Compulsory 3 is the simplest, and some schools don't learn it directly. Compulsory 2 is more difficult for people with poor spatial imagination, but if it is a liberal arts, compulsory 2 is the basic question of many college entrance examinations. Compulsory 5 may be the most difficult compulsory course, but as long as the foundation is good, there is no problem.

Which book is the most difficult in high school mathematics?

The textbooks involved in the national volume are not difficult, but it is difficult to use the knowledge in the book to do the questions. The other replied that solid geometry is difficult. Indeed, sometimes it takes inspiration to make auxiliary lines, but when you study space vectors, solid geometry in the college entrance examination is an arithmetic problem.

As far as the college entrance examination is concerned, it is difficult to analyze geometry and derivative, but it is useless to preview this part of knowledge. The college entrance examination and textbooks are not at the same level, although the college entrance examination questions are derived from textbooks. If it is really difficult, I feel that the content of statistics (compulsory plus one or two elective courses) is the most difficult, but the college entrance examination is simple.

What is the most difficult compulsory course of senior high school mathematics in PEP?

1, I think the series is more difficult-compulsory five (the most difficult big problem in general college entrance examination is the series), and then compulsory one function is the most important-(including the trigonometric function of compulsory four)-and it is a little difficult to choose the conic curve of 1- 1-for me, compulsory two geometry is the most difficult to learn. In fact, nothing will be too difficult as long as you do more math.

2. Personally, the order of difficulty is: compulsory 2 solid geometry → compulsory 5 series parts → compulsory 1 function → compulsory 4 trigonometric functions → compulsory 3 program questions.
