Which part of high school mathematics is the most difficult? How to learn?
In fact, if anything goes wrong, there will be very difficult problems. I didn't know until I went to college that mathematics is not difficult for high school students. Last year's college entrance examination, math 148, worked as a tutor for half a year. I have read all the math problems in basic high school. Different questions have different difficult methods. It is not difficult to summarize 1 briefly. The first chapter, set and simple logic, is too few things. A multiple-choice question (referring to the college entrance examination) only has chapter 12, statistics, which is new. It's just a superficial exam and back expectations. The definition of variance can be used as Chapter 15, Complex Numbers. Because the new textbook has learned vectors, this chapter has become a chicken rib, and it is a choice to cancel it sooner or later. 2. Less difficult: The fourth chapter, trigonometric function, is not easy in itself, and there are many formulas and techniques, but the new outline obviously reduces the requirements of this chapter. Generally, the college entrance examination is the first big question, which belongs to sub-topics. The fifth chapter, vector, is a new content, only testing basic concepts. But this chapter is sometimes written with application questions. It is not difficult in itself, and the problem may be solved later. Chapter 9, solid geometry, needless to say, is similar to a triangle and belongs to the first three parts of the big topic. Chapters 10 and 11 are permutation and combination, binomial theorem, probability, and the following concepts. Chapter 13, limit, is a sub-topic in the big topic; Chapter 14, Derivative, belongs to laying the foundation for advanced mathematics. Because of the lack of strict mathematical foundation, it is just a set of formulas. However, after the provincial proposition, some function questions with high generation background often appear in the finale questions of some provinces, which require higher derivatives. I want to know which province you are from. 3. Chapter II, Functions, and Chapter III, Order. More than 50% of the college entrance examination finale questions are a combination of the two. It is suggested to master the basic concepts when reviewing. Try your best to solve this problem. Chapter VI, Inequality. Generally, it is also combined with functions. Pure inequality problems are not tested now. As for the comprehensive questions, it mainly lies in skills, which has little to do with what is said in this chapter. Chapters 7 and 8, analysis, are also traditional topics. The analysis is difficult and the score rate is low. The problem of function class is mainly thought, and the problem of analytic class lies in its super calculation and observation ability.
