Applications of Algebra

admin — Sat, 08 May 2010 02:43:08 +0000

Mathematics has many branches and algebra is one of the most emphasized branches which studies structure, relation and quantity. Algebra operates with numbers, symbols, elements and variables. Basic algebra is an introduction to constructs in algebra like solving radical systems of equations, understanding polynomials along with factoring binomials, trinomials and polynomials as well as the determination of their roots.
Linear inequalities are the simplest to solve. Simultaneous equations with two or three variables is an extension of linear equations . As we advance further in the sequence to quadratic, bi-quadratic and cubic equations, they are more complex in nature and harder to solve.

The Roots of Algebra

Elementary algebra constitutes the intermediate or college algebra. In addition to mathematical expressions, it also contains of all kinds of equations like linear , quadratic and cubic. All geometric figures such as circle, hyperbola, and parabola can be presented as equations.
The equations can be resolved for different conditions by creating a graph. Lines are the product of graphing simple linear equations. It is quite simple to find a solution to the systems of equations when represented graphically. Two or more equations with the same number of variables are normally identified as a system of equations. They can be both linear and non-linear. Systems of equations with inequalities (example; x>y) when graphed gives an region on the graph which matches the inequality condition.

Matrices are one of the most key areas of linear algebra which aids solving complex problems like the ones existing in electrical networks. A matrix is a rectangular range of numbers presented in rows and columns. A matrix comprise of many numbers and they are called entries. Different operations like addition, multiplication and decomposition can be performed on matrices thereby offering theoretically and practically useful mathematical answers.

The Christmas Star: Was it a Planetary Conjunction?

admin — Wed, 09 Dec 2009 20:02:25 +0000

The Christmas Star, some say, was a planetary conjunction. But possibly no previous planetary grouping can be equivalent to that of the two most halcyon planets Venus and Jupiter for the explanation that we seek. And if we involve the only famed explanation of the Star literally, as dedicated in St. Matthew, then what we genuinely require is the appearance of not barely one, but two “stars.” The first appearance would have been witnessed well in advance of the Magis arrival in Bethlehem, and the other at the end of their long journey.

In Hellenistic astrology, Jupiter was the male monarch planet and Regulus (in the constellation Leo) was the Rex star. As they traveled from Jerusalem to Bethlehem, the star “went before” the magi and then “stood over” the position where Jesus lived. In astrological versions, these phrases are supposed to refer to backward motion and to stationing, i.e., Jupiter seemed to reverse track for a time, then discontinued, and ultimately resumed its normal progression. In about 2 or 3 BC, there was a series of seven alignments, including three between Jupiter and Regulus and a strikingly conjunction between Jupiter and Venus close Regulus on June 17, 2 BC. “The fusion of two planets would have been a exceptional and awe-inspiring event” – according to many astronomers.

Others have suggested a connection between a double occultation of Jupiter by the moon in 6 BC in Aries and the Star of Bethlehem, especially the second occultation on April 17. This event was quite nearby to the sun and would have been challenging to find, even with a small telescope, which had not yet been manufactured. Occultations of planets by the moon are quite usual, but an astrologer to Roman Emperor Constantine wrote that an eclipse of Jupiter in Aries was a announcement of the birth of a divine king.

“When the majestic star of Zeus, the planet Jupiter, was in the east this was the most robust time to confer kingships. Moreover, the Sun was in Aries where it is glorified. And the Moon was in very close conjunction with Jupiter in Aries.”

Hard Science: Algebra

admin — Tue, 08 Sep 2009 23:18:13 +0000

After an exclusive search over the reasons behind the maximum school dropouts, a consistency was found in the answers of the majority of the participants pointing towards Algebra. The thoroughness of knowledge of the tutor is not merely enough for students to understand the algebraic concepts, nor it is adequate to rekindle interest about the field of study. It’s the method; the subject matter is delivered to its recipient which leads a lot for developing interest in the contents.

What is it?

A shortened introduction of Algebra would be a branch of mathematics which replaces letters for numbers; algebraic equation is a scale. The fundamental concepts of algebra includes real numbers, complex numbers, matrices and vectors.

The Different Domains

Algebra in general addresses a lot of areas. for example; Multiplying exponents, dividing exponents, Solving quadratic equations , Finding Greatest common factor or GCM, Multiplying, Adding, Subtracting fractions and many more.

If these areas have scared you, then I must give you some definitions which will really ease the gravity and give you the real essence of algebra.

Exponents are just shorthand for referring multiplication of identical factors. Fractions are equally interesting and actually are used when representing numbers that describe the parts of a whole. Many such similar areas in algebra may sound scary at the beginning, but once you comprehend the simple concept behind it, you will be enthralled by its purpose. To state a few more – Mixed numbers, Quadratic formula, Graphing linear inequalities, solving compound in equalities , Factoring binomials, and Factoring polynomials; are all algebraic expressions.

Although you may find it confusing to understand mixed numbers, but it will really interest you to note that they are none other than a type of fractions. Similarly, graphing linear equalities may be self explanatory and there are many other similar algebraic expressions that may sound complicated but are extremely interesting to work with.

How to Find a Private Instructor

If you want to quench your thirst for algebraic knowledge further and you do not have any tutors there is nothing to worry about. Because There are online lessons too. These tutorials emphasize the practicalities instead of technicalities, showing dependable techniques. The algebra solver software systems can guide you stepwise in solving your maths problems and it can also provide explanations of all steps.

What Should We Do with Algebra?

admin — Fri, 31 Jul 2009 14:43:12 +0000

Algebra is the one which is used for getting our daily tasks accomplished. The mankind constantly continues counting, measuring, dividing, and multiplying.

