Here are my office hours for finals week this semester. If you'd like to see me but can't make these times, please ask for an appointment.

Wed Apr 24, 1:15-2:15pm
Thu Apr 25, 10:00-11:00am, 2:00-4:00pm
Fri Apr 26, 9:00-10:00am, 1:00-4:00pm
Mon Apr 29, 9:00-10:00am, 1:00-2:30pm
Tues Apr 30, 9:00-10:00am
Either online access to Calculus, Early Transcendentals James Stewart, 8th ed. at Cengage.com
Or Calculus, Early Transcendentals James Stewart, 8th ed., There are no other required materials for this course.
If you use the text only as source of exam problems, you're cheating yourself. Read it, and as you do, follow along with the author with paper and pencil.
It would be best for you to have your copy of the textbook by the first day of class, but everyone will have free online access to our book for the first two weeks of class through WebAssign. Students who purchase WebAssign will have online access to our book all semester.
If it becomes necessary for me to change any part of this syllabus, you'll always find its most current version at https://kunklet.people.cofc.edu/ Look for the last change date at the top of this document, and the description of changes at the bottom.
MATH 220 or HONS 215
Have a question and can't reach me for help? Free tutors are available at the CofC Math Lab.
Note: The number of exams and quizzes, their dates and their point values may change in the event of an emergency, e.g., the college changing its schedule or delivery of classes during the semester due to weather or contagion.
We'll have four (4) 75-minute midterm exams, a 2-hour final exam, and weekly quizzes. All exams will be in-person and closed-book: no notes, books, calculators, electronic devices, etc.
Although basic ideas we learn in this course can appear on multiple exams or quizzes, each weekly quiz will be based primarily on material covered since the time of the previous exam or quiz, and, each midterm exam will be based primarily on material covered since the previous midterm. Our final exam will be weighted slightly toward material covered after the last midterm but will otherwise be cumulative. Unless I tell you otherwise, you should assume that any topic of this course could appear on the final. When in doubt, please ask me.
Each of the midterm exams is worth 100 points, the final exam is worth 160 points, and the weekly in-class quizzes are worth 50 points altogether. Minimum required scores for letters grades are
A (90%)
A- (87%)
B+ (83%)
B (80%)
B- (77%)
C+ (73%)
C (70%)
C- (67%)
D+ (63%)
D (60%)
D- (57%)
I won't drop any exams, but if you do better on the final exam than on your worst midterm exam (excluding any on which you received a grade reduction for an honor code violation), I'll raise that (one) midterm exam score by averaging it with your final exam (percentage) score. Then, at the end of the semester, I'll calculate your course grade two ways--based on the percent you earned of the 560 possible exam points, and again based on the percent you earned of the 610 possible exam and quiz points--and give you whichever letter grade comes out higher.
Here are the exams and solutions from the last time I taught this class under a format similar to this semester's. Since course content, exam dates, and the order of topics can change from one semester to the next, these exams might not always cover the material you should be studying for your exams. You can see exactly which sections are represented on these old exams by searching in the solutions for the word "Source."
Calculators will be excluded from all exams and quizzes but will be useful in some of the exercises. For those times when you want a grapher, Desmos.com works great; its 3D grapher (still in beta version) can be found at www.desmos.com/3d. When you want a symbolic calculator, WolphramAlpha.com does everything. Caution: Overreliance on tools such as these will leave you unprepared for the exams.
I strongly encourage you all to attend class every day. Good attendance is a necessary first step towards a good grade. If you're absent on a non-exam day, I'll assume that you have a good reason for missing and will not require an excuse; however, I am unable to reteach the class to everyone who misses a day. Instead, I encourage you to catch up using the text, the videos and notes I've prepared for you, and notes from a classmate, if possible. Try homework for the day you miss, and then bring questions to me in my office. See Make-up Policy for absences on exam days.
Only students officially registered (graded or auditing) for this course may attend class. During the week following the drop/add deadline, the professor will verify student enrollments in this course. Any student appearing on the class roll but determined not to have attended the class even once will be removed, except for cases where a student is absent because of quarantine or isolation due to COVID-19
Exams:
If you must miss an exam, I expect you to make every effort to contact me as soon as possible. Do not delay. Out of fairness to your classmates, I can allow you a make-up exam only if I determine that your absence at exam time and every reasonable time until the make-up is excusable. If you've never seen a doctor for an illness causing you to miss the exam, it might be difficult for me to allow you a makeup. An unexcused exam will be given the grade zero, probably causing you to fail the course.
Quizzes:
At the end of the semester---starting from the date of the last in-class quiz and ending on the last day of final exams---I'll allow you to make up at most two (2) quizzes that you've missed for any reason. These makeups can only be used to replace quizzes that you've missed due to absences, not simply low scores. The topic of the makeup quizzes can be from anything we've covered during this semester and will be taken outside of class at a mutually convenient time. I'll drop your two (2) lowest quiz scores (after any makeups) before computing your quiz average.
Attend every class, practice lots of homework, and read the book!
After each class, do as many of the assigned problems as possible. There will be a short time to ask questions about these at the beginning of the next class. If you run into dificulty, really try; don't flit from one unsolved problem to the next.
Don't just do the homework until you get the right answer, but practice homework problems until you can work through them reliably on an exam. Practice reading the instructions on homework problems. If you are able to do the homework only after looking at some answers in the back to figure out what the question is asking, then you're not prepared for the exams.
Begin extra studying at least a week in advance for the tests. Rework old problems that could appear on the test. Write and rewrite a special set of notes that summarize in your own words the important facts for the test. Include in these notes the different types of problems appearing in the homework and the steps you follow to solve each type. For example, here are the notes written by an A student while studying for the first test in MATH 111 Precalculus.
Here are some review notes I wrote to help you study for the exams. The first pages of these include a review of basic trigonometry, differentiation, and integration. I go over these notes in the videos found here. These notes aren't meant to take the place of the text and lectures.
All class announcements, your exam and quiz grades, and any course materials not found on the syllabus and will be available on Oaks, the College's learning management system. For technical problems with Oaks, please contact the IT Help Desk at 843.953.5457 or studentcomputingsuport@cofc.edu.
Cengage WebAssign is a platform that gives you online access to the textbook and much of the homework. For those who prefer it, I've put together optional WebAssign problem sets that match as much as possible the Assigned Problems listed on this syllabus. These optional problem sets will not be used in the calculation of your grade. These WebAssignments will not be poasted on Oaks; to see them, you must log on to WebAssign.
To set up your account, go to http://www.webassign.net, click on "Enter Class Key" (or "Students/I Have a Class Key"), and then enter our class key:

