Inversion Definition and 123 Threads

we keep a clock in front of the mirror,if lateral inversion occurs,what will happen?

Homework Statement Find the inverse laplace transform of In(1+1/s) Homework Equations The Attempt at a Solution Using the complex inversion theorm, and the sum of the residues. The only residue is at s=0. and it is a simple pole of degree one. Therefore lim(s approaches...

What is the mean of " Effective logic inversion " ? Because I can't understand this qustion, " Describe briefly why there is an Effective logic inversion between logic level from a TTL IC and the LED load it drives? "

Anyone have opinions on teeter hang ups? Below is what they claim: http://www.teetertv.com/

Hello, I bought a Meade NGC-70TC refractor telescope and the image is inverted left-to-right. Is that normal? A google search didn't yield any answers.

Hi, I'm trying to prove that X=(X_{t})_{t\geq0} is a Brownian Motion, where X_{t} = tB_{1/t} for t\neq0 and X_{0} = 0. I don't want to use the fact that it's a Gaussian process. So far I am stuck in proving: \[ X_{t}-X_{s}=X_{t-s} \quad \forall \quad 0\leq s<t \] Anyone has any ideas?

The parts of this problem form a proof of the fact that if G is a finite subgroup of F^*, where F is a field (even if F is infinite), then G cyclic. Assume |G|=n. (a) If d divides n, show x^d-1 divides x^n-1 in F[x], and explain why x^d-1 has d distinct roots in G. (b) For any k let \psi(k)...

This is an idea I have about when everything is the exact opposite of itself. The post sounds very philosophical, but I am wishing to apply it to physics or in general sciences. Originally from: http://jefflifewah.blogspot.com/ This is a very bad write up. Hope you guys get the main ideas...

Homework Statement Suppose A is an invertible mxm matrix, B is an invertible nxn matrix, and C is an arbitrary mxn matrix. Is the matrix M = A|C ---- O|B invertible? Solve with proof. Hint: Use block multiplication. Note: I'm not quite sure how to draw this matrix on the forums. It...

What is the criteria to know whether a function may be inverted into an elementary functional form?

[SOLVED] inversion layer in a MOS Hello, I have some questions about MOS devices, and CCD In a MOS or MIS after applying a voltage on the metal, the valenceband and the conduction band bend downwards (in the usual band diagram) when a positive voltage is applied. (p-type semiconductor)...

But..is really so easy? (Möbius inversion), let be F(x) and G(x) functions F(x)= G(ax)+G(2ax)+G(3ax)+... for n=,1,2,3,4,5,... a is a fixed real number. then G(ax)= \sum_{n=1}^{\infty}\mu (x) F(nx) is seems too easy for me, to be true.

I need to express the sinh-1(x) as a power series in terms of powers of x. I have written the expression as x=sinhy and expanded the sinhy using the exponential series to give x = y+(1/3)y^3+(1/5)y^5+... I guess I need to expand the y=sinh-1(x) and compare or equate the coefficients. If this...

i can perfom the same inversion in two ways: 1. using N data and k model parameters 2. using 3*N data and k+3 model parameters where N>>k. how can I choose the best result between the two? thanks

Find the inverse transform of \frac{\sin{a\omega}}{\omega} I know the step function has a transform of this form, so I as able to find the inverse transform by assuming it was some step function and then looked for the right constants. However, I would like to also know how to do...

Can someone with a graphing calculator give me the inverse of this matrix? \begin{array}{ccc} 0&1&2\\ 1&0&3\\ 4&-3&8 \end{array}

hi, does anyone know the character table for the inversion group?

Hello, i have developed a formula for inverting a dirichlet series ,and i apply to solve Phi(n),Mu(n) and d(n) arithmetical function,also i give a formula to obtain the Pi(n) function by means of a triple integral, the paper is in .doc format but if someone want to see it in .pdf can go to...

given the Dirichlet series Sum(0,infinite)a(n)n-^s=f(s) would be an analityc formula to invert the Dirichlet series to obtain a(n)?..i have searched it at google but found no results.

i have got a TAT but when it becomes TAC, this is called an insertion, I think its the same as deletion, or inversion, so I am stuck at how to make a difference between them ? Can you help me ?thanx

insertion, deletion, inversion ? Help me with examples please, thanks

OK, I realize this may be more geophysics then "geology", but I beg for leniency. I have recently been exchanging e-mails with Dr. Daniel Lathrop of the University of Maryland. He is currently involved in a project attempting to model the Earth's magnetic field and, in particular, polar...

Anybody know of a link to a page that describes an algorithm for matrix inversion. My old linear algebra book describes a 'by hand' method, but it's unsuitable for automating.
