At present, mathematics education generally imitates the way and difficulty of Olympic Mathematics, which lacks practicality and creates little academic value. It is important to do more exercises and accumulate problem-solving skills. In the process of learning advanced mathematics, it is extremely normal to encounter things that you don't understand. At this time, what you need is to look up some basic elementary mathematics knowledge (pay attention to systematic mastery) and go back to your own research.
College advanced mathematics is a subject that every college student should master, whether it is a science student or a liberal arts student. Because mathematics is an ancient and very important natural subject. Advanced mathematics, based on elementary mathematics, is rigorous in structure and requires students' logical thinking and operational ability.
It is the foundation of various science and engineering disciplines. Learning mathematics well lays a solid foundation for the study of other subjects. Advanced mathematics is a good tool to solve other related problems, in which function limit and calculus are the important parts and core of learning.
Advanced mathematics is an important basic subject in universities. As a science, advanced mathematics has its inherent characteristics. This is a highly abstract, logical and widely used problem. Abstraction is the most basic and remarkable feature of mathematics. Only a high degree of abstraction and unity can profoundly reveal its essential laws.