You'll have free access to WebAssign for the first two weeks of the semester, starting from the first day of class. You'll need a WebAssign access code if you want to use the system after that. Contact WebAssign student support for help using or purchasing WebAssign.

This is a list of all the problems worth doing in each section we'll cover. I won't collect these, but you should be doing them daily.

"5-25" means at least the odd numbered >roblems between 5 and 25, inclusive, and preferably the even numbered problems as well.
* indicates a challenging but worthwhile problem.
** indicates a very challenging problem for your enjoyment only. I won't put a ** problem on an exam, and I probably won't have time to do one in class.
"12.rev" refers to the review exercises at the end of Chapter 12.
[17] means to do problem 17 if time allows us to cover this topic in class. Ask me if you're not sure.
It is impossible to pass this course without good skills from Calculus I. Do the problems marked review in Chapter 3 to review differentiation. Do the problems marked review in Chapter 5 to review the Fundamental Theorem and substitution. Do the problems marked review in Appendix D to review trigonometry.

The Center for Disability Services/SNAP is committed to assisting qualified students with disabilities achieve their academic goals by providing reasonable academic accommodations under appropriate circumstances. If you have a disability and anticipate the need for an accommodation in order to participate in this class, please connect with the Center for Disability Services/SNAP. They will assist you in getting the resources you may need to participate fully in this class. You can contact the Center for Disability Services/SNAP office at 843.953.1431 or at snap@cofc.edu. You can find additional information and request academic accommodations at the Center for Disability Services/SNAP website. Currently, SNAP requires students to schedule alternate testing arrangements at least one week before the exam date.
MATH 221 is an introduction to multivariable calculus. We'll cover the calculus of geometry and motion in three-space, continuity and differentiability of functions of several variables, line integrals and multiple integrals, the theorems of Green and Stokes, and the Divergence Theorem.
By the end of the course, students will be able to
  1. Identify, sketch and parametrize surfaces and space curves. Identify and plot vector fields.
  2. Algebraically manipulate vectors using the dot product, scalar product and cross product to answer geometric questions.
  3. Apply differentiation and integration to parametrized curves to draw conclusions about the geometry of the curve or about the trajectory of a particle.
  4. Compute, interpret, and apply various kinds of derivatives of multi-variable functions (whether scalar functions or vector functions).
  5. Solve multi-variable optimization problems, both constrained and unconstrained.
  6. Set up, evaluate, and apply integrals over two or three dimensional regions, using various coordinate systems and various orders of integration.
  7. Convert multiple integrals between different orders of integration and/or different coordinate systems.
  8. Evaluate and apply line integrals and surface integrals of both scalar functions and vector fields.
  9. Evaluate integrals by selecting an appropriate version of the Fundamental Theorem of Calculus (FTC for Vector Fields, Green's Theorem, Stokes' Theorem, or the Divergence Theorem) to transform the integral into an easier one with a domain of integration having a different dimension.
This course can be used to satisfy some requirements of the undergraduate mathematics degree program, for which there are also some standard goals; students will:
  1. use algebra, geometry, calculus and other track-appropriate sub-disciplines of mathematics to model phenomena in mathematical terms;
  2. use algebra, geometry, calculus and other track-appropriate sub-disciplines of mathematics to derive correct answers to challenging questions by applying the models from the previous Learning Outcome; and
  3. write complete, grammatically and logically correct arguments to prove their conclusions.
These outcomes will be assessed on the final exam.
