• The typos in Q5 of HW4 have been corrected.
• For the homework idea I give in the tutorial, a feedback note of tutorial 5 is given below. Please fill in the argument RIGOROUSLY after you understand it. other problems can be argued similarly.
• Suggested solution to the tutorial 5 revision exercise would be posted. Frankly, studying solution is not recommended in math study, but we understand that as beginner to write rigorous proof need some reference to start. Please look at it after you have attempted the problems.
• The suggested solution to the tutorial 5 is revised.
• Solution to HW4 is posted.
• Homework 5 has been posted. It is due on Oct 24, Thursday, by 6pm.
• For students from T9 and W2 tutorial session, please be reminded again to fix the typo (a mathematical one) in the tutorial notes printed, the corrected one is uploaded below.
• For tutorial note 6, the parallelogram identity in Q6, please change to 2 * (norm(y) )^2 for the last term, sorry for the typo.
• Homework 6 has been posted. It is due on Oct 31, Thursday, by 6pm. (Remark: The missing matrix entry in Q1(c) is 0, actually you are able to affirm it when you perform the induction.)
• The midterm examination 2 will be held on November 7 (Thurs) from 7:45pm to 9:15pm at LT1, Cheng Yu Tung Building .
• About tutorial 9: For the student in T9 session, please note that there should be some amendment in the question 4 and hint given, because of the inner product convention. A supplementary comment note would be uploaded this afternoon. Please pay attention to it.
• Homework 9 has been posted. It is due on Nov 21, Thursday, by 6pm.
• There would be two extra tutorial session before the final examination, two are of identical content. The schedule are Dec 11 (Wed) : LSB LT5 2:30-430pm, Dec 13 (Fri): LSB LT5 2:30-4:30pm. We will do some basic drill on exam-oriented problems.
• Homework 11 has been posted. It will be due on Dec 6, Friday by 6pm.
• Only the best 8 HWs will be counted for your HW scores.

### Course Description

This is the first part of the Linear Algebra courses. Linear algebra studies vector spaces and the mappings between them. This course is intended to provide conceptual understandings and computational techniques of linear algebra. Topics include: System of linear equations and matrices; vector spaces; linear transformation, determinant and eigenvalues/eigenvectors (if time allows).
