What I have done and what will I do for English mathematics
That I have done in studied english is full fill vocabulary and more read English article, like to listen western musics and try to write the lyric because usually the lyric of musics is easy listening, write my activity for along day for the example the list of what I will buy, the activity in campus and etc. Also have like to watch the film with English language so usually to hear and see the word in English.
Instead of mathematics I like more read mathematics books which use English language and looking the meaning of it.
That I will do to be more have good quality in English is more have vocabulary,diligent to read English book however have a western friend so easy to understand. More quantity to hear the spoken of or English song.
Because English is the most important language in the world,I always diligent to look, watch,search all everything about hot issue in English languages.
Try to do with the basic of English so practice will make me always study more easy English.
In studying English especially English mathematics we must know some symbolic of mathematics such as the symbol of integers,calculus,and statistics. So,try to read some book of mathematics in English version,so,with this step,I hope more know about everything about symbolize in English of mathematics.
I hope in the future,I can giving a course in English. So,practice make me develop my english

Logarithm Character
Logarithm Character
A to the power of m multiply a to the power of n equal to a to the power of m plus n. a to the power of m divided to the power of n equal to a to the power of m minus n.
Logarithm b with base of number a equal to n meaning to b equal to a to the powr of n.
Example:
- Logarithm a with base of number g equal to x meaning to a equal to g to the power of x.
- Logarithm b with base of number g equal to y meaning to b equal to g to the power of y.
So,for logarithm a multiplied b with base of number g equal to g to the power of x plus y.
- Logarithm a multiplied b with base of number g equal to logarithm g to the power of x plus y with base of number g equal to x plus y in bracket multiply with logarithm g with base of number g equal to x plus y, cause logarithm g with base of number g equal to one.
This is meaning :
Logarithm a multiply b with base of number g equal to logarithm a with base of number g plus logarithm b with base of number g.
- For logarithm a to the power of n with base of number g equal to logarithm a multiply a to n factor based logarithm character equal to logarithm a with base of number g plus logarithm a with base of number g to n factor . so, logarithm a to the power of n with base of number g equal to n multiply logarithm a with bas of number g.
- The other character :
1. Log a solidus b with base of number g equal to log g to the power of g
Meaning x-y in bracket to multiply log g eith base of number g. so, to log a solidus b with base of number g minus log b with base of number g.
How to find a pi
Select a circle with sure diameter,so, circle an between perimeter from each polygon that painted interior.so, that to find separation for pi.
We can account perimeter from polygons in that painted and in round about with side 12,24,48,and 96 and with this to find separation to limited pi.
This is in base worked,and to find that pi between 223/71 and 22/7, or with two decimal number pi equal 3,14.
Method to workout abc formula :
Square equality according to general is a times x square plus bx plus c equal zrro.
- First divide square equality by a.
- Next, increased all articulate by b divide 2a in bracket square.
- The equality to become:
In bracket x plus b divide 2a square equal to b square divide 4a square minus c divide a.
- To become
In bracket x plus b divide 2a square equal to b square minus 4ac divide 4a square.
- Rooted all articulate to become.
X plus in bracket divide 2a equal plus minus in root b square minus 4ac divide 4a.
- X equal in bracket minus b plus minus in root b square minus 4ac divide 2a.
To prove root two is irrasional number
First assuming that root two is irrasional number,it’s meaning root two equal a divide b,with a and b as round number prima,so:
Root two equal a divide b,to become:
A equal b times root two or a square equal two times b square. Cause a square equal two times a round number.so, a square is even,so,a even to.
To suppose a equal two times c so the equality:
Four times c square equal two times b square. Two times c square equal b square.
So,b square even and b even too. This is impossible, cause a and b impossible even cause Is relative primus number. So, assumtion that root two rasional is false
A to the power of m multiply a to the power of n equal to a to the power of m plus n. a to the power of m divided to the power of n equal to a to the power of m minus n.
Logarithm b with base of number a equal to n meaning to b equal to a to the powr of n.
Example:
- Logarithm a with base of number g equal to x meaning to a equal to g to the power of x.
- Logarithm b with base of number g equal to y meaning to b equal to g to the power of y.
So,for logarithm a multiplied b with base of number g equal to g to the power of x plus y.
- Logarithm a multiplied b with base of number g equal to logarithm g to the power of x plus y with base of number g equal to x plus y in bracket multiply with logarithm g with base of number g equal to x plus y, cause logarithm g with base of number g equal to one.
This is meaning :
Logarithm a multiply b with base of number g equal to logarithm a with base of number g plus logarithm b with base of number g.
- For logarithm a to the power of n with base of number g equal to logarithm a multiply a to n factor based logarithm character equal to logarithm a with base of number g plus logarithm a with base of number g to n factor . so, logarithm a to the power of n with base of number g equal to n multiply logarithm a with bas of number g.
- The other character :
1. Log a solidus b with base of number g equal to log g to the power of g
Meaning x-y in bracket to multiply log g eith base of number g. so, to log a solidus b with base of number g minus log b with base of number g.

my observation videos
Do you believe me..???
A child that very to believe to self, he sincere efforts to consider all people,that he can!!!
Don’t confuse a child potency.
What do you know about mathematics?
I know all about mathematics.Mathematics is one of science. Related with mathematics are trigonometry, calculus, exponent, curve, line, etc.
Graph of rational function
- Rational functions denominator can be zero.
- Break (missing point syndrome), because the value is zero, it is not allowed in graph.
- Removable singularity when x = 0 and the value is 0/0
To study of Trigonometry
To suppose that a opposite equal 3
a adjacent equal 4
a hypotanus equal 5
so,for to find sinus, cosines, and tangent we can to use a aimple formula :
SOH : sinus opposite hypotanus ,so to sin value :three over five.
CAH : cos adjacent hypotanus, so to cos value : four over five.
TOA : tangent opposite adjacent ,so to tangent value :three over four.
Logarithm

in essence,the students to feel well mathematics study
so that the students to like mathematics,the teacher an obliged to use aksiomatics mathematics definition to follow in essence school mathematics :
- mathematics is problem solving activity
so,we as a teacher we must to prepare mathematics study area to storm mathematics problem,to help student to look for mathematics solution whit they method,to push the students logica thinking,consist,sistematics,and to develops impotence and skill to storm problem.
- mathematics is creativity to need imagination,intuisi,and discovery.
we must to give a motivation to students so that they can creativity thinking and refleksif,to have new inisiatif,want to know,want to ask,and try to find a solution with they method. so,we an obliged to use a definite method.
- mathematics is instrument communication
whit mathematics we can to communicate whit students about of introduce,to make example and to explain mathematics caracteristic. we can to discuss mathematics problem,raed and write mathematics.

My preparation in participating Mr.Marsigit lesson of english 2
well...
first,i will to introduce my profil...
my name is Ika Mahanani,usually called ika. i live in Klaten specialy in Dimoro Trucuk Klaten. Now i'm university student at Yogyakarta State University.Now,i will explain my experience studying english.since junior school i has studied English and to be continou until now.
My preparation in participating Marsigit lesson of English is now I to learn multiply about of vocabulary and grammar, because according to me it is principal point in learning English language.
After that perhaps repeatly wade of sentence in English language, eventhough while may be only my special preparation . After that I will started learn English language whit pronounced.
I appreciate with English, because I to be aware important English language after shape international language and that very important for me.
for can english language,we must to hear, to talk, to write, to read, to translate/understand mathematics education in English.so we easy to studying english.
