About Senior One Mathematics Chapter 1, Senior One Mathematics Chapter 1

My method at that time was to read more textbooks and reference book example questions, read the solutions in the books, and then do more questions, and during the period, I also read more theories in the textbooks, and the textbooks were the most fundamental. In addition, the teacher's exercise class must pay attention to listen and take good notes. As for the theory class, it is divided, some teachers are reading from the book, so there is no need to listen, and some teachers give some other related things, then they have to listen.

I think it's still necessary to listen.,After class, I want you to find a question about this chapter to practice.,Practice makes perfect.,Do more and you will understand.,It doesn't matter if you don't know how to do it.,You can see the answer analysis and digest it slowly.,The topic should be selected well.,There is about textbook knowledge.,You can find your subject teacher to help you with questions for your situation.,I believe a teacher is happy to help a student who loves mathematics.。

Happy learning.

I think it is necessary to listen carefully in class, on the other hand, you still need to do more questions, because you may not be able to change a problem, if you do more, you will have a number in your heart, which is about the same as which problem solutions. Also, you can prepare a book of mistakes, copy down all the questions you did wrong in your homework and exams, take more notes, and turn through them more often! If you're embarrassed to ask the teacher, you can ask your classmates!

Confidence. Nothing else.

Believe in yourself.

Introduce a learning method, called the circular learning method (learned by listening to physicist Yang Zhenning in a lecture at Ontario University), that is, you don't have to worry about the current problems that have not been clarified, continue to study the content of the next section, after learning all the content of a chapter, learn from the beginning, and you will find that the later knowledge has a lot of inspiration for the previous content learning.

The first chapter of high school is about sets, mainly there are many definitions, and the theorem should be analyzed well. In fact, this chapter is not difficult, the key is that many students do not feel the practical use of set operations, and will feel confused. In fact, when you have learned functions, you will understand the purpose of set operations.

Solution: Since f(2x+1)=x 2-2x, then f(3) is equivalent to f(2x+1=3)=x 2-2x

The solution gives x=1, so f(3)=-1

According to the collective knowledge, clarify a-a-1≠a≠-1

Discussion of the sub-chamber sensitive class.

1° a -a-1 = 1 wild ants.

a=2, a=-1 (rounding).

At this time, a=22° a=1.

a²-a-1=-1

Do not sing the ambush in line with.

In summary, a=2

If the two sets are equal, then there is a=a and b a=a b or a =a b and b a=a b, and a = 1, b = 0, and the substitution calculation has the original formula = 1.
