Course description:


The goal of MATH 109 is to continue the study of calculus on the real line, which you started in Calculus I, with a focus on integration, the basics of differential equations, as well as sequences and series. Calculus is a beautiful and venerable subject, whose main aim is to understand the properties of functions, and how they can be used to describe and predict the behavior of various physical systems. The prominence and importance of such study reaches far beyond the pure mathematical endeavor into numerous applications, among others in engineering, natural sciences, and economics. Students enter MATH 109 from a variety of backgrounds. Regardless of your background coming in, our goal is to help every one of you succeed, and enjoy yourselves as much as possible in the process! However, calculus is often a subtle and challenging subject, and experience has taught us (both as students once ourselves, and as educators) that success in MATH 109 requires a lot of work, many hours of study and problem solving, and your active involvement in learning, both inside and outside the classroom. We have designed our course with the aim of helping you stay constantly involved with the course and the material, and within easy reach of some of your best resources: your instructor, your teaching assistants, and your colleagues! Working (quite hard!) together, you will find that at the end of the semester you have not only learned the basics of the course, but mastered the concepts, their connections, and many of their possible applications!


Grading Policies:

Grades of Homework and exams will be updated in Blackboard.

Homework: 30%

Midterm 1: 15%, Midterm 2: 15%

Final Exam: 40%

Missed exams: There will be no make-ups on exams!! It is allowable for a student to be excused for a missed exam if one has a valid reason (acute illness, accident, or other reason preventing one from attending the exam and beyond the student's control). The instructor will determine whether the excuse is valid of not. Should a student be excused from an exam, the score for that missed exam will be calculated based on the student's performance on all remaining exams. Should a student be excused from a final exam, a suitable makeup period and exam will have to be negotiated between the student and the instructor. All exams that are missed without a valid excuse are given the score of 0.



There are ten homework assignments in total. Homework assignments will be posted on the course website regularly. Check the due dates in the schedule above. You are encouraged to do your homework in groups. You are required, however, to write up your homework on your own. There will be five problems from each homework set to be graded. The grades reflect both your analytical and reasoning skills on the graded problems and the completeness of the entire set. Problems marked with an asterisk are challenging, hence not required (5 graded problems will not include any such). Your TA and I will be more than happy to discuss about those challenging problems.

Homework are due on Tuesday or Thursday in sections. You should always turn in your homework to your officially registered section TA, even if you may attend another TA's section occasionally due to time conflict.

Practice Problems




Students with disabilities

Students with documented disabilities or other special needs who require accommodation must register with Student Disability Services. After that, remind the instructor of the specific needs at two weeks prior to each exam; the instructor must be provided with the official letter stating all the needs from Student Disability Services. For more information: http://web.jhu.edu/disabilities



You are encouraged to register for Pilot. Registration will be open on Thursday, Aug 30, at 5pm. For more information: http://advising.jhu.edu/tutoring-mentoring/peer-led-team-learning-pilot/



Help Room: 213 Kreiger Hall. The hours are 9am - 9pm on Monday through Thursday, and 9am - 5pm on Friday. This free service is a very valuable way to get one-on-one help on the current material of a class from other students outside the course. It is staffed by graduate students and advanced undergraduates.


Make-up exams: There will be no make-ups or alternative exams.
