change the dependent variable from y(x) to u(y)=y'(x). Then the Order of the eq. will lower by 1. Note: NOT u(x)=y'(x), BUT u(y)=y'(x)

Hi community :P Need some help with a differential Equation: 3/2y(x)+xy'(x)+y'''(x)=0 actually I'm looking for an asymptotic solution, when x -> infinity. I made some research about that Eq. and here what i have found: 1 guy found an asymptotic sol. for a more general eq...
