Math Essay Example: Magic Polygons

The historical backdrop of Magic Polygons goes back a large number of years. As per a 2010 New York Times article by Pam Belluck an Egyptian archive entitled the Rhind Mathematical Papyrus goes back to 1650 B.C., which would make it more than 3600 years of age. It is truth be told the graphical comparable to a popular limerick called the St. Ives Conundrum. As it goes, "As I was going to St. Ives I met a man with seven spouses, every wife had seven sacks, each sack had seven felines, and each feline had seven units... What number of were going to St. Ives" (Alchin, 2015). I recollect when my green bean variable based math educator started the second semester, and we strolled into the class with this perplex on the board. We were finding out about examples, yet I didn't interface that at the time.

2.0 Magic squares

It is anything but difficult to influence you to comprehend what the magic squares are by demonstrating it. It is referred to well as a perplex for kids. It is anything but difficult to how it functions, and there is an intrigue how it is made. There is a straightforward run to make it. The aggregate of one of any lines is constantly same to another entirety. For this situation, there are eight of correspondence. 8+1+6 =6+7+2 =4+9+2 =8+3+4 =3+5+7 =1+5+9 =8+5+2 =6+5+4

There are additionally numerous sorts in magic squares. This is basic, yet in addition baffling. There is a legend that the magic square was composed on the shell of turtle in 3000b.c. It demonstrates that people knew it from the far past. It was utilized as charms by seers in medieval Europe in view of secret. It was found in India and Egypt for quite a while back, as well.

Quick forward numerous hundreds of years to Leonard Euler principally certify to making what we know today as Sudoku. Conceived in 1707 in Switzerland Euler took after the numerical work of Sir Isaac Newton, Descartes and his dad an arithmetic instructor. Their lessons helped him to create number hypothesis and chart hypothesis which is basic to the development and fundamental ideas found in Sudoku. We will examine these subjects top to bottom later in our talk. In his side interests something close to 1783, Euler built up the nuts and bolts for Latin Squares, which is a n by n square containing the numbers 1 through n, each of which just shows up once per line and section in the square. An example of a simple Latin square is below:

A B C

B C A

C A B

2.1 magic polygons characteristics

Each individual box is called a cell. So, a magic square is an arrangement having the following properties:

There are equal numbers of cells if counted horizontally or vertically so that the whole arrangement looks like a square.

The cells are filled with consecutive natural numbers starting from 1.

The sum of numbers in each row, each column and also in the main diagonals is same

The total number of cells in a row (or column) of a magic square is known as its order. Thus the above magic square is of order 3. Obviously, the smallest magic square is of order 1 which consists of just one single cell.

So, magic squares of all orders are not possible. But if a magic square of certain order, say, n, can be constructed then the magic sum can be calculated by the formula

N (n2 1). One can check that for a magic square of order 3, this formula gives the value 15 which is the magic sum. Similarly, the magic sums for the magic squares of orders 4 and 5 are respectively, 34 and 65.

Magic square of a particular order is not unique. There can be many magic squares of the same order. Since the numbers inserted in the square of a particular order must be same and also the magic sum should remain same, to generate new magic square, the numbers change their places. Consider the following magic square of order 3 and compare it with the one given earlier.

357

816

We can still have more magic squares of order 3. In fact, all rotations and reflections (in a mirror perpendicular to the paper) give different magic squares. For each square, there are four rotations and each rotation gives two mirror images. Thus there are at least 8 magic squares of each order. However, magic squares of order higher than 3 could have many more combinations, as we shall discuss later.

Magic square of order 4. A 4-order magic square is the following:

163213

510118

96712

3.0 Magic squares application in Sudoku

Magic squares initially excused on the quantity of blends and for basic squares this size, there are around 50 mixes. As you can envision, the more squares, the more conceivable outcomes. From the Latin and magic squares of hundreds of years prior comes the upgraded idea for magic squares which showed up in two French papers between 1890-1920 which expelled a portion of the numbers or letters in the square leaving the solver to work out what was absent. All through this time, most Americans were uninformed of these riddles so when Howard Garnes and Dell initially presented the baffle in 1979 individuals were fascinated. This new interpretation of magic squares included nine by nine squares; three lines by three segments which each contained a Latin square blend.

