Each chapter and section has its own emphasis. From the perspective of college entrance examination, function is undoubtedly the most important. Every chapter is closely related to function, so function is the undisputed focus. Then there is another point that is often overlooked: set. Set was first put in high school because it is very important. This is a change of thinking mode, and every picture in the future can also involve the concept and application of set. Then there are trigonometric functions and series, zero activity. It is considered as two difficult chapters. But the contents of these two parts are very regular. As long as the rules are mastered, most problems will be solved. With regard to vectors, some textbooks are vector versions of solid geometry, while others are conventional methods. I don't know which part the landlord belongs to Vector is a simple chapter, but it is a new way of thinking, and it will take some time to accept this way of thinking.

The above is the main content of senior one mathematics, and each chapter should not be underestimated. Some are the key points of the college entrance examination, and some are the chapters that lay the foundation for the later chapters. I won't say much about the content of senior two and senior three, because as long as senior one learns mathematics well and lays a good foundation, senior one mathematics is actually not difficult.

The difficulty of high school mathematics is the way of thinking and method.
