What chapters in the fifth edition of Linear Algebra Tongji are not examined? I am a graduate stude

I'll come on, I took the exam this year, and I was also ranked third!

Let's start with the line generation: Chapter 4, Section 5; The entire sixth chapter.

Look at probability: hypothesis testing, regression analysis, analysis of variance and experimental design are not considered; N-dimensional normal random variables are not examined, interval estimation is not examined, that's all!

It is recommended to buy a reference book to compare it at that time. I wish you all the best in the graduate school entrance examination.

Summary: The scanned pdf file of the textbook "Linear Algebra in Engineering Mathematics Sixth Edition" can be purchased by consulting the teacher of the institution, or you can go to Xinhua Bookstore to buy it.

Linear Algebra (Sixth Edition) is a national planning textbook for undergraduate students of general higher education in the Twelfth Five-Year Plan, edited by the Department of Mathematics of Tongji University and published by Higher Education Press, which can be used by various engineering majors in colleges and universities, including emerging engineering majors such as management engineering and biological engineering, and can also be read by self-learners, graduate students and scientific and technological workers.

Introduction:

I am under the sixth edition of Tongji, and I will send it to you together with the solution to the exercises, I hope it will be useful to you.

You have to search for engineering math linear algebra. You have one less search for 'engineering mathematics', and the two books are not the same. Directly give you a **.

This answer is outdated, isn't it, why is it different from what we used this year?

Note b =

a α^t 0

It is known that r(b)=r(a).

And a is an n-order square, so r(a)<=n.

So r(b)=r(a)<=n.

By b is the n+1 phalanx.

Therefore the system of homogeneous linear equations bx = 0 has a non-zero solution.

So (d) correct.

Why not (a), (b).

Obviously there is r(a)<=r(a, )=r(b)=r(a), so r(a)=r(a, ).

Therefore ax= has a solution.

But since it is not clear whether r(a) is less than n [at this time (a) is correct] or equal to n [at this time (b) is correct].

Therefore, (a) and (b) cannot be selected.

Why is it anonymous, the system has to deduct 10 points, it is better to use it as a reward

The fifth edition of this book is based on the fourth edition, with reference to the basic requirements for the teaching of basic mathematics courses for engineering undergraduates (hereinafter referred to as the basic teaching requirements) revised in the fourth edition, and considering the actual situation of current teaching.

The main idea of this revision is to appropriately reduce the requirements of theoretical reasoning and pay attention to the matrix method of solving problems on the premise of meeting the basic requirements of teaching. To this end, in addition to Chapter 6, which is still marked with an *, parts of Chapter 1 and Chapter 5 (e.g

The knowledge of permutations introduced to prove the basic properties of determinants, the knowledge of elementary matrices introduced to prove the basic properties of elementary transformations of matrices, and some theorem proofs) are changed to be typeset in small print to indicate that they are not compulsory reading, so as to facilitate a better grasp of the content prescribed by the basic requirements of teaching in a limited number of hours. These contents, which are typeset in small print or marked with *, have higher requirements for readers to choose from. In addition, appropriate adjustments have been made to the example questions and exercises during the revision.

The revision work is still undertaken by Comrade Luo Chengqin of Tongji University. With the support of the Department of Higher Education of the Ministry of Education and the Higher Education Press, this book is included in the "Tenth Five-Year Plan" national planning textbook for general higher education. At the same time, this book has also been included in the project of "Construction of 100 Excellent Textbooks for Higher Education" of Higher Education Press and the construction plan of textbooks for Tongji University.

I would like to express my heartfelt thanks to the Department of Higher Education of the Ministry of Education, the Higher Education Institute and the relevant departments of Tongji University for their concern and support for this book.

Supplement upstairs 2

This linear transformation is essentially a projection towards the x-axis.

The matrix a, which corresponds to this linear transformation, is the one (1,0;0,0), left by x, is ax=(1,0;0,0)(x1,x2)t = (x1,0)tx=(x1,x2)t, after transformation, only the abscissa remains, and the ordinate is not.

For example, there is a light directly above this point (x1, x2), and the shadow of this point is cast on the x-axis below, and the t behind it represents the row vector transposed into a column vector.

Multiply a*=|a|e

2.I don't understand!!

3.The corresponding element and the algebraic remainder are multiplied by a value, and the other elements and the algebraic remainder are multiplied by 0, so only the last line remains.

Engineering Mathematics - Linear Algebra Tongji Fifth Edition (New Edition) is the fifth edition of Linear Algebra edited by the Department of Mathematics of Tongji University, which is revised according to the basic teaching requirements of linear algebra courses for engineering undergraduates (hereinafter referred to as the basic teaching requirements). The revision refers to the experience and achievements of linear algebra course and textbook construction in recent years, and makes a comprehensive review and modification of the original content, and the leading idea of the revision is: under the premise of meeting the basic requirements of teaching, the requirements of theoretical derivation should be appropriately reduced, and the matrix method of solving problems should be emphasized.

For this reason, the proofs of some of the theories in the book were typeset in small print, and some examples and exercises were adjusted.
