1st REVIEW DAY Instructor: Ms. Hoa Nguyen In the Take-home Quiz 16 (Review Sections 10.3 - 10.5) , the questions that most of you have trouble with are Questions 7, 11, 17, 18, 15, 16, 2, 6, 13, 12, 5, 4, 3, 8. For a short way to solve Questions 11, 12, 17 and 18, please look at the online solutions. At least one question similar to Questions 2 or 16 will be given on Test 3. Question 2 asks you to find the REDUCED row echelon form of the matrix. Question 16 requires you to solve for an inverse of the given matrix A (in which you have to find the REDUCED form of the set-up matrix ( A | I )). If you do not how to find the REDUCED form, please look at the online solutions of these two questions. In Questions 15 and 16, after you find the inverse of the given matrix, please multiply the

Unformatted text preview: inverse with the given matrix to see if the result is an identity matrix. Look at the online solutions to see what I mean here. On the Test, solve simple problems ﬁrst, then do the questions with long computations as Questions 2 and 16 last. Next Monday’s Review will be held at the Seminar Room of the School of Computational Science (4th ﬂoor of DIRAC library). For directions, check under “Classroom Changes”, “Days & New Location”. The Review will be organized similarly to the Game Day: questions will be displayed on the screen and student’s names will be called. If you answer the question correctly, I will change your LOWEST Quiz grade to 10. There is no penalty if you miss the question. 1...
