How to be serious about the speed of the math test, and how can I improve the speed when taking the

I'm also about to pass the high school entrance exam. I don't know how difficult it is for you to take the high school entrance exam, but I can give you some advice:

Pay attention to the speed. Regardless of any subject (in fact, I think math is the most time-consuming, there are less than 20 minutes left to finish each time), it is important to ensure a certain speed, otherwise it will be worth losing marks if you don't finish writing. Of course, you don't seem to be a problem of not being able to finish writing, but a question of what to calculate, so you have to ensure the speed of some choices in the front, fill in the blanks, etc., and write the process quickly, and the time will be relatively abundant in the back, and you can solve the equation or something seriously.

You know, what the questioner thinks is that solving the equation is a scoring problem, so it can't be done if it's wrong. But the speed can't be too fast, too fast can not guarantee the accuracy rate, we have a girl who writes her homework quickly, but her grades have not been up. It must be fast and right, this is the effect of "speeding up".

Pay attention to the review questions. Some of the questions are very long, but you must also read them carefully, and you can find the right conditions in the questions. Not to mention that it takes time to look at the questions carefully, in April, there are several students in our class who are usually good at math and are not very good in the exam, why?

The penultimate question is longer, and there is a key sentence in the question, many people don't see it, and the consequence is that in order to save a minute of reading time, the 12-point question is basically wiped out. I also once saw that the carton also had quality in physics, and it seemed that I only got 2 points for the 8-point question. The review is really crucial, don't skimp on the 1 minute or so.

Look at the problem from the point of view of the person who wrote the question. When you see the question, you need to know which knowledge point the questioner wants to test, and he thinks that this question is a score or a gap. Of course, you don't need to be like this for every question, just think about some of the more tangled questions.

This requires a high level of ability, and first of all, you have to have a firm grasp of the relevant knowledge. There is still a month, and if you don't master it, check and fill in the gaps!

Another thing to say is to adjust your mentality, believe in yourself, don't be upset when you encounter problems, calm down, and don't keep thinking about it, thinking about it for 10 minutes and feeling really not going to jump. A good body is also very important, and the body is the capital of the revolution! Don't ask another question as soon as you're done with this question and what you've written, it's a waste of time and makes you more nervous – when you know you've made a mistake.

That's all I can say, believe in yourself.

I wish you all the best in the high school entrance examination! No pain, no gain!

Be serious about the exam.

Relax and double-check after the exam.

Solving an equation allows you to substitute the result into the original equation.

The results are not equal.

Please relax during the exam, too much tension will cause you psychological stress and lead to mistakes.

Don't think too much about other things during the exam, put your whole mind on the exam and don't think about it.

If you want to make sure you don't make mistakes, you should be careful when you do the questions, or check them several times after doing them, and it will only take a minute or two at most.

Good luck with the exams.

After going to the exam room, write down the things that you are prone to miss on the straw paper, such as don't forget the proof of the triangle, read the questions twice or three times when doing the application questions, and so on.

If you want to improve your math scores, in addition to doing a lot of problems, it is more important to induct. You should find out all the previous questions during the holidays, Saturdays and Sundays, organize the questions you did wrong into a notebook, read them often, and memorize them in your head, and strive not to make the same mistakes again in the future.

Improve the efficiency of problem solving. When you come across a problem that you can't solve for a long time, don't waste time and skip it, but you have to do it when you get home.

Usually do the exercises, those questions that are not accurate or do not understand the front of the circle in front of the circle, wait until the teacher speaks carefully, and when reviewing in the future, those that are particularly simple and can be done with your eyes closed do not look at it again, just look at the questions circled by yourself, which not only improves efficiency but also does not waste time.

PS: It's my own method, it's still more useful for me, if you want to improve your grades, you have to put in an exponential effort, don't just talk about it. I believe that as long as you work hard, you will be able to, come on, come on, come on!

Familiarity with mathematics and the types of questions on the test is the key to improving the speed of answering questions in the mathematics test.

