The series of Mathematics in Senior High School is divided into 10 volumes: function, trigonometric function, inequality, plane servo, sequence, analytic geometry, solid geometry, permutation, probability statistics, calculus, algorithm and complex number, logical term and solid geometry. Students can choose different volumes according to their own situation to learn and consolidate their professional knowledge. When writing this set of books, we took into account the different needs of students at all stages, learned skills from mathematics teaching in the whole high school stage, and carried out a set of special knowledge. For example, the first 15 class hours of the book "Easy Processing of Mathematics and Functions in Senior High School" should be synchronized with the textbook, which is suitable for senior one students. The last few class hours are the cross-cutting contents of functions and other chapters, and are also suitable for senior two and senior three students. It can be said that such a book integrates all the functions of high school and can help students to eliminate the worries of this section. This is "easy to get high school"