The History

Invented in the first millennium BC, algebra was first invented in the middle-east. The ancient brains used algebra for solving daily problems while the Asian or rather Chinese counterpart employed geometry for the same function

What is the Nature of Algebra?

Although you may see algebra as solving formulas , simplifying rational expressions, and converting fractions to decimals, algebra has a much wider body of knowledge and applicability. Since this aspect has been understood, the education system pushes us to study algebra from the inception of our pupil life.

Algebra I

The students are given an introduction in this study course to numbers, solving linear equations, graphing systems of linear equations, graphing linear inequalities, laws of exponents, resolving quadratic equations , and factoring polynomials. This course of study places the groundwork for the rest of the higher algebra waiting to be explored in the next two stages.
If a pupil is keen on studying algebra down to its roots, then this is the most central study course.

Algebra II

Once the pupils are competent with Algebra I constructs, Algebra II can be taken up for broadening the spectrum of this exceptional section of mathematics. There are two views of Algebra II; stressing more on the topics learned in Algebra I and foundation to new concepts. When it comes to the new introductions, adding and subtracting matrices, quadratic functions, solving exponential equations, probability and statistics are notable.
In this plane of study, pupils are required to stress more on the fundamental constructs.

College Algebra

This is one of the most significant degrees of learning Algebra with virtually no new topic brought in. I assume it is quite funny, but this is the nature of maths. Do you know why maths is called the queen of all scientific disciplines ? That’s because of the unforeseeable nature of maths!

How to get aid on Algebra?

There are many methods and tools accessible for getting assistance for Algebra subject areas. The first and the foremost key source is an Algebra instructor from whom you can get help and aid.
In addition to books, one should never underestimate the use of Algebra software program that is particularly designed to solve algebraic problems with informative steps. This software system really adds insight in to Algebraic operations of solving equations, by allowing students to simply watch and learn through examples.

Oncologists Wield Breakthrough Alternatives in Fight against Mesothelioma, though Prognosis Looks Grim

admin — Tue, 07 Jul 2009 08:27:05 +0000

Oncologists choose what course of treatment to go with with a patient. There are numerous options. There are no universal treatment option for peritoneal mesothelioma cancer patients. This is due to the cancers high mortality rate, rareness, low treatment success rate, and small number of studies to provide meaningful statistics.

Mesothelioma patients have historically had a bleak outlook, but doctors have recently made progress. Customary treatments for cancer are surgery (removing the tumor and the tissue that surrounds it), radiation (killing the cancerous cells with radiation), and chemotherapy (poisoning the cancerous cells.) All three methods have problems. Traditional radiation therapy has not worked well with mesothelioma patients. Researches, concerned about damage to healthy tissue, are looking for ways to aim radiation directly at tumors.

The mesothelial tissue around the tumor is removed by surgery. It is a grueling surgery with unknown benefits to patients. Common chemotherapy drugs that work on other types of cancer usually do not work on mesothelioma, and combinations of chemotherapy agents have been tried, but without much success. Like radiation, researchers are focusing their work on controlling the physical location of the treatment with an emphasis on the pleural cavity.

The death rate for mesothelioma is so high that many of even the most sophisticated techniques in cancer treatment are tried out on patients. These techniques include a biologic therapy called the agent interleukin 2 and anti-angiogenesis drugs like thalidomide. The new drug pemetrexed (brand name Alimta) has shown good results in extending life with mesotheliomas..

Considered by oncologists is where the tumor is located, what stage the mesothelioma is in, and the age and health of the patient. Theres also photodynamic therapy and gene therapy ” two far-out new ways of attacking cancer. Patients afflicted with mesothelioma are benefitting in these clinical trials.

Algebra, Is it Really that Essential?

admin — Sun, 28 Jun 2009 18:53:30 +0000

We can say that Algebra is the core of math . An in depth knowledge of algebra and its basics is required before you could work on more complex mathematical problems . Deriving the result for the product of 223 and 112 is quite easy if you use a computer. However, in a case where you need to work around the exponential of 223 and logarithm of 112, you will surely need an algebraic software application. Graphing a circle will be easy for this given formula X² + Y² = 4 but when it comes for an inequality like (X-2)² + (Y-4)² > 20 then it will be quite harder to plot the graph. In this situation algebra software can help you a great deal because once you enter the inequality in the program, the graph will get plotted automatically within no time. These kinds of packages can very easily resolve any kind of algebraic, arithmetic and radical expressions of any kind of complexity.

Finding Domain and Range of a Function

Now it is very easy to derive the domain and range of functions like Y = X², you can just tell that X and Y can take any real number from the X-Y plane but have you ever thought of defining the domain and range of log(tan 2x + sin 3x) = cosine^(-4)(2x). But now you can solve such critical and complex problems with an algebra calculator without breaking sweat and you will also be getting all the steps as well

Coordinate Geometry

Now you can easily find the vertex and directrix and whether parabola opens up or down by just feeding the equation into algebra software system. In addition, subtraction and multiplication of polynomials, you are more likely to become drained because they require a lot of terms to be manipulated. But algebra calculator will do this job in much less time and with 100% accuracy. Similarly, algebra calculators can save the trouble for you in calculating matrices of 33 or 44 order or its inverse matrices.

So, with the introduction of algebra software packages, the times where you dreaded the sight of indices, fractions or fractional equations , comes to an end. If you could not stand geometry, you may even start liking it now thanks to the computerized algebra calculators that will automatically simplify everything you ever need.
