Textbook: Linear Algebra with applications, 9th edition,  by Steven J. Leon.  Publisher: Prentice Hall.  The material to be covered includes chapters 1( Matrices and systems of equations), 2(Determinants), 3(Vector spaces), 4(Linear mappings),
5(Orthogonality, 5.1 to 5.6), 6(Eigenvalues, 6.1, 6.3, 6.4).

Course description and purpose:  This course introduces students to linear algebra, which is the branch of mathematics dealing with techniques for solving linear systems. Many industrial and engineering problems can be reduced to solving
linear systems of equations. This explains why it is important to learn techniques for solving such systems.

Course outcome:  After completing the course,  students should be able to:
                                i) solve linear systems using the Gauss or Gauss-Jordan reduction method,
                               ii) find the determinant,the rank and null space of a matrix, reduce a matrix to its LU form, find the inverse of a matrix
                              iii) prove that a given set endowed with appropriate operations is a vector space, prove that a given set is a vector subspace,prove that a mapping is linear
                              iv) find the kernel and range of a linear mapping; find transition matrices
                              vi) find least squares approximations  of  a set of data
                              vii)  find the eigenvalues and eigenvectors of a matrix, ...

Each Chapter Test A is composed of true/false questions that test your knowledge of the material discussed in the chapter; I urge you to pay a special attention to all of them, and to do all the recommended problems. You may discuss your work with me, the LA or with other classmates.

Early Alerts:  The early alerts system is there to help you succeed in this course by detecting difficulties with the course early on in the semester, so that they can be addressed  with your advisor.  Here is how it works: if you are not performing well in the course or if you are frequently absent, I will inform your advisor so that you will be contacted to discuss either issue.

Recommendations: Begin to do your homework from today, January 7, till the last day of class. Set your goal for the course right from the beginning, and work tirelessly toward it; do not let anyone or anything divert you from your goal. This course involves a lot of proofs, and many students struggle with them.. However, if you put the necessary effort into it, then you'll succeed. Do not fall behind; it might prove very difficult to catch up afterwards. Be sure to attend classes regularly, and to diligently deal with any questions or concerns you might have. Remember that I am here to help you succeed; so do not be shy or afraid to ask questions about a notion that you do not understand; it is absolutely normal to not be able to catch every apple as it falls from the tree, but be sure to pick up those that have escaped your grasp. It is my responsibility to make sure that your questions and concerns are swiftly addressed to your satisfaction. Avoid being a passive learner; I expect you to be active in and outside the classroom by regularly doing the homework as we move along the sections, and by asking questions on concepts or homework problems that you do not understand. To facilitate your progress with problem solving, it would be better to note down the homework problems that you could not solve as well as the reason why (maybe you did it and wanted to check your answer, or you started but could not complete, etc...); that would be very helpful when you raise questions about them. You will  acquire the necessary skills needed to successfully complete  this course by doing your homework. I will do my best to help you, and I expect you to do your best. After a test, be sure to review your corrected copy and go over your mistakes with me, so that you do not make the same mistakes in subsequent exams. Do not wait until the eve of a test or due assignment to try to catch up on everything; it would be too late.
Always do your best. "Never do tomorrow what you can do today. Proscratination is the thief of time''.  Commitment +Effort=Success.


Evaluation:
- Three in-class tests  ( Thursday Feb. 06; Thursday  March 12;  Thursday  April 09)
-Ten  quizzes ( Th Jan. 16,  Th  Jan. 23,  Th  Jan.  30,  Th Feb. 13, Th Feb 20,  Th  March 05, Th March 19,  Th March 26, Th April 02, Th April  16)
- Cumulative Final exam ( Tuesday April 21, 2019, 9:45-11:45AM, same room.) 

The three in-class tests will make up 60% of the final grade while the  ten quizzes will account for 10% of the final grade.  The final exam is cumulative, and will be worth 30%. You will be required to produce a photo ID before taking any of the tests, and before writing the final exam. Arrange to be in the room about ten minutes before the class starts; do not arrive late on a quiz or test day, else you will not be allowed to take the quiz or test, and you'll get a zero.  During an exam, you'll not be allowed to leave the room before you are done. For students who took all the quizzes and tests, we will also use the alternate grading scheme: Term work 50%, and final exam 50%, whichever produces the highest grade. No calculators, or ipods, ipads or pagers or cellphones are allowed during the exams or class time; you are not allowed to use or check these devices during the exam or class time, they must be off.  If you're caught with your phone or smart watch during an exam, it will be considered an act of cheating, and you'll get a zero on that exam. There will be no make-up for missed tests or quizzes. If you miss a test/quiz and you produce a doctor certificate indicating that you were sick and unable to write the test/quiz, then the corresponding grade will be added to the final exam grade, otherwise, a zero will be recorded for any missed test/quiz.

Grading Scale:

00-49      F                      50-64   D                     65-69   C   
70-75     C+                    76-79    B-                   80-84   B
85-89     B+                    90-94   A-                   95-100  A

Academic Misconduct:  FIU is a community dedicated to generating and imparting knowledge through excellent teaching and research, the rigorous and respectful exchange of ideas, and community service. All students should respect the right of others to have an equitable opportunity to learn and honestly demonstrate the quality of their learning. Therefore, all students are expected to adhere to a standard of academic conduct, which demonstrates respect for themselves, their fellow students, and the educational mission of the University. All students are deemed by the University to understand that if they are found responsible for academic misconduct, they will be subject to the Academic Misconduct procedures and sanctions, as outlined in the Student Handbook


Incomplete grades:
    It is extremely difficult to qualify for an incomplete grade. An incomplete grade is not a substitute for a failing grade. In order to be considered for an incomplete grade, the student must have completed at least 70% of the course and must be passing with a grade of C or better.

 Important Dates: 
March 16  is the last date to drop the course with a DR  grade. It is of a great importance that you accurately assess your course performance prior to this date.  The university is closed on Monday  January 20 for MLK Day.
Spring Break: February 24-29, 2020.
