In the process of a variable (independent variable) changing (limit process), the infinite approximation number of this variable is 0 (limit is 0), which is not "limit of function" (limit of function is constant). Because predecessors gave it an image called infinitesimal. Mathematics is a discipline that studies concepts such as quantity, structure, change and space, and it is the foundation of natural science.
It is also the crystallization of human wisdom. Mathematics is everywhere in our life, from the simplest arithmetic to complex calculus, from basic geometry to high-dimensional space, and its application range is extremely wide. The development of mathematics can be traced back to ancient times. The ancient Egyptians used mathematics to measure land, build pyramids and conduct trade activities.
In the Middle Ages, Arab mathematicians made great contributions to mathematics. They studied algebra and equations and introduced the concept of zero. At the same time, China mathematicians have made outstanding achievements in algebra, geometry and probability theory. Since modern times, mathematics has become one of the basic tools of natural science. The development of calculus has brought revolutionary progress to physics.
Statistics is also widely used in economics, sociology and biology. Mathematics is not only a science, but also a way of thinking and culture. The ideas and methods of mathematics have penetrated into philosophy, literature, art, politics and other fields. It not only helps us to understand and solve practical problems, but also inspires our thoughts and improves our thinking ability and creativity.
Greek mathematicians have a deeper understanding of mathematics and developed some important theories such as Euclid geometry and Archimedes mathematics. In a word, mathematics is an important subject with unique charm and wide application. It is not only one of the important tools for us to know the world, but also an important part of our wisdom and cultural heritage. Let's explore the mystery of mathematics and feel its charm!
