How to Learn High School Mathematics Compulsory 2 Chapter 1 5

Find some topics.

Then divide all the geometry into modules. Then dedicate yourself to a module for a while, and when you think you can, move on to the next module.

When you think it's almost digested. Start doing some college entrance exam questions.

There are generally methods for analytic geometry, such as correlation point method, polar coordinate method, curve system method, coordinate subtraction method, and so on. As long as you are proficient in these common methods, analytic geometry is actually very simple.

Analytic geometry should keep in mind the properties of common curves, and the relevant conclusions.

Solid geometry is relatively simple, theorem inference is used well, and vectors can definitely be solved if you don't use vectors.

But the key to this kind of thing depends on yourself, guard against arrogance and rashness, take your time, it will be fine.

Structural features of columns, cones, tables, and balls.

Three-view and visual diagram of the spatial geometry.

1 Three views:

Front view: from front to back.

Side view: from left to right.

Top view: from top to bottom.

2 Principles of Drawing Three Views:

Long alignment, height alignment, width equal.

3. Intuitive drawing: oblique two measurement method.

4 Steps of oblique bimeter drawing:

1）.Lines parallel to the axis remain parallel to the axis;

2）.The length of the line parallel to the y-axis becomes halved, and the length of the line parallel to the x-axis and the z-axis remains unchanged.

3）.The drawing method should be well written.

5 The steps to draw a cuboid with oblique bigrammetry: (1) draw the axis (2) draw the bottom surface (3) draw the side edges (4) form the picture.

The surface area and volume of the space geometry.

a) The surface area of the space geometry.

1. Surface area of prism and pyramid: The sum of the area of each face.

2 The surface area of the cylinder.

3 Surface area of the cone.

4 Surface area of the round table.

5 The surface area of the ball.

b) The volume of the space geometry.

1. The volume of the cylinder.

2 The volume of the cone.

The volume of 3 units.

4. The volume of the sphere.

The ability to think in three-dimensional space depends entirely on one's own accumulation and exercise, just as people who listen to songs often have a much higher sensitivity to sound than those who do not do vocal exercises.

Play games, such as the cosmic sand table, which does not require you to be very tired, but you can improve your sense of space by playing.

Blindfolded, "blind" walking. The eyes feed back two-dimensional information, and when you close your eyes, you can only rely on your brain to simulate the surrounding environment, and blindfold your eyes for purposeful training, which has a strong improvement in your sense of space.

Paper molds, making paper molds for the improvement of the sense of space is also considerable. Manipulating the two-dimensional paper into a three-dimensional model will definitely improve your sense of space.

Read the textbook carefully, look at the example questions carefully, imagine more, and look at the pictures more. Actually, this part of the content is not very difficult.

Listen carefully in class and do homework carefully.

Compulsory 2 is a relatively basic part of the mind, which is not too difficult, and you can pay attention to the details.

Space geometry should pay attention to geometric theorems, there are many things that are applicable in the plane but not applicable in three-dimensional space, then some theorems will be used, and the proof of the theorem in detail is very important, which is also the basis for doing space geometry problems. If you grasp these basics, do more questions, and be more familiar with some question types, you will basically be OK.

Solid geometry should focus on cultivating spatial ability, the relationship between lines, surfaces and angles is more difficult to solve with three perpendicular lines, the relationship between circles and lines is easier to learn, do more point type bodies, see more point questions, and don't waste time on the type problems that will be done. To have a good spatial imagination, usually pay attention to thinking more and have the ability to imagine! Secondly, do more corresponding questions, which is actually very simple!

Good spatial imagination Transform spatial problems into plane problems as much as possible. Read the textbook carefully, look at the example questions carefully, imagine more, and look at the pictures. Actually, this part of the content is not very difficult.

The new version of Bizhou stupid repair II includes complex numbers, vectors, and solid geometry. Be sure to study this in advance, study a book of sails by yourself every day before class, and do some after-class exercises. Where the record won't.

Listen carefully in class. Complete the homework left by the teacher with quality and quantity after class. I have time to do some more extracurricular exercises.

Listen carefully to the lectures of Yuanling Laoqiao Hungry Master in class, take good notes, review the content that Teacher Hail Xiaoqi has said in time, and usually do more exercises and easy to make mistakes, so that you can learn the compulsory high school mathematics 2.

1) Prepare your homework before class.

2) Make good use of the evening self-study time.

3) Don't buy counseling books indiscriminately.

4) Ye Jing has to do the questions on each paper.

5) Learn to tidy up.

6) Learn to make good use of the rolls. Socks telling.

7) Have confidence in yourself.

8) Find a way to learn on your own.

To learn mathematics well, you need to have your own independent thinking.

You can't just follow the teacher, you must have your own learning buddies and learn the prescription leakage method.

