Numerical methods are techniques to approximate mathematical procedures (example of a mathematical procedure is an integral). Approximations are needed because we either cannot solve the procedure analytically (example is the standard normal cumulative distribution function)
or because the analytical method is intractable (example is solving a set of a thousand simultaneous linear equations for a thousand unknowns for finding forces in a truss).
In this course, you will
· Learn the numerical methods for the following mathematical procedures and topics - Differentiation, Nonlinear Equations, Simultaneous Linear Equations, Interpolation, Regression, Integration, and Ordinary Differential Equations.
· Calculation of errors and their relationship to the accuracy of the numerical solutions is emphasized throughout the course.
· Programming via MATLAB will be used to reinforce the fundamentals of the course as well as to solve intractable/real-life problems.
By the end of the course, the students will be able to

Tests#1, 2, 3: Each test is graded out of 100. Tests are closed book and closed notes. A formula sheet made by the instructor is allowed.
Special Assignments/Computer Project Reports: Computer project reports are due at the beginning of the class period they are due in. If you are not coming to class, you can slip your report/special assignment under my door one hour before the class period begins on the day it is due. If it is slipped after this time, it will not be graded. Late reports are not accepted or graded.
Reports not submitted when they are due will be graded later only if you have a legitimate, verifiable, and documented excuse as given in the syllabus. You need to submit your report/special assignment on the first day you are back in class.
The special assignments will be given throughout the semester. These may include submitting assigned HW problems for a grade, mini-projects, essays, in-class assignments such as minute papers, reflective resubmission of graded quizzes, etc.
Online Quizzes: These are online quizzes that get automatically graded and are taken on CANVAS before and after each lecture.
Final Exam: The final exam includes combination of multiple-choice and free response questions. The final exam is comprehensive examination of all the topics covered in the course.
Concept Test: This is a test of the conceptual knowledge of the course. The test is a multiple choice questions test with anywhere from 16-30 questions asked in a 75-minute test.
Grading Rubric: Each free-response question on test/final exam is graded on a scale of 0-4.
4: Demonstrates complete understanding of the problem. All requirements of the task are included in response.
3: Demonstrates considerable understanding of the problem. All requirements of the task are included.
2: Demonstrates partial understanding of the problem. Most requirements of the task are included.
1: Demonstrates little understanding of the problem. Many requirements of the task are missing. (There is something salvageable.)
0: Left blank or shows no demonstration of understanding of the problem. (Maybe simply repeated the data or copied formulas, or showing formulas that are not even relevant.)
Extra Credit: You can earn two (2) extra credit points applied directly to your overall grade by participating in a research project study funded by the National Science Foundation to enhance the educational experience received by students in the class. More information about this study will be made available on Piazza and Blackboard later during the semester. There is no penalty if you choose not to participate in this study. Alternatively, you can choose to write a 500-word essay on topics of numerical methods that are mutually agreed upon between you and the instructor for the same credit.
Attendance and Late Policy: YOU SHOULD NOT RUSH TO MY CLASS as nothing is that important in life. I myself may get to come late to a class for something that is beyond my control or even with the best of planning. In the last 28 years of teaching, I have been late to class five times.
Curving the Grade: The adjustments made to your course grade is as follows and is made to the tests#1, 2, 3, concept test, and the final examination.
If the average for students registered for the course (all withdrawal students and students missing the exam are not included in the calculation) for any of the tests is less than 70%, the difference is added to every registered student's grade for that test (exception include students missing a test for verifiable excuse, where adjustments are at the discretion of the instructor).
Grade A+ is 98‑100 (4.00) Grade A is 90-97 (4.00) Grade A- is 86-89 (3.67)
Grade B+ is 83-85 (3.33) Grade B is 80-82 (3.00) Grade B- is 76-79 (2.67)
Grade C+ is 73-75 (2.33) Grade C is 70-72 (2.00) Grade C– is 66-69 (1.67)
Grade D+ is 63-65 (1.33) Grade D is 60-62 (1.00) Grade D‑ is 56‑59 (0.67)
Grade F is 0‑55 (0.00).
Your final grade will be calculated as follows at the end of the course. A number 0.999999 will be added to your overall percentage grade. The integer part (INT function in Excel) of the grade will be recorded as your final grade. Course grades will be evaluated on the above given percentages and a letter grade will be assigned to you as outlined in the University catalog for undergraduate students (2015-2016).
