Fundemental lemma of the calculus of variations
I think I have it. The description in wiki is a little limited (alternatively my imagination is limited :smile:) so by a little mixing and matching of proofs I think I have found it. Thanks anyway.- TooFastTim

Fundemental lemma of the calculus of variations
Homework Statement Hi, I've been revising the calculus of variations and using the wiki entry on the euler lagrange equation (http://en.wikipedia.org/wiki/Euler-Lagrange_equation) as a reference. Scroll down and you'll see: Derivation of one-dimensional Euler–Lagrange equation. Expand this...- TooFastTim

Graduate Laplace transform of function with independent variables OTHER than time
Correct, I was thinking of an application analogous to the original application of the Fourier seies which was (I'm open to correction here) heat transfer along a beam, so the independent variable in that case would have been length along the beam. I'm sure somebody has used the Laplace...- TooFastTim

Graduate Laplace transform of function with independent variables OTHER than time
Yeah, but most (the vast majority) of the literature uses time as the independent variable. I was looking for examples that do not.- TooFastTim

Graduate Laplace transform of function with independent variables OTHER than time
Hi all Conventionally we used to seeing the Laplace transform applied to problems that use time as the independent variable, can anybody point me at some examples that do not use time as the independent variable? Thanks Tim- TooFastTim

Undergrad What is Potential Energy? Learn About V=(1/2)*m*w2*x2
Just reading up on lagrangeans and I came across an expression for potential energy I'd never seen before: V=(1/2)*m*w2*x2. I suppose all you physics majors are familiar with it. But what is it and where can I find out more?- TooFastTim

High School Plane after take-off to heavy to climb to cruising altitude?
The bit that amazes me about this question most is that Al Italia are stil flying and not being bought out by a rival airline.- TooFastTim

Undergrad Eliminating noise from Excel Data
You could try using a sliding window filter. SWF are essentially finite impulse response filters and are pretty good at removing unwanted noise. Alternatively you could try a Kalmann filter.- TooFastTim
