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 3D-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.
Grading Policy
Homework is worth 25% of the final 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 extreme, 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.

Overall grade: a perfect score in all tests and homeworks results in a overall grade of 105% .
If your overall score is less than 60% you will receive an F grade, in between 60-69% you will receive a D grade,
in between 70-79% you will receive a C grade, in between 80-89% you will receive a B grade, in between 90-99% you will receive an A grade, with 100% or more you will receive A+.
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.
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 in managing their schedule. This course moves very fast. If you fall behind, even by one section, you may not be able to catch up, since each section generally depends very heavily on the ones before.
A student enrolled in this class has to be capable to read and understand the textbook. If in the past you struggled in self-lecturing mathematics, then this is not the class for you and it is highly recommended you switch to a face-to-face class. The instructor expects for the student to read each section of the textbook, watch the videos and read the class-notes available on the class websiete before attempting to solve the homework problems.
When asking for help you need to show all your work, by typing it on the email (better) or by attaching a weblink to a scanned copy of your work. When asking for help for a WebWork problem it is recommended you use the button email to the instructor at the bottom of the screen, otherwise you may not get any answer.
