Please
note the following guidelines for the course:
Description:
Prerequisite: Math 511.
Grades: The final grade will be determined by homework (100 points), one
midterm exam (100 pts) and
a final exam (200 points). Not all homework problems will be graded. You will get credit if you turn in the statements of all the homework problems written in the correct order. The Final Exam score will replace the midterm score if the latter is lower than the Final Exam score. All grades will
be posted on
UNM Learn.
Homework: You can work together on the homework, but you do need to write your own solutions in your own words. To help the grader, please write your solutions up neatly and clearly and staple the sheets. Each homework has a total of 20 points. The Extra Problems (if any) are not due. Not all homework problems will be graded.
Missed
Exams: Makeup exams can be
arranged for exams missed with a VALID excuse (illness, family emergency,
active participation in scholarly or athletic activities), and ONLY if prior
notice is given.
Disability
Statement:
We will accommodate students with documented disabilities. During the first two
weeks of the semester, those students should inform the instructor of their
particular needs and they should also contact Accessibility Services in Mesa
Vista Hall, Room 2021, phone 2773506. In addition, they should see CATS
Counseling and Therapy Services;
