Equation memory device for advanced mathematics and use method thereof

Technical Field

The invention relates to the technical field of teaching devices, in particular to an equation memory device for advanced mathematics and a using method thereof.

Background

Advanced mathematics is generally considered to be a basic subject formed by micro-integration after the 17 th century, deeper algebra, geometry and the cross content between them. Mathematics is more difficult to learn than elementary mathematics and medium mathematics, and belongs to university courses, so the mathematics is often called as high mathematics and the mathematics is often called as calculus in textbooks. Higher mathematics are studied for the variables, and the variables can be studied more than just by higher mathematics. As for courses accompanying "higher mathematics", there are generally: linear algebra, probability theory and mathematical statistics, the elementary mathematics research is constant and uniform variables, and the advanced mathematics research is non-uniform variables. Advanced mathematics is an important basic subject of a science and technology colleges, is a necessary mathematics course for non-mathematics professional science and technology specialty students and is a necessary course for other specialties, and has inherent characteristics as a basic science, namely high abstraction, strict logic and wide application. The abstract and the computability are the most basic and obvious characteristics of mathematics, and have high abstract and unity, so that the essential rules can be deeply disclosed and can be widely applied. Strict logicality means that in the induction and arrangement of mathematical theories, no matter concepts and expressions, judgment and reasoning, logical rules are applied and the thinking rules are followed. Therefore, mathematics is also a thought method, and the process of learning mathematics is the process of thinking training. The progress of human society is not separated from the wide application of mathematics. Especially, in modern times, the application field of mathematics is widened due to the appearance and popularization of electronic computers, modern mathematics is becoming a strong power of scientific and technological development, and meanwhile, the modern mathematics also widely and deeply permeates into the field of social science, and high-level mathematics has a large number of mathematical formulas such as Newton Leimnitz formulas and the like due to higher depth and deeper depth, so that the formulas and the complex memory thereof are troublesome, the understanding difficulty is high, and in the teaching process, some tools are usually assisted to help students to understand the formulas and further memorize the formulas, and the formulas are finally and flexibly used.

However, the conventional equation memory device is a tool for an electronic display screen to mainly assist memory by demonstrating videos, and is very boring, and lacks communication and interestingness, so that a new solution is necessary to be provided.

The prior equation memory device has the defect of lacking interest in the education process, and therefore, the equation memory device for advanced mathematics and the use method thereof are provided.
