The first n terms of geometric series and formula geometric series refer to the series in which the ratio of each term to its previous term is equal to the same constant from the second term, usually expressed by G and P. This constant is called the common ratio of geometric series, usually expressed by the letter Q (q≠0), and the geometric series is a 1≠0. Where each item in {an} is not 0. Note: When q= 1, an is a constant series.
How to use the first n terms and formulas of geometric series
How to learn high school mathematics well
1. Read your notes before you do your homework.
The teacher understood it as soon as he said it, but he couldn't do it himself. This is a problem that many people have. There is a strange phenomenon that teachers always compare their students' level with their own. He thinks everyone knows, but in fact many people don't. Therefore, in the practice after class, most students still look at a loss and are at a loss.
Remember to review before you do the exercises after class. The so-called review is to read the textbook and review the notes. Only in this way can we have a clear train of thought, otherwise the problems are basically in fog, wasting time and failing to improve our grades. In the homework after class, try to read the textbook thoroughly, and don't blindly do extracurricular questions, otherwise you will end up dropping out of school, unable to land, and your exam results will be a mess!
2. Strengthen reflection after doing the questions
After all, the usual study is not as stressful as the college entrance examination, so we must learn a good learning method and problem-solving ideas in the usual exercise. You should be good at summing up. After all, senior one still needs to accumulate knowledge and methods. If you persist in doing this, your grades in senior three will certainly advance by leaps and bounds, and it will not be a problem to be admitted to a good university.
Review and summarize
The way of learning is different from before. There used to be a lot of passive learning, and the teacher helped you do it. You just have to wait for memory, but high school is a period of active learning. Therefore, no matter what the teacher says, you should review yourself and summarize your learning methods. This is the highest state of learning.
4. Be brave in correcting mistakes
Everyone makes mistakes, but it is brave and commendable to make mistakes and correct them. The terrible thing is that some people always make mistakes and make the same mistakes, so they can't be forgiven.
5. The wrong problem reappears.
Wrong questions are also common, whether it is a unit exam or a monthly exam, as long as there are wrong questions, remember to sort them out, because all mistakes can be sorted out, and you can review them several times at the end of the term, especially in the college entrance examination. These wrong questions are treasures.
read
Many people don't understand this. What is the relationship between mathematics and reading? Actually, it's not. Mathematics is mainly about examining questions. If the Chinese reading comprehension ability is not good, how to examine the questions? You have no idea what this means. Therefore, reading is directly related to science.
Reading can not only increase your knowledge, but also your experience. Of course, the most direct thing is to improve your grades in other subjects. Therefore, extracurricular reading is particularly important. Although you are studying, you should also read classic books, instead of just finding a few online novels to read. Don't waste time on books without nutrition.
7. Reasonable study plan
A good plan can be half successful in advance. Many people are blind in their studies. If they want to make rapid progress in their studies, they still need a detailed study plan, which is reasonable and suitable for them, instead of finding a person's study plan at random and then implementing it. Everyone's situation is different, so we should specify a feasible scheme according to our actual situation. We must resolutely implement it in order to achieve great success.
