Abstract Algebra

Have you ever wondered what would happen if you redefined some of the basic rules of algebra so that concepts you took for granted, like AB = BA, no longer apply? Abstract algebra does just that through the study of the properties that define algebraic structures. Post all questions about fields, rings, group theory, vector spaces, and the axioms that define them into this category.

What is the value of an USA 1876 .50 coin?

Depending on condition:

$20 to $90 if from the Philadelphia or San Francisco mints
$25 to $200 if from Carson City.

Who discovered set theory?

Discoverer of a particular mathematical concept is hard to say as a certain concept is accepted or emerged after many researches.But for set theory as far as we know there is only a single discoverer named Georg Cantor.

What is the value of a 1972 repvbblica italiana L100 coin?

It has no monetary value since Italy adopted the Euro. It will have little or no numismatic value unless it is in uncirculated condition. The TV shopping channels are hanging the demonetized lira coins from necklaces and charm bracelets at high prices, though.

What are eigenvalues and eigenvectors?

An eigenvector is a vector which, when transformed by a given matrix, is merely multiplied by a scalar constant; its direction isn't changed. An eigenvalue, in this context, is the factor by which the eigenvector is multiplied when transformed.

What is the value of 102 Atari 2600 Games?

well depending on condition and how much u paid for them, they could be worth 125-150$ depending on the name of the game

What is the collision-ring theory?

the collision ring theory is a theory about how the moon formed. It says that a planet sized objoct hit earth while it was still young and exploded on inpact. Then the debris formed the moon as the magma cooled.

Do you have to algebra to be an EMT?

If you're asking if it's extremely important to be skilled in algebra, no. However, I doubt any place would accept someone who failed or didn't take any algebra classes.

Value on a 5 shooter 38revolver?

From wall hanger to multiple thousands of USD. Need a detailed description to narrow it down.

How do you generate a parity check matrix?

In order to generate the parity check matrix you must first have the generator matrix and the codeword to check and see if it is correct.

1. Place your generator in row reduction form

2. Get the basis vectors

3. Put the vectors together to get the parity check matrix

4. Check it b multiplying the codewords by the parity = 0

For an example: 2*4 Generator Matrix

[1 0 1 1

0 1 1 0]

Rank = 2...therefore the number of columns is 2...Rank + X = # of columns of the Generator matrix

v1+v3+v4 = 0

v2+v3 = 0

v1 = -r1-r2

v2 = -r1

v3 = r1

v4 = r2

Parity = [-1 -1

-1 0

1 0

0 1]

What is scalar field?

In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number, or a physical quantity.

Are the magnetic field vector- or scalar fields?

Both, E=Es + Ev = cB therefore, B= Es/c + Ev/c = Bs + Bv.

The electric and magnetic fields are quaternion fields consisting of a scalar field and a vector field.

Contemporary Physics has not realized this yet. Correct Relativity Theory is a manifestation of quaternion fields, consisting of a scalar field and three vector fields. This shows up in the Energy Momentum four vector, E= Es +cmV.

Actually the Lorentz Force is both scalar and vector: F=qvB = - qv.B + qvxB

it makes no sense consider only qvxB and to ignore qv.B.

What is Freight rate per mile?

freight rate per mile usually mean a full truck load or full pup load. this is the amount of money the trucking company will charge you for the load based on mileage from the pick up location to the delivery location.

You can get current national per mile rates for free at www.fairtran.com/rates.aspx

What is the value of a Goldwing GL1500?

The Gl1500's range in price from a older model high miles ($5500-$8500) newer bikes will go from ($8500-$14,000) New 1500's and 1800's run from $19,500-$24,000.

What is the value of old 78 records?

This is an easy question. Simply put - 78's can be valued from free to thousands per disc. Of course the value more accurately depends on demand, condition, artist, and rarity. Maybe a few other things also. I have nearly 30 thousand discs and some day would like to have them appraised. A time consuming job to say the least. I have been inventorying and organizing them for years. Finally as to value, you must factor in the love of them as well. Good luck with this. Some might say priceless. Hope this helps. I'm still trying to figure it out for myself.

Highpoint 380 model number 380 what is the value?

Suggested retail is $120, so actual retail would be around $100. Used, $50 to $75.

What is intracellular matrix?

All the gunk free floating inside of a cell.

What is the value of a browning bl22 long 8?

Check the auction sites. To many variables that you don't address, like overall condition, accessories, box, manual, number of rounds fired, etc..

What is the value of a 1963 dollar?

Assuming you're referring to a 1963 US $1 bill, these are common among collectors. As of 10/2012 they retail for less than $1.50 in average condition. A nice uncirculated one might bring $2 to $2.50. A dealer will only pay close to face value because they probably have all they need.
