The Fibonacci sequence, also known as the Split Sequence, refers to such a sequence 、...Mathematically, the Fibonacci sequence is defined recursively as follows: f0=0, f1=1, fn=f(n-1)+f(n-2)(n>=2, n n*) In modern physics, quasicrystalline structure, chemistry and other fields, the Fibonacci sequence has direct applications, for this reason, the American Mathematical Society has published the quarterly journal "Fibonacci Sequence" since the 1960s, which is dedicated to publishing research results in this area.
The Fibonacci sequence refers to such a sequence of numbersThis sequence starts with the third term, each of which is equal to the sum of the first two terms. The characteristic equation for the linear recursive sequence is:
x 2=x+1 gives x1=(1+ 5) 2,,x2=(1- 5) 2. Then f(n)=c1*x1 n + c2*x2 n. ∵f(1)=f(2)=1。
c1*x1 + c2*x2。 c1*x1^2 + c2*x2^2。The solution yields c1 = 5 5 and c2 = - 5 5.
f(n)=( 5 5)*(5 means root number 5). If there is anything you don't understand, check the encyclopedia.

Pay attention to learning methods, pay attention to the connection between knowledge points, accumulate wrong questions, do more exercises, these need to be persistent, there is no way to improve quickly, unless you sign up for a class.
-
There is no shortcut to learning, rely on perseverance.
-
The current score does not mean the final exam, look at the last, parents should encourage more, and the problem cannot be solved in a hurry.
-
It is recommended that you go directly to an intermediary! Trouble-free, such as the first act (international education) and the like.
-
The preliminary round is all fill-in-the-blank questions. It's simpler. It's a school-wide test.
Then the semi-finals are a choice to fill in the blanks and a few big questions. Very difficult to do. It's better to be able to get a few questions right. It was selected from the preliminary round to take the test.
Only the results of the semi-finals are valid. to get the prize.

1. Junior high school is junior high school, and high school is high school, and when you see the connection between the two in learning, you must see the difference between the two. High school is mainly based on self-study, teachers have their own rhythm, as students, we should have our own arrangements, preview, review, do questions, ask questions, we must take the initiative by ourselves, not be led by the teacher.
2. There is also the need to distinguish the connection between self and others, not only to see the development trend of oneself and the development trend of others, but also to see the spiral of things in the south and the north;
3. There are many reasons, and finding yourself is always the most important, because you stop moving forward and others go to a higher place, and if you don't advance against the current, you will retreat. I'm glad you see your own shortcomings, you have to be confident, your opponent's biggest thing is not to face the people around you but yourself, I have a lot of classmates who had good grades at the time and finally lost themselves in the college entrance examination;
4. Stabilize the position, constantly regain self-confidence, establish goals, clarify goals and make reasonable plans, those who have mastered do not have to be old to do questions, the key is not to understand, to do not know, not to understand, to remember, to do the wrong repeatedly, to deepen the impression. Live every day to the fullest.
5. If you are a boy, pay attention to your body, have the desire to vent reasonably through fitness exercise, pay attention to your diet, maintain a peaceful attitude, do not be sad or happy, no matter how the environment changes, you must have your own backbone.
6. Things are not worse, we must take advantage of the current advantages and continue to work hard, and it will definitely be better.

