## Course Description

This course covers Calculus of several variables. The concepts are extensions of the concepts from Calculus I. It is necessary to remind the students of those basic concepts, as the course progresses. Multivariable Calculus is an important tool in Science and Engineering. The instructor should emphasize the importance of all relevant concepts, including: curves and surfaces in Euclidean 3-space, length and curvature, area and volume; surfaces, partial derivatives, total differential, tangent planes to surfaces; gradient; vector-valued functions; path integral; Stokes' theorem, which should be stated, with an emphasis on its important particular cases, Green's Theorem and Divergence Theorem - followed by a few basic examples.

Handwritten Notes on Blackboard, worth 10% of the overall grade.
Almost every Sunday, the student must to submit on Blackboard detailed handwritten notes of the selected examples taken from the textbook. For each assignment, the student will receive a Pass/Fail grade, which will build up the 10% of the overall grade. The assignments will be posted on Blackboard ahead of time.

Homework on WebWork, worth 20% of the overall grade.
However in order to pass the class your overall grade in the HW at the end of the semester should be at least 50%. This may appear radical, but besides the exams, the HW system is a major tool the instructor has to asses your class performances. The instructor will check regularly your HW score and let you know if you are not on track.

Examinations:
 Exam #1: Thur, Feb 9 1.5 hour interval of your choice on WebWork worth 15% of the overall grade Exam #2: Thur, Mar 9 1.5 hour interval of your choice on WebWork worth 15% of the overall grade Exam #3: Thur, Apr 13 1.5 hour interval of your choice on WebWork worth 15% of the overall grade Final Exam: Fri, May 5 2.5 hour interval of your choice on WebWork worth 30% of the overall grade

Overall final grade: a perfect score in all the assesments results in a overall grade of 105%.

Exam Policies

Students are expected to take the midterm exams and the final exam as scheduled. There are no make ups for the examinations, except for reasons of illness, stated in writing by a medical doctor, observance of a religious holiday, university justified field trips or work conflicts. Usually, no other reasons are accepted (events, plane tickets, weddings, ...).

See below some general exam information and rules:

1) All exams are taken on the WebWork system. You have a 24-hour window to start your test in the given day. Once started you must complete the test in the given time.
2) Exam 1 covers chapters 9 and 10 (HW01-HW03), Exam 2 covers chapter 11 (HW04-HW06), Exam 3 covers chapter 12 (HW07-HW09), the Final Exam is comprehensive and it covers chapters 9 to 13 (HW01-HW11).
3) In each exam there will be several multiple choice questions.
4) The correct answer is ALWAYS among the 5 choices: I never use the "None of the above" choice.
5) You will have only ONE ATTEMPT to get it right.
6) To submit your work, you need to press the "Grade Test" button at the very bottom of the page . After you press it, you cannot change any of your answers. Be sure to complete all your work before pressing it.
7) The "Grade Test" button should be pressed before the due date otherwise a 0% score will be recorded.
8) The test score and solution keys will be available after 2-3 days
9) If you experience any technical problem during the exam, DO NOT WAIT, but immediately notify me during or after the test. When you notify me, be sure to explain carefully what happened, and be ready to take action. There is no much to do for me if you contact me (OR IF YOU TAKE ACTION) after days have passed.

Class Policies

This is a distance class, all the students enrolled in this class should be highly responsible for managing their schedule. The instructor expects the student to read each book section and watch the short videos below before attempting to solve the homework problems. When asking for help, you need to show your work by typing it on the email (better) or by attaching a scanned copy of your work. When asking for help with a WebWork problem, you should use the button email to the instructor at the bottom of the screen. Otherwise, you may not get any answer.
