my father plays banjo professionally (also the fiddle, mandolin, guitar, and bass). It's a very unique instrument that is always distinguishable. I suppose it depends on the type of music you like, mainly it's used in Bluegrass/Old Time, but occasionally in Rock as well, such as David Gilmour's...

I need to be able to draw specific vectors, springs, dotted lines and whatnot. I'm sure I could do this in powerpoint or word, but it wouldn't reach the level of quality that this manuscript will require. I am essentially modeling coupled harmonic oscillations through hook's law. It is not...

I am working on a project for one of my physics courses and I require some specific illustrations to accompany the manuscript, which will be written in LaTeX. I believe Adobe Illustrator is capable of this, however having never used the program before, I'm not quite sure how to do this. The...

i'm missing something, cause i don't quite get it. Thus far, every time I have computed the jacobian, x was equal to something like u^2 + v and something similar for y. When you say evaluated at u=3, v=5, surly you don't mean with respect to because that doesn't make any sense, so what do you mean?

wouldn't the jacobian of a point just be zero? ie, dx/du = d3/du = 0 (etc..) ?

I apologize I guess I wasn't clear. We are given the coordinates in the uv coordinate system, and the first step towards a solution is to translate them into the xy coordinate system. But in all the examples I have done thus far, it is done through a function T(u,v)=(something, something), where...

Thank you for the Reply Dick. The Jacobian, as I understand it, is the determinate of the function X and Y "components" of the T(u,v) function. Evaluating the determinate creates: \frac{dx}{du}\frac{dy}{dv} - \frac{dx}{dv}\frac{dy}{du} but my misunderstanding comes into the fact that we do...

Homework Statement Using du=.01, dv=.01 find the aroximate area under the transformation of the square bounded by the lines u=3, u=3.01, v=5, v=5.01. Homework Equations T(u,v)=<au+bv, cu+dv> where a, b, c, and d make a square matrix. The Attempt at a Solution I am not sure...

The following has been extracted from a larger assignment, the details of which I do not believe are necessary. Anywho, here it is: \frac{1}{\pi}\int\frac{1}{x(\lambda-x)} e^{-(\frac{x-\mu_1}{\lambda-x})^2} e^{-(\frac{x-\mu_2}{x})^2} dx things to keep in mind: \lambda as well as \mu_1 and...

No I don't think so because the inside can only result in one of several cases, all of which contain only 0's, 1's, or imaginary numbers. anything else wouldn't make sense

bumping because i just now got the latex to display properly

This is a physics problem but I am having trouble factoring this matrix. Basically, there shouldn't be anything left inside the matrix except 0's, 1's, or i's (any of which can be negative). This seems like such an easy problem but I cannot find something that works. Any ideas? \frac {1}...

I think there's nothing quite like a good solid F to send the message "you're not working hard enough" to a student. I've received this message several times, and each time I react by doing whatever it is I need to do to do well in the class. In all the aforementioned classes which I have...

\int_{0}^{2 \lambda} \cos({\frac{kx}{2}}) \cos({nx}) dx I can't find my calc2 notes and it's killing me! This thing came up half way through the computation of the Fourier series of f(x) = A\cos({\frac{\pi x}{\lambda}})..and i can't remember how to do it! I am very aware of the trig identity...

Thanks OS..formatting is working now, still need help though.
