1, with different knowledge contents:

The knowledge content of the same module, version A and version B are different. Some mathematical concepts in version A are less than those in version B, and there are differences between version A and version B in the first chapter. Version A has no inverse trigonometric function and no cotangent value, but version B does.

2, the arrangement order is different:

For example, the principle of ancestral source is mainly studied and explained in the B version of the course. Version A is given in Exploration and Discovery. There is also the third chapter intercept equation, in which version A is given in the example and version B is given in the exercise. There is also the distance between two parallel lines. Version A is given in the exercise and version B appears in the example.

3. The emphasis of difficulty is different:

Compared with version A, version B pays more attention to revealing the essence of concepts and improving mathematical literacy. The A version of Geometry of Space pays attention to the examination of spatial imaginative thinking, and more is to combine practical problems. Version B pays attention to the extension of concepts and cultivates students' ability to analyze problems and think logically.

The method of learning high school mathematics by using extended materials;

1, a lot of basic concepts and basic formulas.

Formulas and concepts are the cornerstones of solving mathematical problems, so remember the concept of formulas first anyway. Secondly, when you know the concept of formula by heart, draw a mind map and make the connection of knowledge clear, so that a main line can be drawn and all branches can be presented!

Find out where you come from.

To solve the problem, we need to know what this problem or this kind of problem is for, what kind of results will be obtained, what conditions are needed, which conditions have been clearly given, which conditions have yet to be deduced, how to consider which implied conditions and so on! If you can't solve it, you should also think about which link has gone wrong. Think like this when you encounter problems, and you will become a habit over time!

3. Learn to ask questions with a purpose, not to do them without a purpose.

In fact, what the sea needs is purposeful training, not aimless problem solving. What is purposeful? As mentioned in the last article, classify the problems, do subtraction, break through one category and solve another!
