The classes will be held on the University City campus.
Class times and place: Tue and Th 11:00–12:15 pm in STC 147.
Tue and Th 3:15 pm or at other times by appointment – email me and we will find a time for us to meet. I will be glad to answer all of your questions about the course material, go over some problems together with you, check your assignment work, review together for an exam, or simply discuss course content you may have questions about.
No textbook required. Handouts with new material and practice problems are available on my website for each topic.
Matlab will be used extensively. All students are also recommended to have a calculator.

Number of credits
Calculus 2 or the permission of instructor.
AttendanceThe class lectures will be delivered on campus (at the times listed above). Recordings of the lectures are available for students who miss some classes. To stay on track, it is highly recommended that students attend the classes and use the recordings just for reference.
Students are responsible for all material covered in class, even if attendance is not checked or assignments collected.
ExamsThere will be three semester exams and a cumulative final exam. No makeup exam will be given unless the excuse for missing the scheduled exam is acceptable to the instructor. Any makeup exam must be taken before the next regularly scheduled exam. No exam grade will be dropped.
Assignments and Projects
There will be three assignments and three Matlab projects during the semester.
There will be no makeup assignments. Assignments or projects turned in after their due date will receive an automatic reduction in grade. No assignment or project grade will be dropped.
The projects will focus on numerical solutions using Matlab and applications. Students will be able to install Matlab on their home computers or to use it from a web browser.
The assignments, projects and exams are typically graded in three days after they are turned in. Special circumstances like snow days, school closing or holidays, may occasionally delay the response time. Barring special circumstances, students’ emails are usually responded to within one working day.