As with any subject, familiarity with the content of the knowledge is a prerequisite. During the exam, the teacher tests whether the students can understand the meaning of the questions, and can integrate all aspects of knowledge and problem-solving methods. Therefore, in the usual learning process, it should be fully mastered, thoroughly understood, and through a lot of practice, this part of the knowledge should be firmly mastered, and lay the foundation for the next step of knowledge.

Practice makes perfect". Adequate practice of the learning content can help students form ideas for solving problems in the shortest possible time, and can help them roughly judge whether their solutions are correct during the examination process. For example, if the result of a question is a very strange value, too large, too small, or very different from the usual question, and the proof question has entered a very complicated point, etc., it means that there may be a mistake in one of them.

It is a skill to do familiar questions first, so that the questions that you don't know or the time-consuming questions don't occupy the rest of the answering time. The most important thing in this regard is to master the correct way to answer the questions. You should not pick up the paper and do it, but review the questions first, read the whole paper roughly, and start with the most confident questions.

This leaves the most time for the big problems that follow. There are also how to choose the formula to solve the problem when doing the problem (there is often more than one formula that can solve the problem correctly, but often only one is the most concise), as an auxiliary line, using simple algorithms (such as flexible reduction), the appropriate deformation and application of the basic formula, etc., all of which should be cultivated in the course of a lot of practice in the usual time.

It is important to get into the habit of keeping pages tidy when writing from your daily work, and you can save time by reducing scribbling and erasing. In the event of an error, a stroke of two horizontal bars can clearly indicate that "this part is wrong". It can also leave candidates with a final comparison and review before handing in the paper.

If you find that the new part is wrong, and you want to go back to the original crossed-out part, you can cross out the later part, use the checkmark and text to prompt "this answer shall prevail", and so on.

Another important part of the habit of doing the problem is to try to write down each step of the problem. Some students think that this is too time-consuming, and they always want to write the answer quickly and be done, but they don't know that the process of writing and solving the problem can be carried out at the same time as thinking. In this way, the first few steps of the answer to the question have also been written down when the thinking is mature, which is a reference for further analysis, especially for complex problem solving or lengthy problem verification process, writing the previous results is of great help to the later.

What's more, if a question consists of several steps, each step here will be of concern to the teacher. If you simply write down one answer, if you make a mistake (such as a clerical error, etc.), you will get all the questions wrong and you won't get a single point. And if there are the first few steps for the teacher to correct, as long as they are correct, most of the points in this question can be obtained.

In short, "comprehension", "proficiency", "integration" and "good habits" are the keys to substantially improving the speed of answering questions in mathematics exams.

1. Set yourself some time limits. It is easy to get bored by studying for a long time, so you can divide the homework into several parts, and set a time limit for each part, such as completing the exercise within an hour, completing the test before 8 o'clock, etc., which will not only help improve efficiency, but also do not cause fatigue. If possible, gradually reduce the time it takes, and soon you will find that what used to be an hour away can now be done in forty minutes.

2. Don't do other things or think about other things while studying. Everyone understands the truth that one mind cannot be used for two purposes, but there are still many students who are listening while studying**. You may say that listening is a good way to relax your nerves, so you can concentrate on studying for an hour and then relax and listen for a quarter of an hour**, which is much better than doing homework with headphones.

3. Don't review the same subject all night. I used to watch math or physics at night, and it proved that it was not only exhausting, but also ineffective. Later, I arranged to review two or three homework every night, and the situation was much better.

Except for the very important content, you don't have to take detailed notes in class. If you are busy taking notes in class, you will not be able to listen to the lecture efficiently, and you can't guarantee that you will read your notes after class. The main work done in class should be to digest and absorb the teacher's lectures, and make some brief notes appropriately.

Fill-in-the-blank questions do not require a solution process, do not need real disintegration ideas, and when there are x,n and the like in the known conditions, substituting 1,0 is likely to have a miraculous effect.

