I tried to solve this Gaussian elimination algorithm problem (matrices) but for some reason when I plug in the x variables it doesn't work. The problem is:
Alright so the first thing I did was divide the 1st row by 1/3 (scaling). Then I made the entries below the first pivot equal to 0...

I am not sure how to solve this:
Given an augmented matrix, find conditions on a, b, c for which the system has solutions:
-1 -2 3 b
-1 -6 23 c
-3 2 4 a
so by Gaussian elimination, the matrix I ended up with is
1 2 -3 -b
0 4 -20 b-c
0 0 -35...
Hi. Suppose I have a function T(x,t), units are in Kelvins. I then do a convolution with a gaussian G(t), and the result is also in Kelvins. What are the units of the gaussian G(t)? Thanks.
I need a math guru to explain why and how the elimination method of solving simultaneous equations works ?
why do we add or subtract the two equations ?(I undertand in order to eradicate either term) but I need to know from the basics .
For that matter, how/why does the substitution method...
I am looking for a mathematical equation which is similar to the Gaussian normal distribution curve, but I need one which terminates at a finite x = X and not at infinity, ie, f(x \geq X) = 0, but, f(x \leq X) = a function which has a Gaussian shape-like curve.
Is there one such as this that...
Hi All,
I am just wondering whether there is any kind soul to help me out with the following problem:
If a gaussian beam is truncated by the circular aperture situated at the beam waist just before the entrance of a microscope objective lens, what should be the intensity distribution of...
Construct a spherical gaussian surface centered on an infinite line of charge. Calculate the flux through the sphere and thereby show that it satisfies gauss law.
I know how i can do it for a cylinder, but a sphere?
I know that the ends of the wire (one diameter) wil have zero flux at it's...
\psi (x)= \frac{1}{(\pi\Delta^2)^\frac{1}{4}} e^(\frac{i<p>(x-<x>)}{\hbar})e^(\frac{-(x-<x>)^2}{2\Delta^2}) as \Delta\rightarrow\infty should approach the plane wave \frac{1}{(2\pi\hbar)^\frac{1}{2}} e^(\frac{i<p>x}{\hbar}) up to a phase factor. I guess this happens by setting the...
So here is an example of what I am trying to do.
We know that div of an E field=p/eo
where p=charge density and eo=the permittivity of free space. This equation is expressed in MKSA units. In order to convert this into Gaussian units, we must multiply E by 1/sqare root of 4*pi*eo, and...
Hi,
Need help desperately!
I am trying to figure out the area under a gaussian cone by finding the integral of
2PIArEXP[-(r^2)/(2sigma^2)] dr
My supervisor thought it is
2PI [A sigma^2 EXP(-(r^2)/(2 sigma^2)] Between 0 and infinity
and he came up with the...
Nigel was polite enough to offer some discriptive views for extending awareness that I thought I too would indulge.
To raise the issue, to include the GR perspective, one has to retain some comprehension and viewing of the hyperdimensional realities when it comes to the geometries?
This...
A small copper spherical BB of radius a is located at the center of a larer hollow copper spherical shell of inner radius b and outer radius R. A charge of +q is on the small BB. The hollow copper shell has zero charge on it.
a) What is the electric field within the BB (for radii r<a)?
b)...
I'm having trouble showing the following relation:
E(exp(z)) = exp(E(z^2)/2)
where z is a zero-mean gaussian variable and E() is the avg
anyone can help?

A positive test charge is placed at the center of a spherical Gaussian surface. What happens to the net flux through the Gaussian surface when the surface is replaced by a cube of the same volume whose center is at the same point? or When the sphere is replaced by a cube of one third the volume...
hi,
I would like to know why dirak-delta function is used in autocorrelation in a way that the following is true:
<å(t)å(t')>=2Dä(t-t')
where å(t)is Gaussian white noise and D is the strength of the noise.

I have a new question:
"In applying Gauss's Law describe the types(s) of charge distribution for which (a) a spherical gaussian surface is useful and (b) a cylindrical gaussian surface is useful"
please help!
I am not sure of the spelling, but I heard of the 'gaussian quadature' (or quadrature). It was spoken, and was in a mathematical equation.
What the heck is it?
I have some doubts about it..in fact when you want to calculate an integral numerically..i always use gaussian integration but what would happen if i use this technique to calculate:
Int(0,1000)g(x)[f(x)]dx where [] means the floor function in fact it is a non-continuous function..would be...