Like the rethought French magic squares, Numbers Place, the first name as found in the once exceptionally prominent Dell Puzzle Magazine in 1979. With Numbers Place each of the squares contained missing components meaning the solver needed to fill in the missing ranges, however this new confound accompanied similar necessities related with the before variants and another curve. Rather than rising to a whole toward the finish of each line-no square or section could rehash a similar number twice. An example of a standard Sudoku puzzle with the original puzzle in black lettering and the solved puzzles showing answers in red is below:

4.0 Pseudo magic squares

The theory of pseudo-magic squares and polygons magic squares is crucial in learning shapes in math. Also, we have demonstrated that the arrangement of nonspecific (pseudo) magic squares has a gathering (ring) structure. Furthermore, a few properties of PMS and GMS and in addition developments of new PMS's from old ones have additionally been exhibited. From the substance showed in this paper, it can be watched that there exist much work as for our new way to deal with be finished. Other intriguing plausibility is the presentation of a topological structure in GMS's

Pseudo magic square (PMS). We demonstrate that a PMS have a characteristic gathering structure. Furthermore, we sum up this new idea to acquire a nonspecific magic square (GMS), which is gotten from a self-assertive gathering (ring). The structure of a gathering (ring) initiates a gathering (ring) structure in the arrangement of GMS's. In view of these actualities, one can see that our approach is very unique of the ones accessible in writing (La Guardia 39)

4.1 Application of GMS

Additionally, we generalize this new concept by introducing a group (ring) structure over it. This new approach can provide useful tools in order to find new non-isomorphic pseudo magic squares (Conway 45)

5.0 criteria of Magic squares application on other shapes.

A Franklin magic square is a semi-magic square with each of the four primary bowed line wholes equivalent to the magic consistent. Every one of the lines and sections whole to the number 260 [260 = 22x5x13], yet that isn't all. Half lines and half segments whole to 130. The four sections in each 2x2 sub square entirety to 130. Be that as it may, there is considerably more! Rather than requiring corner to corner wholes to be steady (as in a completely magic square), Franklin utilized "bowed lines, for example, those featured underneath. Franklin wanted to gauge 'magic' utilizing an alternate sort of askew from his antecedent Frenicle utilizing a shape which he called a "bent row."

5.1 magic squares construction

With many unsolved problem to determine the number of magic squares of an arbitrary order, be that as it may, the quantity of unmistakable magic squares (barring those acquired by revolution and reflection) of request n=1, 2, ... are 1, 0, 1, 880, 275305224, ... (OEIS A006052; Madachy 1979, p. 87). The 880 squares of request four were counted by Frenicle de Bessy in 1693, and are delineated in Berlekamp et al. (1982, pp. 778-783). The quantity of 55 magic squares was processed by R. Schroeppel in 1973. The quantity of 66 squares isn't known, yet Pinn and Wieczerkowski (1998) evaluated it to be (1.7745+/ - 0.0016)10^(19) utilizing Monte Carlo reproduction and strategies from factual mechanics. Strategies for specifying magic squares are examined by Berlekamp et al. (1982) and on the MathPages site.

A square that neglects to be magic simply because either of the principle corner to corner wholes don't equivalent the magic consistent is known as a semimagic square. In the event that all diagonals (counting those acquired by wrapping around) of a magic square whole to the magic consistent, the square is said to be a panmagic square (additionally called a malicious square or pandiagonal square). On the off chance that supplanting each number n_i by its square n_i^2 produces another magic square, the square is said to be a bimagic square (or doubly magic square). In the event that a square is magic for n_i, n_i^2, and n_i^3, it is known as a trimagic square (or trebly magic square). On the off chance that all sets of numbers symmetrically inverse the inside total to n^2+1, the square is said to be an affiliated magic square (Lin 30)

Squares that are magic under duplication rather than expansion can be developed and are known as augmentation magic squares. What's more, squares that are magic under both expansion and increase can be developed and are known as expansion duplication magic squares. What's more, as appeared beneath they can be utilized as a part of age of various shapes

5.2 derivative

The magic constant of a normal magic square depends only on n and has the value M = (n3 + n)/2. Here is the verification. Given a typical magic square, assume M is the number that each line, segment and corner to corner must mean. At that point since there are n pushes the whole of the considerable number of numbers in the magic square should be . However, the numbers being included are 1, 2, 3, ... n2, thus 1 + 2 + 3 + ... + n2 = . In summation documentation, . Utilizing the equation for this entirety, we have , and after that settling for M gives . In this manner, a Lo Shu's typical magic square should have its lines, segments and diagonals adding to , an Albrecht Durer's to M = 34, a Benjamin Franklin's to M = 260, et cetera

6.0 Conclusion

In this paper, a few sorts of magic geometrical shapes are presented briey. At that point, the most critical sorts of magic squares and their highlights are portrayed. In addition, development Methods of regular magic squares together with their essential properties are communicated. At long last, the absolute most impressive unsolved issues are surveyed, and intriguing physical utilizations of magic squares are broke down. Physical use of magic squares is as yet another point that should be investigated more.
