High School Math Learning Methods:

1. Proficient in textbook knowledge.

For example, in the first year of high school, you must learn the formula derivation of trigonometric functions, and the calculation of the length of line segments in solid geometry in the second year of high school, all of which need to be deduced through complex derivation. If you don't have a good grasp of textbook knowledge, you can't do it if you just memorize the formulas, apply the formulas, and change the questions slightly. The fundamental reason is that the knowledge points of the textbook are not thoroughly mastered.

To master the knowledge of the textbook, you must preview the knowledge of the textbook, listen carefully to the teacher's explanation of the textbook knowledge in class, you must ask if you don't understand, review after class, you must review, if you don't understand the spinal circle after the review, it means that you don't understand the class. We must understand what we don't understand in a timely manner.

2. Think more with your brain.

When preparing knowledge before class, you must use your brain to think about the knowledge in the textbook and understand the definitions and theorems in the textbook. If you can't do it, don't read the textbook, think by yourself, only think with your own brain, it is the most valuable.

When you encounter something you don't understand, don't always think about asking, but think about it first. To do the question, don't look at the answer directly, use your brain to think, if you really can't think of it, just look at the answer, or ask the teacher to solve the problem.

3. Do more math exercises.

Some students just read books, and they have a good grasp of textbook knowledge, and they can draw inferences from the content of books, which is very good, but there is still a gap between mastering knowledge and getting high scores. The content of the textbook is a general knowledge, not comprehensive enough, and mastering the knowledge of the textbook can help solve difficult problems, but it does not mean that you can solve difficult problems.

As a high school student, you should buy extracurricular practice books, either pure problem-solving reference books or reference books with both practice questions and detailed solutions. The syllabus is in the textbook, but the exam questions can be varied. Through practice, Zhou Kai should increase his understanding of the knowledge points of the textbook and know the knowledge points more comprehensively by doing questions.

The special values to remember in high school math are as follows:

1. The stuffy family belongs to the symbol, which represents a subordinate relationship between the elements and the set.

2. Finding the product symbol.

3. Summation symbol.

4. It is equivalent to a division sign.

5. The arithmetic square root, if the square of 2 is 4, then the arithmetic square root of 4 is 2.

6. Proportional to, common in physics, such as a b indicates that when a increases, b also increases.

There are six kinds of commonly used symbols in high school mathematics, and the specific writing and meaning are as follows:

1. Geometric symbols.

Geometry is the study of the structure and properties of space. It is one of the most basic research contents in mathematics, and common theorems include the Pythagorean theorem, Euclidean Shenla's theorem, Stewart's theorem, etc.

Common symbols are: (perpendicular), parallel), angle), arc), circle).

2. Algebraic notation.

The object of study of algebra is not only numbers, but various abstract structures. In it we are concerned only with the relations and their nature, and not with the question of what is the number itself.

Commonly used symbols are: (proportional), logical and), logical or), integral), not equal), less than or equal to), greater than or equal to), approximately equal to), infinite).

3. Operator symbols:

The operation symbol is the symbol used in the calculation of mathematics, and the calculation symbol includes plus sign, minus sign, multiplication sign, and division sign.

Common symbols are: (multiplication), division, root sign), addition and subtraction).

4. Set symbols.

A collection is a collective of concrete or abstract objects with a specific nature, which are called elements of the collection. A certain range, a definite, and distinguishable thing, when viewed as a whole, is called a set, or set for short.

Commonly used symbols are: (and), intersection, belonging).

5. Special symbols.

A particular symbol is often used in mathematics to represent an element.

Commonly used symbols are: (sum), pi).

6. Greek symbols:

In mathematics, Greek letters are often used to denote constants, special functions, and some specific variables. In the field of mathematics, it is common for uppercase and lowercase Greek letters to have different meanings and are not related to each other.

Common symbols are: Alpha), Beta), Gamma), Delta), Epsilon), Zeta), Ehta), Sita), Iota), Kampa), Ramda), Fallacy), Paradox).

1. Open any Word document or WPS directly on the computer.

2. In the open document, in the column at the top of the page, click Insert.

3. Select the symbol in the inserted menu column.

4. In the pop-up window, select the symbol you need, if not, you can select other symbols.

5. In the window that slides out, you can select the symbol you need.