Multiple choice questions, substitute the options, as long as you can determine that it is wrong, you don't need to figure out why it is right. (That's the task after the exam).

Answer questions, skip the questions without ideas decisively, and do the latter first, it is very likely that the latter will be simpler.

If you don't finish the question in the end, you can take the time to write down the formulas and solutions that may be used, and you will also be scored.

The sea of questions tactic can effectively improve the speed of doing questions, but more importantly, we must learn to summarize and take our time, not all at once.

My math teacher always emphasized that the draft should be standardized, like classwork, so that the ideas are easier to sort out.

Usually do more calculations to improve your computing ability, so that the exam will be faster, because a lot of math exams are related to calculations, and it can be said that if you don't have good computing skills, you can't learn math well.

Those who can do it first, and those who can't wait first.

The most important thing is that the basics have not kept up, such as computing power, measurement methods, etc., which is mainly the reason for the underdevelopment of the cerebellum. We should do more basic knowledge, more calculation ability, develop the cerebellum, and drive the rotational speed.

Answer: The correct rate of math questions is high, but the speed cannot keep up, it may be because you usually do too few questions, and you usually do not practice much for similar questions.

Unproficient in the topic, inaccurate grasp of knowledge points, unclear ideas for problem solving, and insufficient analytical ability; You need to keep exercising yourself, so that you can integrate the knowledge points and draw inferences from one another.

When you get home, you have to make a habit to review the textbooks and notebooks, prepare the raw materials first, and then, it doesn't matter if you do it slowly for the first time, the more you do it, the faster you will be able to do it, as long as you stick to two steps, the speed of doing math problems will definitely increase.

The center of the circle (1,1), radius r=1

The distance from the center of the circle to the tangent is equal to the radius.

If the tangent slope does not exist.

then the perpendicular x-axis, and through p then x=2

1,1) to x=2 from the distance = |1-2|=1=r, true.

So x=2 is the tangent.

If the tangent oblique dust finch rate exists early.

then y-3=k(x-2).

kx-y-2k+3=0

1,1) to tangent distance = |k*1-1-2k+3|/√k^2+1)=1k-2|=√k^2+1)

Square on both sides. k^2-4k+4=k^2+1

k=3/43x-4y+6=0

So the tangent is x-2=0 and 3x-4y+6=0

Let the tangent equation be y=kx+b

Bring (into the above formula.)

3=2k+b

i.e. b = 3-2k

The coordinates of the center of the circle are (

The radius is 1

The distance to the Chetan Chain is 1

Absolute value of k-1+b) = absolute value of 1(2-k) = (k2+1).

4-4k+k2=k2+1

k=3/4b=3/2

The tangent equation is y=3x 4+3 2 looks!

Practice more, and you will be prepared for the exam.

Postgraduate mathematics relies on the accumulation of skills.

Usually do more questions, and listen to lectures in class.

1.You can first figure out the meaning of the topic, find out the key sentences, and figure out the quantitative relationship2Columnar calculations.

3.After the data is calculated, the calculation is checked and compared.

Thank you, hope it helps.

Solid basic knowledge, careful problem-solving habits, proficient problem-solving methods, and appropriate practice.

Read the questions carefully

Calculate carefully and do not be sloppy.

After doing it, check it several times

No errors are guaranteed.

Apparently f(x) is continuous in (-, and there are derivatives of the order, f'(x)=12x 3-24x 2+12x=12x(x-1) 2, let f'(x)=0, the station x1=0 is obtained; x2=1,f''(x) = 36x 2-48x + 12 = 12 (3x-1) (x-1) because f''(x1)=12>0, so f(x)z takes the minimum at x1=0; The minimum is f(0)=1;

Due to f''(x2)=0, so the second sufficient condition of the extreme value of the function cannot be used to determine whether x2 is an extreme point, but when x takes the values near the left and right sides of x2, there is f'(x) > 0, so according to the first sufficient condition of the extreme value of the function, we can see that f(x) has no extreme value at x2=1.
