A very important concept in linear algebra is the vector space r^n, which will focus on a series of properties of vector space.A vector space is a non-empty set v consisting of some vector elements, which needs to satisfy the following axioms:The subspace H of the vector space V needs to meet the following three conditions:The two theorems are in the elaboration of how to form subspace, and its proof simply proves that the constructed subspace satisfi

Chapter 2 determining factors § 1 Introduction Solving equations is a basic problem in algebra. Especially in the algebra learned by Middle School, solving equations plays an important role. This chapter and the next chapter mainly discuss the General Multivariate equations,

In the following chapters, we will discuss some basic knowledge about search engines. To really do a good job in search engines, There is no shortcut. To do a good job of searching, the most basic requirement is to analyze 10-20 bad search results every day, so that you will feel it only after a period of time. However, many engineers often cannot do this. The search diligence principle is actually very simple: automatically download as many web pages as possible, create a fast and effective ind

Technology is divided into two types of surgery, the specific way of doing things is surgery, the principle and principles of doing things are Tao. The principle of search engine is actually very simple, build a search engine roughly need to do such a few things: Automatically download as many pages as possible; Establish a fast and effective index; A fair and accurate sort of page based on relevance.1 Boolean algebra The theory of Yin and yang in anc

, the linear equations (1) can use the following matrix (2) . In fact, with (2), the linear equations except words that represent unknown numbers (1) are determined, and the words used to represent unknown numbers are of course not substantive. I learned how to use addition and subtraction elimination methods and substitution elimination methods to solve binary and ternary linear equations in the Algebra I learned in middle school. in fact, this metho

§ 1 Field The addition, subtraction, multiplication, division, and other operations of numbers are generally called the algebra of numbers. the problem of algebra mainly involves the algebraic nature of numbers. Most of these properties are common to all rational numbers, real numbers, and plural numbers. Definition 1It is a set composed of multiple numbers, including 0