Course grades will be evaluated on percentage score and a letter grade will be assigned to you as outlined in the University catalog for undergraduate students (2015-2016).
Do not wait until the last day before an examination or a test to ask questions. Graded assignments and quizzes not picked up when handed out in class can be picked up only during the above given office hours or at the end of the class. Graded assignments and tests not picked up by January 14, 2016 will be discarded. Final exams or concept tests are not returned.
Attendance is not compulsory and you are responsible for topics covered in class, announcements made in class, homework assigned in class, and submitting lab reports and special assignments on time.
Re-grading of a test, lab report, essay or computer project should be requested within five working days of it being returned to you. Re-grading after the final grade is assigned for the course will be allowed only in extreme circumstances. Mistakes in the grade book entries should be rectified as soon as possible to avoid any change of grade issues. You will need a copy of all your graded tests for verification. KEEP ALL YOUR GRADED PAPERS TILL THE FINAL GRADE IS ASSIGNED.
Grades will be updated on https://my.usf.edu.
NO make‑up tests will be given. However, in the event of a serious illness (physician's statement documenting severity of illness required), death in the family or other legitimate, documented, verifiable emergency resulting in the absence from a schedule test, each case will be evaluated separately. The decision of the instructor is final. An example of a make-up score is that if you miss a test, you may be given the same grade as the final exam score in the missed topics, and so on. Curving of make-up grades is discretion of the instructor.
Notification of absence must be given before the commencement of the scheduled examination or test to me. You need to type a professional memo (see sample) about your absence addressed to me as soon as possible. Attach any documentation with it (no e-mails will be accepted).
Do not presume that your reasons for missing an examination or test are acceptable unless authorization is given to you.
Students who need to be absent under this rule must provide written notice of date(s) to me by the second-class meeting. The request needs to be reasonable under university rules.
POLICY ON STUDENT DISABILITY ACCOMMODATIONS
“Students in need of academic accommodations for a disability may consult with the office of Students with Disabilities Services to arrange appropriate accommodations. Students are required to give reasonable notice prior to requesting an accommodation.” The website is http://www.sds.usf.edu/index.htm.
If you are found cheating on any of the tests, exams, graded HWs, projects, you will get a 'FF’ for the whole course, and referred to the Dean's office for further process or appeal.
Academic disruption includes excessive side talking, lack of respect for your fellow classmates and the instructor, listening to music, cell phone distractions, solving crossword puzzles. These will be handled as per the undergraduate catalog of 2012-13.
The following restates portions of USF Academic Policy from the USF Undergraduate Manual concerning the “incomplete” grade, academic dishonesty, and disruption of academic process. The faculty of the Department of Mechanical Engineering requests all students in the department to be informed of these policies.
Incomplete Grade Policy
“It may be awarded to an undergraduate student only when a small portion of the students work is incomplete and only when the student is otherwise earning a passing grade.”
“Each individual is expected to earn his/her degree on the basis of personal effort. Consequently, any form of cheating on examinations or plagiarism on assigned papers constitutes unacceptable deceit and dishonesty.”
Penalties for Academic Dishonesty
“Penalties for academic dishonesty will depend on the seriousness of the offense and may include assignment of an “F” or a numerical value of zero on the subject paper, lab report, etc., an “F” or an “FF” grade (the latter indicating academic dishonesty) in the course, suspension or expulsion from the University.” In this course, a FF is assigned for any cheating in the assigned HW, quizzes and/or competency tests.
Disruption of Academic Process
“Disruption of the classroom or teaching environment is also unacceptable. This cannot be tolerated in the University community, and will be punishable, according to the seriousness of the offense.”
Punishment Guidelines for Disruption of Academic Process
“Punishment for disruption of academic process will depend on the seriousness of the disruption and will range from a private verbal reprimand to dismissal from class with a final grade of “W,” if the student is passing the course. If the student is not passing, a grade of “F” will be shown on the student record. Particularly serious instances of disruption of the academic process may result in suspension or permanent expulsion from the University.”
All unauthorized recordings of class are prohibited. Recordings that accommodate individual student needs must be approved in advance and may be used for personal use during the semester only; redistribution is strictly prohibited.
In response to student requests and instructor observations, the following class rules will apply in this course:
The purpose of these class rules is to eliminate activity that is disruptive to the academic process. Most students view these as a common courtesy to the instructor and fellow students. Failure to comply with a class rule will be viewed as a Disruption to the Academic Process. The penalty for such disruption is given in the syllabus.
