Solving deferential
We will find dy over dx equal four times x square to get the equation y.
• Dy over dx equal four times x square
• Dy equal four times x square dx
• Integral two side, so integral of dy equal integral of four times x square dx
• Integral of dy is y and integral of four times x square dx is four third times x cubeb plus Constanta.
• So y equal four third times x cubeb plus Constanta.

Problem solving:
1. We will find the value of x in equation x minus five equal three.
• X minus five equal three
• Add two side with five, so we get x minus five plus five equal three plus five
• x equal three plus five
• so the value of x in equation x minus five equal three is eight.

2. we will find the value of a in equation seven equal four times a minus one
• seven equal four times a minus one
• add two side with one, so we get seven plus one equal four times a minus one plus one
• eight equal four times a
• multiply two side with a quarter , so we get a quarter times eight equal a quarter times four times a
• a quarter times eight is equal two, and a quarter times four times a is equal a
• so the value of a in equation seven equal four times a minus one is two

3. we will find the value of x in equation two third times x equal eight
• two third times x equal eight
• multiply two side with three second, so we get three second times two third times x equal three second times eight
• three second times two third times x is equal x, and three second times eight is equal twelve
• so the value of x in equation two third times x equal eight is twelve

4. we will find the value of x in equation five minus two times x equal three times x plus one.
• Add two side with negative three times x, so we get five minus five times x equal one
• Add two side with negative five, so we get negative five times equal negative four
• Multiply two side with negative one fifth, negative one fifth times negative five times x is equal x, and negative one fifth times negative four is equal four fifth.
• So the value of x in equation five minus two times x equal three times x plus one is four fifth.

5. We will find the value of m in equation three minus five times open bracket two times m minus five close bracket equal negative two
• three minus five times open bracket two times m minus five close bracket equal negative two
• three minus ten times m plus twenty five equal negative two
• so negative ten times m plus twenty eight equal negative two
• add two side with negative twenty eight, we get negative ten times m equal negative thirty
• divide two side with negative ten , we get negative ten times m over negative ten equal negative thirty over negative ten
• negative ten times m over negative ten is equal m and negative thirty over negative ten is equal three
• so the value of m in equation three minus five times open bracket two times m minus five close bracket equal negative two is three.

6. We will find the value of x in equation a half times x plus a quarter equal one third times x plus five forth
• Multiply two side with twelve, so twelve times a half times x plus a quarter in bracket equal one third times x plus five forth in bracket times twelve
• We get six times x plus three equal four times x plus fifteen
• Add two side with negative four times x, we get two times x plus three equal fifteen
• Add two side with negative three, so two times x equal twelve
• Divide two side with two, so two times x over two is equal x and twelve over two is equal six
• So the value of x in equation a half times x plus a quarter equal one third times x plus five forth

7. We will find the value of x in equation oh point three five times x minus oh point two equal oh point one five times x plus oh point one
• Multiply two side with one hundred, we get thirty five times x minus twenty equal fifteen times x plus ten
• Add two sides with twenty minus fifteen times x, we get twenty times x equal thirty
• Divide two side with twenty, twenty times x over twenty is equal x and thirty over twenty is equal three second
• So the value of x in equation oh point three five times x minus oh point two equal oh point one five times x plus oh point one is equal three second

We will prove that C times logarithm base x of A equal logarithm base x of A to the C in bracket.
• C times logarithm base x of A equal logarithm base x of A to the C in bracket
• We know that if logarithm base x of A equal B, so X to the B equal A,
• So x to the B in bracket to the C equal A to the C
• X to the B times C in bracket equal A to the C, so logarithm base x of A to the C equal B times C. its second equation
• Substitution second equation in first equation, we get C times logarithm base x of A equal logarithm base x of A to the C in bracket. Its shown

We will prove that logarithm base x of A minus logarithm base x of B equal logarithm base x of A over B in bracket
• If logarithm base x of A equal m, so x to the m equal A
• If logarithm base x of B equal n, so x to the n equal B
• If Logarithm base x of A over B in bracket equal p so x to the p equal A over B
• We know that A equal x to the m and B equal x to the n, so x to the p equal x to the m over x to the n
• X to the p equal x to the m minus n in bracket, we get p equal m minus n
• So logarithm base x of A over B equal logarithm base x of A minus logarithm base x of B. its shown.

My reflection in learning English

To know our ability in English lesson, it was done English test. And the result can be used as our reflection. Is our competence in English good or not. So we can know what we must to do for the next step.

