Layout design of mathematical handwritten newspaper

Layout design of mathematical handwritten newspaper

In school, handwritten newspaper is a good activity form in the second class, which is quite flexible and free. Manuscript newspaper is also a kind of mass propaganda tool. Equivalent to a smaller version of the blackboard newspaper. Below I will bring you the layout of the mathematical handwritten newspaper for reference only, hoping to help you.

Mathematical Manuscripts Part I: Fibonacci Sequence and Golden Section

Interestingly, such a series of numbers are completely natural, but the general formula is expressed by irrational numbers. Moreover, when n tends to infinity, the ratio of the latter term to the former term approaches the golden section of 0.6 18 (or the fractional part of the ratio of the latter term to the former term approaches the golden section of 0.6 18, and the ratio of the former term to the latter term approaches the golden section of 0.6 18).

1÷ 1= 1,2÷ 1=2,3÷2= 1.5,5÷3= 1.666...,8÷5= 1.6,…………,89÷55= 1.6 18 18 18…, …………233÷ 144= 1.6 18055…75025÷46368= 1.6 180339889… ...

The later, the closer these ratios are to the golden ratio.

certificate

a[n+2]=a[n+ 1]+a[n].

Divide both sides by a[n+ 1] to get:

a[n+2]/a[n+ 1]= 1 .

If the limit of a[n+ 1]/a[n] exists, let its limit be x,

Then lim [n->; ; ; ∞](a[n+2]/a[n+ 1])=lim[n->； ; ∞](a[n+ 1]/a[n])=x .

So x =1+1/x.

That is x=x+ 1.

So the limit is the golden ratio.

Mathematical Manuscript II: The Story of the Number 0

About 1500 years ago, European mathematicians did not know how to use "0". They use Roman numerals. Roman numerals are symbols representing numbers, which are combined to represent different numbers according to certain rules. When using this number, the number "0" is not needed.

At that time, a scholar of the Roman Empire discovered the symbol "0" from Indian notation. He found it very convenient to use "0" for mathematical operation, and he was very happy. He also introduced the Indian method of "0" to everyone. After a while, it was known by the pope at that time. At that time, it was the Middle Ages in Europe. The power of the church was very strong, and the power of the pope far exceeded that of the emperor. The Pope was very angry. He rebuked that the sacred number was created by God, and there was no such monster as "0" in the number created by God. Anyone who wants to introduce now is blasphemous! So the Pope ordered the scholar to be arrested and tortured, and his ten fingers were tightly clamped with a clamp, so that his hand was disabled and he could no longer write with a pen. In this way, "0" was banned by the ignorant and cruel Pope.

However, although the use of "0" is forbidden, Roman mathematicians still use "0" secretly in mathematical research regardless of the ban, and still make a lot of mathematical contributions with "0". Later, "0" was finally widely used in Europe, but Roman numerals were gradually eliminated.

Math manuscript 3: I think everyone knows math, have they all been exposed to it? Math can be used anywhere. Don't you think math is interesting?

Mathematics can be used to buy food, clothes and things. Even the Rubik's cube can use mathematics, because turning the Rubik's cube requires mathematical formulas! And the national economic development also needs mathematics. ...

Tell a story about me and math: when I was a child, my father often taught me math, and I studied numbers, such as 1- 10. If someone asks me eleven, I will ask, "What is eleven? October 1st? " Dad wrote it on paper and asked me orally: three or four? I looked at the two numbers on the paper. Of course, I look at strokes. I think they are bigger. I said three and my father burst out laughing. After laughing, he said, "silly boy, it's four!" " "Dad also taught me subtraction and addition. Of course not, within ten. After that, I can tell which is bigger and which is smaller. Once, my mother gave my father three apples, but she gave me two. I said angrily, "It's not fair! I am not as good as my father. " Helpless, my mother had to give me another apple.

In the first grade, we learned to carry and learn what we should learn when shopping. Once, I went to buy ice cream to eat. I gave my boss 50 yuan and ice cream 8 yuan, but my boss gave me 44 yuan. I worked out 42 yuan by subtraction. I immediately ran back and said, "Boss, it's 42 yuan, not 44 yuan!" " The boss calculated and said, "Yes. Thank you. " I smiled.

I've learned a lot of knowledge, all about mathematics, and it also connects with the reality of life, which makes me feel that mathematics is very useful, don't you think?
