How to write high school math well, and how to learn high school math? The more you write, the bette

1. Topic: Accurate, concise, eye-catching and novel.

2. Table of contents: The table of contents is a brief table of the main paragraphs in **. (Short ** does not need to be listed).

4. Keywords or subject words: Keywords are selected from the title, summary and body of **, and are words with substantive significance for the central content of **. Keywords are words that are used as the organic system to index the characteristics of the content, which is convenient for the information system to collect for the reader's search.

Subject headings are normalized words, and when determining subject headings, the subject should be converted into standardized words in the thesaurus according to the indexing and assembly rules.

5. **Text:

1) Introduction: The introduction, also known as the preface, preface and introduction, is used at the beginning of **. The introduction should generally write the author's intention in a general manner, explain the purpose and significance of the topic, and indicate the scope of writing. The introduction should be short and to the point.

a.Presenting - Arguments;

b.analysis of the problem - arguments and arguments;

c.Problem Solving - Arguments and Steps;

d.Conclusion. 6. A ** reference is the main literature that can be referred to or cited in the writing of ** at the end of **. References should be on a separate page, and the annotation method should be in accordance with the "GB7714-87 Post-text Reference Bibliography Rules".

Chinese: Title--Author--Publication Information (Place, Author, Period): Author--Title--Publication Information.

1) The references listed should be official publications for the reader's reference.

High school is mainly about doing questions, huh? Do more questions. And then it's pretty much it.

See the topic clearly! Sort out the knowledge in the book.

Usually do more difficult questions.

It mainly depends on understanding and understanding.

The truth is not what you think, the more you write, the better, everything has to be skillful, with good skills and methods, you will get twice the result with half the effort. Okay, let's stop talking nonsense and get to the point.

First, read the textbook thoroughly, don't rush to do exercises, first study the concepts and even how to arrive at the concepts, as well as theorems, properties, etc., how to deduce, you must study thoroughly.

Second, do the after-class practice of the textbook, don't ignore it because the topic is simple, in fact, no matter how difficult the topic, it is evolved from the simple question, especially pay attention to the summary idea when doing the simple question, in fact, the topic in the textbook is still very valuable, and many classic questions are summarized by the textbook exercises.

Third, according to the teacher's requirements to do exercises, do the questions pay attention to the fine but not in the much, the general teacher is very experienced in teaching, follow the teacher's rhythm to do the question, absolutely yes, do the question in the attention is to establish a wrong question book and a summary of ideas, write down some easy to make mistakes and novel question types, keep flipping, and you will be familiar with it in the future.

Fourth, generally speaking, the amount of questions in the mathematics exam of the first year of high school is not too big and too difficult, if you feel that it is a little short, you need to strengthen the speed, it is recommended that you usually do the problem but entangled in the problem, pinch yourself to do the problem, the speed is also exercised, do the simple and then do the difficult, of course, the mathematics problems of the college entrance examination are still somewhat difficult, how these problems can become simple questions, lies in the first three steps I said, so as to lay a good foundation, of course, the speed must be practiced.

Fifth, specifically emphasize, the problem of the method of doing the problem, do not because you have made a certain topic, you will no longer listen to the teacher explain other methods of solving the problem, you must fully absorb, one is to pay attention to whether there is a simple way, and the other is that once the question type changes, your method may not be applicable and need other methods to do.

Finally, if you are in the third year of high school, find some better college entrance examination review materials to do, and look at it from the beginning when you are done, don't be insatiable, just do it and don't remember it, which is a very serious mistake.

It used to be like this when I was in high school. Because there was a limited amount of time per day at that time. So in order for me to learn better.

I'll do some tests specifically. It's about doing the math you know only once. No, do it a few more times.

And the old stuff is enough to do it once. Because I already will. I won't do it.

So the general teacher lectures. I just won't listen. I won't listen to it if I can.

It works. There are good grades every time.

Listen carefully to the teacher in class and complete homework carefully after class.

(1) a x - 1 0, a x 1 a 0, when 0 a 1, define the domain (-0), and when a 1, define the domain (0,

2) When 0 a 1, y loga(t) is a subtraction function of t and t a x - 1 is a subtraction function of x, so y loga(a x - 1) is incremented on (-0);

When a 1, the same way we get y is incremented on (0.

The solution is shown in the following diagram of the blind spine gripping the seeping god.

Other traces of lead are only like acacia like posture training.

(1) a x - 1 0, a x 1 a 0, when 0 a 1, define the domain (-0), and when a 1, define the domain (0,

2) When 0 a 1, y loga(t) is a subtraction function of t and t a x - 1 is a subtraction function of x, so y loga(a x - 1) is incremented on (-0);

When a 1, the same way we get y is incremented on (0.

1.Because a>0, a=3

t 4 = dry front 6-(-12) = 4, so t = , and because w = 2 t, so w = 2

Bring the points (6,3) and (- 12,0) in, so = 6 so the sock loses y=3sin(2x+6).

2.The ordinate is enlarged by 3 times, the abscissa is reduced by 2 times, and the translation is shifted to the left by 12 units.

y=3sin(2x+π)

Elongated 3 times longitudinally, reduced 2 times transversely, and moved 6 times to the left
