Development course:
An important concept in the book was first used by British mathematician Hamilton. Although the term vector comes from Hamilton, the idea of vector as a directed line segment has a long history. There are three main lines in the origin and development of vector theory: parallelogram law of velocity and force in physics, position geometry and geometric representation of complex numbers.
The parallelogram concept of velocity and force in physics is one of the important sources of vector theory. /kloc-After the mid-8th century, the work of Euler, Lagrange, Laplace and Cauchy directly led to the establishment of vector mechanics in the mid-9th century. At the same time, the concept of vector is one of the important basic concepts in modern mathematics, which has a profound geometric background. It begins with Leibniz's positional geometry.
Ways to learn mathematics well:
The most important thing in learning mathematics is the ability to solve problems. If you want to do math problems, you must have a lot of practical accumulation and know the steps and methods to solve various problems. If you do more questions, you will feel it. If you come up with similar questions, you will have a solution idea.
The second is to learn to preview. The idea of solving problems is not directly available, nor can it be easily obtained by simply doing a few questions, but accumulated in the preview process. Therefore, preview plays a very important role in the process of mathematics learning. On the one hand, preview can make everyone know something about mathematics in advance, on the other hand, it can cultivate students' autonomous learning ability in mathematics.
You must do more problems when you study mathematics. After understanding the basic definition and knowledge points of mathematics, we need to consolidate our knowledge by doing corresponding exercises. Only by doing more and practicing more can we master what we have learned better. It is easier to look at flowers than embroider when learning mathematics. Only when you really do the problem and experience the actual operation can you learn.
