Two: There are some examples in the book to teach you how to solve problems.
Three: the function is not difficult. The most important thing is to keep in mind and think of some properties when doing the problem.
Four: Solid geometry should be imaginative. There is no shortcut in this area. Do more questions. The most important thing is to look at the picture and how to add lines.
Five: the series requires a little ability, and you may be a little tired at first. Again, there are several formulas to remember in the series, so don't recite them wrong.
Six: probability, permutation and combination is to send sub-questions, which is not difficult. It would be better if the teacher gave classic examples in class. There is nothing in this book. Do more questions and just know a few questions.
In fact, the most useful thing in the book is nothing, that is, memorizing the formulas in the book.
Tell you, the college entrance examination paper teacher brought a math book without anything, so all the questions came from the book, and all the knowledge points in the book were mastered. Just do some questions and contact some questions and problem-solving methods.
