HW #13 problems (PDF - due Sat, Dec 14) Supplement on surface integrals - toolkits for spheres, cylinders, graphs, and any parameterized surface.
There will be no class on Nov 28 due to the Thanksgiving holiday. HW #12 problems (PDF - due no later than Sat, Dec 7, but don’t delay!) Supplement on Conservative Vector Fields and the Fundamental Theorem of Line Integrals For further inquiry: Supplement on Curvilinear Coordinates - Div, Grad, Curl, and the Laplacian Exam #2 (covering topics from Lecture #6 - Lecture #11) will take place during an approximately 25 hour window on Nov 21-22 in Canvas/Proctorio beginning after the regular Thursday night class and ending late Friday. The exam will take approximately 70-75 minutes with additional time for downloading, scanning, uploading, etc. for a total allotted time of 90 minutes. The Proctorio Setup Quiz in Canvas should be done prior to taking the exam to make sure that your Chrome browser is updated and that the Proctorio extension is properly installed. Calculators will be permitted, but no other notes, texts or other aids. Needless to say, you should not discuss any aspects of the exam with anyone else during the exam window. HW #11 problems (PDF - due Sat, Nov 23) Supplement on Conservative Vector Fields and the Fundamental Theorem of Line Integrals Exam #1 (covering topics from Lecture #1 - Lecture #5) will take place in Canvas/Proctorio during a 25 hour window opening after our regular class at 11:00pm on Oct 10 and closing at 11:59pm on Fri, Oct 11. The exam will take approximately 70-75 minutes with additional time for downloading, scanning, uploading, etc. for a total allotted time of 90 minutes. The Proctorio Setup Quiz in Canvas should be done prior to taking the exam to make sure that your Chrome browser is updated and that the Proctorio extension is properly installed.

Math E-21a syllabus - Fall 2024 Printable Math E-21a syllabus (PDF) - Fall 2024 [updated July 22, 2024] Calendar [Topics and homework assignments are posted here.] Note: At a minimum, you should have successfully completed a full year of Calculus prior to taking Multivariable Calculus. Some topics from first-year Calculus (sequences and series, differential equations) are not essential for this Multivariable Calculus course, but you should be comfortable with all facets of differentiation and integration and their applications. This course covers the following topics: Calculus of functions of several variables; vectors and vector-valued functions; parameterized curves and surfaces; vector fields; partial derivatives and gradients; optimization; method of Lagrange multipliers; integration over regions in R2 and R3; integration over curves and surfaces; Green’s Theorem, Stokes’ Theorem, Divergence Theorem. Please take note that the pace of this course is quite fast and you will be required to do a substantial amount of homework. You should plan accordingly. Course Meeting Times: All lectures will be recorded and available via the Canvas site for the course. Additional Recitations/Office Hours may be scheduled based on demand.
Textbook: Multivariable Calculus: Concepts and Contexts by James Stewart - either the 4th Edition (published 2010 by Brooks-Cole, ISBN: 0495560545) OR the 3rd Edition (published 2005 by Brooks-Cole, ISBN: 0534410049). The text should be available at The Coop or via the Internet. Note: If you can find an inexpensive copy of the 2nd Edition of the Stewart text or a comparable text, this should also work fine. Each homework assignment will be posted as a PDF for those with other editions of the text. Click on the image of your choice of textbook (to the left) for the best online deals.

Questions, questions, questions..... and some answers 1) Assignments are initially posted on the working course website: http://math.rwinters.com/E21a/ 2) All of the lectures will be live-streamed and recorded and made available within one day but generally sooner. All of the lectures will be available via a link on the course's Canvas Site for the duration of the course and for a few weeks thereafter. 3) The main materials of the course are the lectures, the weekly Lecture Notes, the Stewart text (best to get an inexpensive one online - links for best deals on the course website), and, of course, the homework assignments. 4) All students will be required to submit HW as a single scanned PDF (easily readable and with a reasonable file size, i.e. not scanned at an unnecessarily high resolution). Classes are on Thursday and the recorded lectures are available no later than Friday. HW assignments are usually due no later than the following Saturday night (approx. 9 days later). 5) We will have two midterm exams and a final exam. The Calendar is given at: http://math.rwinters.com/E21a/calendar.htm. Additional details will follow at a later date. Students can find more information at the Extension School website here: https://www.extension.harvard.edu/exams-online-courses 6) There is an optional Math Placement Test to see for yourself if you're ready for the course. It is not required for registration. There is also a Math Question Center online and in Sever Hall, available to students in a range of math classes. 7) The “Graduate” credit option is primarily for students enrolled in certain Extension School graduate programs such as the “Math for Teaching” program. All other students (including high school students) should register for the “Undergraduate” option or the “Noncredit” option (if you will not be submitting homework or taking exams).
Regarding Homework: Your worked solutions should be submitted online via the Canvas site as scanned PDF files. A basic standard is that you don't need to scan at resolution greater than about 120dpi. Anything beyond that is not necessary for handwritten work and significantly increases file size. Black & White scans are preferred unless there is a good reason to scan using color. Please also make sure that the contrast is adjusted properly so that all work is legible. We will select a subset of each assignment for grading. Solutions to all problems will be posted after the deadline. Note: Starting with HW #2, there will be a zero tolerance policy for late HW (unless justified by personal or medical reasons). If you cannot submit HW in class you should scan and submit it no later than Saturday at midnight (Eastern time). You are advised not to wait until midnight just in case you have scanning troubles or other computer troubles. Staying current with the assigned HW is strongly advised.
Your lowest HW score will be dropped when determining course grades. Note: The “Graduate” credit option is primarily for students enrolled in certain Extension School graduate programs such as the “Math for Teaching” program. All other students (including high school students) should register for the “Undergraduate” option or the “Noncredit” option (if you will not be submitting homework or taking exams).