The English test result in the last week was very surprised. My result is not good. It means my ability is not good and must be increased. And so is my application.
English lesson is very important in our life to face this global era. Someone who have a little ability in English will have difficulties to face the competition in the future. Someone who is good in English will be easy to win the competition in work world. So, from this time we must optimize our competence in English language.

To increase my ability in English can be done with many ways, some of them are:
• Getting data from blogs
• Access from internet
• Find TOEFL test CD
• Use English in our daily
• Etc

How is the way to make us more competence than our friends?
1. Competence in English
The way to increase our competence in English is like: train our ability in
communication,express idea, understand English language, etc.
2. Competence in Mathematic
What is the really mathematics?
a. Have assumption what is the really mathematics.
b. Understand mathematics concepts.
T here are a lot of concepts in mathematics. Some of them can be definition of a
sentence concept, can define number, line, angle etc.
c. Axioms
Mathematics is analysis.
The truth in Mathematics experiment must based on logic (must be consistent or
there is no contradiction).
That is my reflection in learning english, i hope i can be better in english and mathematics.

The meaning of mathematics

The object of mathematics is abstract object. There are 2 ways to get the abstract object.

1. Abstraction

Abstract and abstraction is different. Example abstract: the price of thing, the value of thing, the material of thing, etc. what happen in mathematics? In mathematics, abstraction means the value of something.

2. Idealization

Nothing is perfect . We always assume that something is perfect, but perfect is God’s. We assume that something is sharp, but truly there is nothing which is sharp perfectly. We assume that line is straight. But truly there isn’t a perfect straight line. Mathematics is an art.

What is the object of mathematics?

The object of mathematics is structure, system, formula, pattern, etc. Mathematics is a science which is formed deductively and contains theorems.

The characteristic of mathematics is logic and consistent.

Based a professor from Melbourne University, the characteristic of mathematics is conjecture (thinking, predict) and conviction( to communicate the thinking)

Based from Prof Katagiri from Japans, mathematics consist of 3 aspects:

1. Mathematical attitude

Mathematical attitude is positive thinking, have a question, have a critical when study mathematics.

2. Mathematical method

The mathematical method is :

a. Deduction

Deduction is a method to take a conclusion from general to specific.

b. Induction

Induction is a method to take a conclusion from specific to general.

c. Syllogism

example:

Premise 1 : I am a UNY student

premise 2 : all UNY student have a student card

conclusion : I have a student card.

d. Logic

logic is a knowledge to learn the principle of reflections and take the valid conclusion.

e. Prove

3. Mathematical content

Kinds of the object of mathematics:

a. Formal object: deductive method, inductive method, syllogism method, logic, prove

b. Material object: thinking object, learning based on the ages.

The power of mathematics is critical thinking.

The meaning of mathematics is realistic mathematics:

1. Horizontal mathematics

2. Vertical mathematics

It is my writing about mathematics and its characteristics. I hope I will be useful for the readers. I hope you can see that mathematics is not a simple thing.

AN INTRODUCTION TO BAHASA INGGRIS II

Last week I had a first meeting English lesson II. For this semester the lecturer is Mr. Marsigit. He is very interesting and nice. He graduated from London university in 1996. He went to Japan at the first time in 2000. Now, he can go to Japan to join some meetings annually.

Last week, he explained that this semester’s exercices must be written at our blogs. Because it is formal blog, so we must fill our blog with formal photos and writings. And the most important thing is don’t make any plagiatism. Our blog must be his blog’s follower at http://marsigitenglish.blogspot.com. But it’s his second blog. His main blog is http://powermathematics.blogspot.com. In his main blog, he wrote elegies/sad songs about students, lecturers and teachers’ condition. But this writing can’t be understood easily by common people.

There are 5 points to study English well:

1. Motivation

Motivation is very important. If we don’t have motivation, we can’t understand the lesson well. From right now, we must love English language and don’t be afraid to start to do something. Motivation is not only willingness, but also our feeling, happiness, our focus and our belief that we can. Motivation can help us to love English and make us more bravier to practice our ability.

2. Attitude

Our attitude to English must be good. We must think that English is very important.so, we should make some tactics to study English.

3. Understanding

Knowing English is needed to built our ability. With knowing, we can learn English easily. We can start from knowing the structures, grammars etc. We also must be responsible with our way. If we understand others, we can work with other friends easily.

4. Skill

Our speaking skill influence English learning. Skill can be increased with using it in our daily life.

5. Experience

Experience can make us better. It can help us to learn the wrong and the right. So, we must try to practice our skill. Then we will be experienced with English.

Those are some tips to reach your success in learning English. It’s enough and sorry for my mistakes.
