Syllabus for Sections 901 and OL1:

All times mentioned are in Eastern Time. If you are not in the United States during the semester please be aware that not all countries change to Daylight Saving Time on the same date.
The lectures will be delivered real time online through Zoom at the regular time Section 901 meets (MWF 8.30-9.20). Even if you are enrolled in the asynchronous section, you should feel free to join the real time lecture if you wish. At any time you can stop me and ask a question. The lectures will also be recorded and uploaded to Brightspace. To the best of my knowledge, Zoom does not offer an option to not record all participants’ voices, so if you ask a question your voice will be recorded.
Similarly, office hours will be on Zoom. Those will not be recorded.
Having your camera on during class is not required, but you should feel free to have it on if you like. Students will be muted upon entry to avoid noises, but you can unmute yourself and ask a question at any time.
Bringing pets to class and office hours is encouraged.The MA 266 Course website:
You can communicate with your classmates (and me) on Piazza and form study groups:
The lecture videos can be found in the Kaltura Media Gallery on Brightspace (please note: Google Chrome is recommended for accessing the Gallery):

There will be online and written homework due once a week, usually but not always on Tuesdays. You can collaborate with classmates on homework, but everyone must submit their own solutions, in their own words. The list of assignments can be found below:
https://www.math.purdue.edu/academic/files/courses/2021spring/MA26600/MA266-S21-assignment.pdf
The Online Homework is collected through MyLab Math, in Brightspace. No extensions will be given for online homework.

The written homework will be collected and graded through Gradescope. Your responses can either be handwritten or typed with LaTeX. To receive credit for the written homework you must submit full solutions; you will not receive credit for submitting only the final answer to the problems. See the syllabus for the extensions policy.

[The information below was last updated on of 04/25/2021 to reflect an update in the course-wide ground rules]
Instead of midterms there will be 6 Quizzes throughout the semester. They will typically consist of 1-2 multiple choice and a free response question. The dates are shown below. More information on the logistics will follow soon.
As per the updated course-wide ground rules, quizzes will be unproctored, and they will be open book/notes/internet. You can use calculators or software such as Mathematica, Matlab, Wolfram Alpha etc. You are not allowed to collaborate, share/post online the exam questions, or use external help by classmates or third parties; this includes, but is not limited to, online resources such as Chegg, GroupMe and StackExchange, which are strictly forbidden. The work you submit must reflect your own understanding of the material. Each quiz will be available for a 24-hour window.
The final exam is comprehensive and closed book.
The Sync Online Section 901 will take the final exam in person.
The Async Online Section OL1 will take the final exam online, on MyLab Math. The proctoring software Respondus with Pearson Lockdown Browser will be used. You will need access to a computer with a web camera running Windows or Mac OS for the final exam.
If you have a compelling, documented, and legitimate reason to miss a quiz please inform the instructor as soon as possible.
