Mesir have been found? esteeming by 3,16. They understand from area of circle square is same 8 / 9 times diameter.
People since measurement radian introduced have Egypt 2450 SM with triangle interralate. In throw rhind and moskow can find geometry duty. Which, area of circle which is same sawed eight to the nine time diameter and then real correct cylinder volume of is same elementary time height area. Hence, we earn separate is same area of circle eight to the nine times diameter in square bracket. Our know that is same diameter twice radius, and then can find from that is same circle eight to the nine times twice radius in which is same square sixty four to the eighty once four times radius which is same square two hundreds fivety six to the eighty once radius which is same square three dot one six times square radius. Hence, people in Egypt have found phy is three dot one six. And then analytic wisthel phy which is same phy three dot one four.

HOW TO DETERMINE ABC FORMULA
Square equations of universal is “a” times x square plus “b” times x plus “c” equals zero. And then, if we want to difference square equation of universal.
With all over coeffisien with “a” and then we will piocure x square plus “b’ over “a” times x plus “c’ over “a” equals zero. And then we are plus to second internade with “b” square over open bracket four times “a” square close bracket. So be can equation is x square plus “b” over “a” square plus “b” square over open bracket four times “a” square close bracket equals “b” square over open bracket four times “a” square close bracket. We will a group to x plus open bracket two “a” close bracket equals b square over four “a” square minus c over a equals b square minus four times “a” times “c’ in bracket all over four times a square in bracket. So, be can x plus “b” over open bracket two times “a” close bracket equals plus minus “b” square minus four times “a” times in bracket all over open bracket four times “a” square in bracket square root. So, we will x equals minus b plus minus open bracket “b” square minus four times “a” times “c” in bracket square root close bracket all over open bracket two times “a”. So, we can abc formula is x equals minus “b” plus minus open bracket “b” square minus four times “a” times “c” in bracket square root close bracket all over open bracket two times a close bracket.

How to proof square root of 2 is irrational number
Greek ancient find square root of 2 wasn’t rational although square root of 2 was the length of hypotenuse with upright side triangles was 1. The number cannot write as result from integer number. So the square root of 2 is irrational.
The proof:
Rational number is the number which can be stated in ratio a over b, a and b the integer number which do not have factor partner and b unequal 0
If square root of 2 is rational number, then :
Square root of 2 equals a over b times r
¬2 equals a square over b square
¬a square equals 2 times b square (2b square is the integer number, integer times 2 is even number )
¬a square equals even
¬a equals even………(1)
¬a equals 2n (n is integer number)
¬a square equals 4n square
¬2 times b square equals 4n square
¬b square equals 2n square
¬b square is even………(2)
¬b equals even
From equation 1 and 2 we know that a and b are even.
a and b are even, so they have factor partner that is 2. The entire step is right, that is the opposite with the definition of the rational number. It means the proof is wrong, so square root of 2 is irrational.

Exercise!
1. The characteristics of logarithm
first characteristic,
Remember of Exponent function:
• a to the power of m times a to the power of n equals a to the power of m plus n
• a to the power of m over a to the power of n equals a to the power of m minus n
if b logarithm to the base a equals n, so b equals a to the power of n
if a logarithm to the base g equals x, so a equals g to the power of x
if b logarithm to the base g equals y, so b equals g to the power of y
what is the answer of a times b in bracket logarithm to the base g? if a logarithm to the base g equals x, so a equals g to the power of x and b logarithm to the base g equals y, so b equals g to the power of y, we can conclude a times b equals g to the power of x in bracket times g to the power of x in bracket, then we get a times b equals g to the power of x plus y. we can get a times b in bracket logarithm to the base g equals g to the power of x plus y in bracket logarithm to the base g, equals x plus y in bracket times g logarithm to the base g ( we know that g logarithm to the base g equals one), so it equals a plus b. we can conclude that a times b in bracket logarithm to the base g equals a plus b.
then we look:
• a over b equals g to the power of x in bracket over g to the power of y
• a over b equals g to the power of x minus y in bracket
• a over b logarithm to the base g equals g to the power of x minus y in bracket logarithm to the base g equals x minus y in bracket times g logarithm to the power of g, equals x minus y.
so we can conclude a over b logarithm to the base g equals a logarithm to the base g minus b logarithm to the power of g.
second characteristic,
• if a logarithm to the power of g equals x so a equals g to the power of x
• if b logarithm to the power of g equals y so b equals g to the power of y
first characteristic,

• a to the power of m times a to the power of n equals a to the power of m plus n
• a to the power of m over a to the power of n equals a to the power of m minus n
if b logarithm to the base a equals n, so b equals a to the power of n
if a logarithm to the base g equals x, so a equals g to the power of x
if b logarithm to the base g equals y, so b equals g to the power of y
what is the answer of a times b in bracket logarithm to the base g? if a logarithm to the base g equals x, so a equals g to the power of x and b logarithm to the base g equals y, so b equals g to the power of y, we can conclude a times b equals g to the power of x in bracket times g to the power of x in bracket, then we get a times b equals g to the power of x plus y. we can get a times b in bracket logarithm to the base g equals g to the power of x plus y in bracket logarithm to the base g, equals x plus y in bracket times g logarithm to the base g ( we know that g logarithm to the base g equals one), so it equals a plus b. we can conclude that a times b in bracket logarithm to the base g equals a plus b.
then we look:
• a over b equals g to the power of x in bracket over g to the power of y
• a over b equals g to the power of x minus y in bracket
• a over b logarithm to the base g equals g to the power of x minus y in bracket logarithm to the base g equals x minus y in bracket times g logarithm to the power of g, equals x minus y.
so we can conclude a over b logarithm to the base g equals a logarithm to the base g minus b logarithm to the power of g.
second characteristic,
• if a logarithm to the power of g equals x so a equals g to the power of x
• if b logarithm to the power of g equals y so b equals g to the power of y

I wish can converse and comprehend skilled also in have Ianguage to English, because conscious me that Ianguage English of vital importance and always equiping of various science. Ianguage Inggris it is true have mushroom, may even exist people spell out members except that Ianguage can English mean he/she is the inclusive of one who do not follow the globalization current which modern progressively this sophisticated and.
According to myself, I feel very difficult to learn the Ianguage English, but I thirst for the Ianguage can English. What I wish to do for the English of for Mathematics is Ianguage me can common English also in English for Mathematics.

IT IS A MUST THAT A HAVE A COMPETENCE IN ENGLISH FOR MATH EDUCATION
Competent is skilled needed by a somebody posed at by its ability to consistently give the high or adequate performance storey level in a specific work function. That competent which must be owned by alll student in learning in English for math and also other science. Competent represent the authorized capital to prepare the self in accepting study. If student do not own the competent hence he/she will not ready to accept the Iesson and tend to offish at the Iesson. Therefore, student will be weak in the subject.
Become, according to that competent me of vital importance and have to be owned by each every student of to be they can draw up and holding responsible with a Iesson. Ought to there is strive the assistive other party or educator of student to awaken the existing competence is student self of to be its his important awareness of student is competence for them.
