一天終于結(jié)束了,我相信大家都是有收獲的,這時候十分有必須要寫一篇日記了。是不是無從下筆、沒有頭緒?以下是小編整理的高中英語作文:數(shù)學(xué)日記,僅供參考,希望能夠幫助到大家。
Cornerstone
Today we mainly learn the fractal algorithm, significance and some computing laws regarding fraction division.
First, we started from a topic u0026 “ Xiao Ming 2/3 hours walked 2km, Xiaoming How many meters per hour? u0026 ” we can understand from the question: This question requires small speed, depending on the speed u003d distance / time, it can directly list the equation 2 divided by 2/3. , List the calculation, below is calculated. According to: a number of times with (not 0), it is equivalent to multiplying the countdown. The result is 3. So what is its meaning? My heart produces such a question u0026 " Why do you have to change the countdown? u0026 ” I use a number of binding methods to understand its allegation: 2/3 hours of 2 1/3 hours. For 1/3 hours of walking distance, seeking 3 1/3 hours (ie 1 hour) away, the column is 2 * 1/2 * 3, 1/2 * 3/2. I suddenly realized.
When calculating the fraction division, the component multiplication is to be calculated. If our score multiplication is made, the calculation of fractions is much easier. It can be seen that the cornerstone of learning is the beginning of the learning trip. u0026 “ water into the sea, the land is mountain u0026 ” each small detail is firm and is the beginning of success. From now on, I have to lay the cornerstone of the score, like a house, which can lay a good foundation for the next four years of junior high school mathematics!
Then, I studied the relationship between the divisor and the divisor of the division, found that three cases (1) is more than the divisor, and (2) the commercial division (3) is equal to the divided number. In response to these three cases, I repeatedly verified, discovering the following rules: When the divisor is greater than 1, the company is less than the divided; when the divisor is less than 1, the merchant is greater than the divided; when the divisor is equal to 1, the merchant is equal to the divided number. Pay attention to the divisor is not 0.
I also found that the rules of fractional division and score multiplication are just the opposite, because: a number of (not 0), equal to the countdown of it. So they have the opposite of their laws.
Only have a good job of learning the cornerstone, and later learns naturally, from today, I have to work hard to learn the cornerstone of myself!