Landlord, you are strikingly similar to me! I was basically in the top 50 in Yizheng City, Jiangsu Province in junior high school, especially in mathematics, and was admitted to the provincial recruitment experimental class of the best high school in Jiangsu at that time.
Looking back now, I think we should have a correct mentality: first, learning is not the only one, exams are not the only one, successful people in the future are not necessarily good grades, good grades can often only be professors to do research (I am at the same table at Tsinghua University, he has already been ready to become a professor), of course, I do not deny that people who study well have a special single-minded spirit; So, second, you have to be single-minded, for example, if you want to take the college entrance examination (I mean that at that time, some people engaged in competitions, and some people engaged in independent enrollment, I just messed around, and I always wanted to get involved in what others did, and the whole person was messed up), you should focus on the college entrance examination from now on, which courses in the college entrance examination, and all your thoughts revolve around the college entrance examination; Third, people are more popular than people, the people around you can be said to be the best, think about it, what kind of people you met before, what level are they now, obviously different, don't compare with them, just do your best; Fourth, in fact, this kind of pressure is only good for you, there is no harm, I used to have the worst English, it can be said that every time I was the first from the bottom of the class, often less than a dozen points less than the second-to-last, I was really sad at the time, my heart was like ashes, the English teacher was still the class teacher, but now, English is just my best one, it's really unbelievable, the sixth-level naked test (really naked, unlike others who buy papers to do) qingsong passed; Fifth, in fact, when I really work, I don't need a lot of knowledge above high school, often the knowledge of junior high school is enough, and the real turning point in life is not the college entrance examination, but the positioning of my future work, I am, I am now in a low-stream 985 student biology major, if I choose again, I would rather choose a 211 even if the province is not a 211 communication or computer major, if you are good at communication can do sales, doing well is really much better than doing research, and this has nothing to do with academic qualifications.
In short, be calm and do what you want to do, and everything will fall into place.
Thinking about it before, I was really messy and sad, a math competition, a physics competition, an independent enrollment, I also repeated a year before I went to 985, and I was still 7 points away from the second book. If it weren't for the fact that I have a special sense of guilt about my years of study, I really feel that there is no need to repeat it, and I will go directly to a good major in the province, and there will be nothing bad about going to graduate school or working in the future. Life should be more peaceful!

What should I do if my grades in high school have dropped badly?
-
I'm also similar to you, junior high school is very good, to the key high school is a little powerless, but I am more optimistic, and I have never felt that I have anything inferior to others, everyone has different talents, and the path to choose in the future is also different, not that you can't learn well at the moment means that you can't find a good job in the future, I think the most important thing is to work hard, worthy of your own efforts, instead of complaining about the world, while wasting time, just work hard!
-
First, find out the reason for the decline in grades. Whether it is the wrong learning method, not enough time to study, or the wrong learning mentality or other factors interfere, this point must be clarified, that is, to find the symptoms. Second, we must prescribe the right medicine.

Do your best to obey the destiny of God, be at peace with what happens, don't put too much pressure on yourself, and live happily.

Liberal Arts or Science?
The liberal arts mainly rely on the back, and the science mainly relies on writing questions.
And you have to believe in yourself, you can't lose faith, you have to always believe that you're the best
-
People just have to keep working hard. Do your best.

Grasp your own mentality, don't always think of yourself as your former self, put yourself a little lower, don't always think about regaining your first place, so that the psychological pressure will be too great, you have always been at the top of the grades, you may be knocked down by a failure, because you are not used to it, there is no such anti-pressure, and the psychology expects too much from yourself. So in my opinion, you must first lower your positioning and adjust your mentality, so that you can settle down and study patiently and calmly. Also, it may be that there is a problem with your learning method, so if you can, after each test, pay attention to find your weaknesses, why did you make mistakes, is it a problem of knowledge, a problem of performance or a problem of skills?
Again, hard work does not necessarily pay off, reading is also about talent, some people used to read books, when it was critical, it was not uncommon to work hard to catch up, especially boys, many, explosive, some people just don't have explosiveness. Therefore, pay attention to your own accumulation, usually have good grades, and don't fail in the college entrance examination too much. Why, because you have to know that the one-time test of the college entrance examination, it is extremely important to play on the spot, so if you don't take the college entrance examination, don't give up, every day's progress is the basis for the success of the college entrance examination, take every step, go yourself, don't always care about comparing with others, you can't compare, it's meaningless, lose all your distractions, is the first thing you have to do now.

Repeat the various types of questions left by the teacher

The blind gods of the school tyrants are staring at what they are doing!

If you want to go to a public high school, you may not be able to go to a public high school, but have you filled in some private high schools? Some private high schools are also good, and the score line is much lower. I took the high school entrance exam last year.

Good study methods are certainly useful.
But everyone's situation is different.
You didn't even say what you were doing.
Not every approach will work for you.
Yes, there are still a lot of repeaters if the score of the general high school is not enough. However, the employment prospects are not very good if you go to general high school, and if your child is interested in technology, it is also good to learn a popular technology.
Of course, it's high school, and technical school doesn't even think about it. >>>More
