Engineering Mathematics Question

tanpantheon1 SG

This is a question that appeared in my mid-semester test and I would like someone to explain it to me. Thanks in advance.

Given that the matrices A, B and X are m x m order and (I_m) is the identity matrix.

Solve for matrix X, the equation:

AX - BA = (I_m)

Edit: Matrix A, B and X are of m x m order

Hello

It has been some time since I did engineering maths, I am quite rusty.

tanpantheon1 SG

None of the matrices are given

It is given to me that they are of m x m order but they are not given,

Yes this is a very general question but it is in my Mid Sem exam in EEE diploma

And thank you so much !

That was the solution that I was looking for !

No problem

I guess the question wants to test the student's knowledge on manipulating matrix equations, and wants the students to know that a matrix cannot be "divided", and have to use the inverse property.

I have added in some more details and fit the document into a single page pdf file and it can be downloaded here

In case you specialise in power Engineering in SP EEE, I wrote a solution for one of the past year questions recently.

Verify with your lecturer on the accuracy of my solutions, hopefully my approach fits his requirements.

I also believe that this task is aimed at testing knowledge on the manipulation of matrix equations. To solve matrix, I sometimes use the Wolfram Alpha application or website https://assignment.essayshark.com/math-help.html to get a more detailed explanation of a particular action in a real example, or just check the validity of my solutions.

Interesting kind of solution...

请问你为什么不要问你学校的老师，反而问这里的人如何解答你所面对的难题？老师是教你那些知识的人，所以他最有资格帮助你解答难题，然而这里的人懂什么？这里的人都是临时找答案帮你解答难题的，所以他们给的答案即使正确也未必是最好的方案。最好还是问学校的老师比较好，因为他们怎么说是教你那些知识的人，而制作考试题目和改考卷的人也是他们。

如果遇到难题，就问学校老师吧。That’s what the tutorial session is for. Before the tutorial session, do the tutorial questions. Then as and when you encounter difficulty when doing the questions, you make a mark on those questions and ask your lecturer for help during the tutorial session.
