In the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for studying and studying modern science and technology.
Extended data:
I. Mathematical space
The study of space originates from Euclidean geometry, while trigonometry combines space with numbers, including the famous Pythagorean theorem, trigonometric function and so on. Now the research on space is extended to high-dimensional geometry, non-Euclidean geometry and topology.
Numbers and spaces play an important role in analytic geometry, differential geometry and algebraic geometry. In differential geometry, there are concepts such as fiber bundle and calculation on manifold.
Algebraic geometry has the description of geometric objects such as polynomial equation solution set, which combines the concepts of number and space; There is also the study of topological groups, which combines structure and space. Lie groups are used to study space, structure and change.
Second, mathematical punctuation.
Mathematics is an international discipline, which requires all aspects to be rigorous.
Mathematics in primary schools and above in China can be regarded as scientific and technological literature.
China stipulated that the time limit of literary articles must be ".",and the purpose of using mathematics is to avoid confusion with footnotes. Third, because China has submitted a mathematical research report internationally, others have not adopted it, because it was not used in most foreign countries. ". .
In the proof question, ∫ (because) should be followed by ","∴ (so) should be followed by ".". If a big question has several questions, put ";"after each question. Use "."at the end of the last question, use ";" 123④ etc. Table join, the table after the last serial number ending with ".".
