In this paper i will discuss the way expression has changed from the way it was in prehistoric times to the present time. The three items that have evolved are non verbal communication, speech, and the writting format.

First of all non verbal comminunication the has evolved by simple movements to sign language. what is non verbal communication? The sending and receiving of messages thru movements of the body, postures and expressions of the face. Example the shking of a raaised fist to show a sign af anger, is know expressed in sign laanguage as movement of hands with finger slightly bent from your stomach towards your grimaced face. ”www.ehow.com/video_4403498_sign-feelings-sign-language.htm”

Secondly speech has also evolved by putting basic phonemes and syllables together and forming words and phrases. people have become lazy by not pronunciationg syllables correctly and trying to come up with shortcuts to get messages across. Slang words have been made to make a word such as fat to mean many meanings such as phat like pretty hot and tempting.

Finally writting has evolved by making rules such as the rules found on page 308 in Esl Doxography 101 (2006), Dr. Clark von Heller. For example, rule #8 never use “there” except as a position or place. Youths of today have forgoten the rules of writing due to the new technology avalable such as texting and emailing.

in conclusion the three items that have evolved are non verbal communiton, speeech, and the writing format. these are the things that have made changes of expression possible. i do not believe some of these things are good because people have forgoten the rules that made speech beautiful.

...term of the sequence. When writing the general expression for an arithmetic sequence, you will not actually find a value for this. It will be part of your formula much in the same way x’s and y’s are part of algebraic equations.
a1 is the first term in the sequence. To find the explicit formula, you will need to be given (or use computations to find out) the first term and use that value in the formula.
n is treated like the variable in a sequence. For example, when writing the general explicit formula, n is the variable and does not take on a value. But if you want to find the 12th term, then n does take on a value and it would be 12.
d is the common difference for the arithmetic sequence. You will either be given this value or be given enough information to compute it. You must substitute a value for d into the formula.
You must also simplify your formula as much as possible.
Let's Practice:
i.Write the explicit formula for the sequence that we were working with earlier.
20, 24, 28, 32, 36, . . .
The first term in the sequence is 20 and the common difference is 4. This is enough information to write the explicit formula.
Now we have to simplify this expression to obtain our final answer.
So the explicit (or closed) formula for the arithmetic sequence is .
Notice that an the and n terms did not take on numeric values. They are a part of the formula, again like x’s and y’s in algebraic...

Algebraic expression

History:
Ancient civilizations wrote out algebraic expressions using only occasional abbreviations, but by medieval times Islamic mathematicians were able to talk about arbitrarily high powers of the unknown x, and work out the basic algebra of polynomials (without yet using modern symbolism). This included the ability to multiply, divide, and find square roots of polynomials as well as knowledge of the binomial theorem. The Persian mathematician, astronomer, and poet Omar Khayyam showed how to express roots of cubic equations by line segments obtained by intersecting conic sections, but he could not find a formula for the roots. A Latin translation of Al-Khwarizmi's Algebra appeared in the 12th century. In the early 13th century, the great Italian mathematician Leonardo Fibonacci achieved a close approximation to the solution of the cubic equation x3+ 2x2 + cx = d. Because Fibonacci had travelled in Islamic lands, he probably used an Arabic method of successive approximations.

...Freedom of Expression
There are some issues and problems that are very hard to solve. Freedom of expression is one of them. Its hardship springs from the ambiguity of the term freedom itself. Philosophers always ponder on the question as to whether freedom has its own bounds, or it referres to the absence of any kind of restrictions. There are some people asserting that people can express themselves however they want, and all kinds ofexpression should be tolerated. However, In my opinion the way people express themselves determines the decision as to whether this expression is allowed or not.
The radical idea that people are entitled to express themselves however they want sounds romantic and inconsistent. Expression is a broad term and it does not only include arts, but also insult and blasphemy. Therefore if we let every idea be expressed, then we also close our eyes to insulting. According to the Universal Declaration of Human Rights (UDHR) people have dignity. So does not disregarding, cursing and insulting someone lead to the violation of human rights? I think it breaches the idea of dignity and equality.
However, we should not draw such a conclusion that all we can do is to stay calm. Without insult we can express our ideas and thoughts in an appropriate way. As you realize the term appropriate seems to be subjective and needs to be explained. In this context,...

...TRANSITION EXPRESSION
A Transitional Expression is a Transitional Phrase or a Conjunctive Adverb.
Transitional expressions help your reader to understand how you have organized your material, making it easier for them to move from one point to the next in your writing. Use Transitional expressions to: add ideas, emphasize ideas, illustrate ideas, compare/contrast ideas, show cause and effect, place ideas in time, and summarize ideas.
( Jadi Transitional Expression adalah semacam kata penghubung, antara 2 kalimat / klausa yang dituliskan agar membantu para pembaca untuk lebih mengerti/memahami tulisan tsb.)
Transitional Expression is for identify words or phrases that will indicate for the reader the kind of logical relationships you want to convey.
Two ways in writing transition expression:
1. Use a semi-colon [;] and coma [,] between independent clauses linked with a transitional expression:
eg: I learned all the rules and regulations; however, I never really learned to control the ball.
2. After full stop [.}
eg: Erwin didn’t study. Therefore, he failed the test.
Here are some of the most common transition expression, grouped according to meaning:

Time after, after a short, afterward, at least, at the same time, before that time, before then, immediately, lately, later, meanwhile, now,...

...Finding Faith in Religion
What Constitutes an Expression of Religion?
Name: Megan Campbell
Instructor’s Name: Ms. R. Revington

Course: ENG4U1-03
Date: October 17, 2012
Religion is a worldwide practice and can be different to every individual. I believe that one can practice religion for many different reasons; some just may not involve a strong faith in the religion. To go through the motions of a religion is not the same as having faith in that religion. One can express religion yet not have faith in it, and can just be expressing to appease their family or just feel that it is the thing to do.
There are also many ways to express religion, sometimes depending on what religion is being practiced. An expression of religion can be as simple as praying by your bedside or as expressive as praying 5 times a day in public. There are many things that constitute an expression of religion. One may express religion by going to church on Sundays, praying, singing hymns, and other related activities. Another expression of religion could be reading religious texts. For example, a young Jewish boy reading from the Torah at his Bar Mitzvah, this is a very important expression of religion as he is becoming a man in his culture and has seemingly accepted this religion into his life. All of these expressions can be either legitimate or only to please their family or...