Know that those are the weak parts of yourself.

If you want to learn the second Zen file of high school mathematics, then you must certify and listen to the lectures of the old scriptmaster, humbly ask for advice when you encounter questions that you don't know, ask Mr. Hongxixiao, brush up on the questions, and consolidate the basic knowledge.

The key to learning mathematics is to understand, understand the essence of the knowledge points well, and do more problems. Those who do not understand should consult teachers and classmates, and must understand it when they are in time, so that they can learn the follow-up courses in time. The first sedan.

Take notes in the textbook in class, and in your spare time, you can buy a suitable tutorial book for in-depth study. Set the right amount to do every day.

First of all, you need to understand what you are learning. All that's left is to keep practicing. The best way is to brush up on the questions, especially some college entrance examination questions, which are highly targeted.

Senior 2 Introduction] If you think of the three years of high school as a cross-country long-distance run, then the second year of high school is the middle of this long-distance run. Compared with the starting point, it has a lot less encouragement and expectation, and compared with the finish line, it has a lot less applause and cheers. It is a stage of lonely struggle, a stage of endurance, will, and self-control.

Function knowledge points].

1. Definitions and Definitions:

The independent variable x and the dependent variable y have the following relationship:

y=kx+b

In this case, y is said to be a primary function of x.

In particular, when b = 0, y is a proportional function of x.

That is: y=kx (k is constant, k≠0).

2. Properties of primary functions:

The change value is proportional to the change value of the corresponding x, and the ratio is k, i.e., y=kx+b (k is any real number b that is not zero, take any real number) 2When x=0, b is the intercept of the function on the y-axis.

3. Images and properties of primary functions:

1.Techniques and Graphics: Go through the following 3 steps.

1) Lists; 2) dotting;

3) Connecting lines, you can make an image of a function - a straight line. Therefore, an image that is a function only needs to know 2 points and connect them into a straight line. (Usually find the intersection of the function image with the x-axis and y-axis).

2.Properties: (1) Any point p(x,y) on a primary function satisfies the equation:

y=kx+b。The coordinates of the intersection of the primary function of the broad lead (2) with the y-axis are always (0,b), and the image of the proportional function with the x-axis always intersects (-b k,0) always crosses the origin.

b and the quadrant where the function image is located:

When k>0, a straight line must pass.

1. In the third quadrant, y increases with the increase of x;

When k0, a straight line must pass.

1 and 2 quadrants;

When b=0, the line passes through the origin.

When b0, the straight line only passes.

1. Three quadrants; When k

Compulsory 1 and 2 in high school textbooks are the content that everyone should learn, which belongs to the scope of the college entrance examination. Students should complete compulsory courses 1 and 2 in the first semester of their first year of high school. There are five textbooks for each of the compulsory high school textbooks, and the compulsory courses are the foundation of the entire high school learning and are the content that all students must take.

The content of Compulsory 1 and Compulsory 2 is different. The main content of Compulsory 1 is the concept of blind or celery sets and functions and basic elementary functions. The second compulsory course is mainly the preliminary three-dimensional geometry and the preliminary plane analytic geometry.

Main advantages: Since the 50s of the 20th century, although the syllabus of middle school mathematics has been revised many times, there is a common guiding ideology, which is to do a good job in the three basics. It is emphasized that a correct understanding of mathematical concepts is a prerequisite for mastering the basic knowledge of mathematics.

At present, the outstanding problem in mathematics teaching in China is that the correct understanding of mathematical concepts, that is, the mastery of mathematical foundations, is neglected.

Yes, high school math is compulsory.

1, 2, electives.

One, two, three.

There is the old college entrance examination, and there is also the new college entrance examination.

But the typography is different.

The content has changed slightly.

1。Be familiar with the theorem. You have to know what theorems are used to prove and how.

2。Be familiar with the nature. Know what kind of relationship can lead to what conclusions.

3。Knowing what the topic wants you to prove, what you only need to prove this conclusion, little by little to push it to the known conditions.

4。I really can't think of it, try the counter-evidence method, and push the contradictions.

5。Always look at other people's problem-solving ideas, and the problem-solving methods should not be limited, but should be broad.

6。That's what I did, it's been more than 1 month since the start of school, I've taken the exam many times, and I haven't dropped 140.

7。Yes, no, the most important thing is to understand the idea, and after understanding it, I will redo it myself after a while, and if I make it, I will basically have this kind of question.

8。No, come and ask me. I'm very happy to be with you**, I'm also a sophomore in high school this year.

Usually math is still one hundred and two scattered.,It means that your math is not bad.,You can search the Internet for some bullish things (learning),It seems to be a very striking kind.,And then it's gone.。。。 Slowly cultivate)

The ability already exists, and if you use it more, you will ...

Practice more (advice).

that‘s all, thank you!
