How to learn high school math! Ask High School Math!

First, find someone who is willing to help you with tutoring, and then, carefully complete the after-class exercises, the after-class exercises are more basic, targeted, check the answers after doing it, and insist on doing it every day, persist for a period of time You will find that mathematics has improved greatly, the key is personal efforts, come on!

Flip through textbooks, from the first year of junior high school to the third year of high school. Page by page, mathematics is difficult to make up. It's very difficult to make up, just ask if you don't understand, and you're not afraid of losing face. I'm afraid of losing face now, and I'm even more embarrassed in the future.

There's no good way to do it. What you accumulate slowly; In a hurry. You have to start with the problems you don't know, and use the questions to bring knowledge and methods; This will be faster than if you do it all over again, and finally, do more problems and reflect after solving them, this is mathematics. (I am a senior mathematics teacher at a key middle school,).

Go to the teacher to make up the lesson. There is no other way, as long as you are sincere, I believe that there is no teacher who will not agree. Don't be afraid of losing face.

The most important thing in learning mathematics is to understand the formulas and definitions in the textbook, do some questions appropriately, and score more than 130 points in the test, but like me, I will only deduct about 10 points.

Do more questions, summarize more, and practice will naturally make perfect.

It's hard to chase after so much math falls, but as long as you can persevere, look at it, and persist in it, you will definitely be able to do it!

First of all, let's pick up the junior high school book and read it from beginning to end, be careful, don't pass by with it, mathematics is a link!

After getting these, let's take a look at the tutorial book that is 1 2 higher than the number of words has reached the upper limit, not much to say.

From now on, don't be blind, ask more questions, ask simple sentimental questions, ask classmates frequently, understand one when you meet one, and slowly you should be able to do it.

I came back 20 minutes early, which means that the car drove 20 less during the journey. Round trip back and forth, so in the process of going, 10 minutes less driving, all daughters walk time 50-20 2 = 40 minutes. 2.

1) If all are cut according to the specifications of 77cm, the number of parts that can be reached is 600 77 take the whole number, which is 7, and the remaining length is 61cm. But 88cm specifications.

Another group of junior high school students are about to enter the high school classroom, and high school mathematics is more cumbersome and more difficult than junior high school mathematics, mainly because high school mathematics concepts are more abstract, there are many exercises and the teaching density is also large, so many students will retreat from the subject of mathematics after entering the first year of high school, and even lose confidence. Here I will talk about the effective mathematics learning methods for students to learn from, mathematics is not a knowledge, empirical subject, but a thinking subject. Therefore, the study of mathematics focuses on cultivating the ability to observe, analyze and reason, and develop learners' creative ability and innovative thinking. Therefore, in the process of learning mathematics, it is necessary to consciously cultivate these abilities.

This will lead to an effective breakthrough in math achievement.

If you want to learn to learn, you must not only learn good learning methods from others, but also be good at summarizing your own learning methods. If you learn mathematics, you need to think independently, analyze the problem in depth, and get to the point where you understand it well, then you will definitely achieve excellent results.

Collect the mistakes you have made, correct them and write down the reasons for them; For test scores, set a goal within your ability; Reasonable schedule and good study habits can help to achieve stable academic performance.

Be sure to do a good job of pre-study, and walk into class with the questions in the preview, so that you can get twice the result with half the effort; Double-check when you finish your homework; The exercises required by the teacher should be completed carefully.

There is no genius who can learn mathematics well with less writing, so you should do more exercises in your spare time, and you will definitely gain something from the mentality that practice makes perfect.

The strategy for math exams is very important. The questions in the exam are generally easy first and then difficult, so you should grasp the relatively simple questions in front of you, try not to lose points, and then do the difficult questions in the remaining time. Accuracy is just as important as speed of doing the questions, and giving up certain questions wisely can help you perform at your normal level and help you achieve the desired results on the exam.

It is impossible to escape the content of the exam. You have to remember.

Even if the last question is the score of the extra interest question, this question is all wrong, whether it is 100 points or 120 points, it is a passing grade.

So, for calculus and the like, you still have to take the time to memorize some important formulas, which can't be helped.

Permutations and combinations, if you really do it, it doesn't matter, permutations and combinations only account for a small part of the high numbers. And it's all fill-in-the-blank questions, not the last big questions.

For the differential integration of space geometry, there are too few practical applications in life. The so-called learning is to use, and after learning, you will use it immediately. In this case, you have to work hard to see the type of question, in the face of it, there is nothing wrong with the calculation, some of the problems seem to be geometric problems, but they are actually function problems, about this, it is the place where the trick comes out, you must see through the essence of the problem at a glance.

This has a lot to do with training.

It is recommended that you usually spend more time on math, and you can read less in other courses, which is exactly that sentence: you have tried hard, or failed, but you have done your best! Nothing will be a desperate way, and it is impossible for people to make money and eat with rice only by high numbers.

The weaknesses and shortcomings of one just prove that he has amazing strengths somewhere. Absolutely.

Classmates, we are a kind of people, I can't learn math well in high school, my mother asked me to make up for classes, I think it's better to study on my own, sort out the test papers I have done before, and analyze the wrong questions by myself, it should be helpful.

Take the textbook as the main thing, one step at a time! The key is the definitions, theorems, and formulas, and if you remember them, you will be able to answer the math problems and draw inferences. Mathematical Methods Note:

Mathematical induction, counter-proof, design but not seeking method, problem solving method pay attention to the special value method, conjecture verification method, elimination method, etc., high school is OK. If you have the heart to improve, you can communicate with your brother, absolutely sincere!

There are four points A, B, C, D on a sphere with radius R, and the quadrilateral ABCD is a square with an edge length of R, is there a point P on the sphere so that the volume of the pyramid P and ABCD is the cube of half r? If so, determine the location of the point; If not, please explain why.

Analysis: There are four points A, B, C, D on a sphere with radius R, and the quadrilateral ABCD is a square with an edge length R.

s(abcd)=r^2

Let there be a point p on the sphere

V(P-ABCD)=1 3R 2*H=R 3 2==>H=3R 2 As shown in the figure: this figure is the ball O, the section of the AC along the bottom ABCD diagonal AC is the bottom ABCD diagonal, and the distance from the surface A'B'C'D' to the surface ABCD is 3R2

Then the point p is on a circle with h as the center and ha' as the radius, and this circle is perpendicular to the diameter of the sphere o fg

The specific idea can be explained in this way.

The quadrangular pyramid is reduced to a quadrangular prism (the column is 3 times the size of the vertebrae of the same height and bottom), and the height is obtained by knowing the volume and base area.

The position of the point is then determined according to the height.

The positions of all the points that meet the conditions must form a circle.

exists, the side length of the square ABCD is R, the diagonal is the root number 2*R, and the height of the pyramid is H according to the volume

That is, 1 3r 2*h=r 3 2 to get h=3 2r, then you need to determine whether there is a h point on the ball, so that h=3 2r

You can draw a flat circle.

That is, whether r + root number 2*r is greater than 3 2r

The result is greater than!
