  • NEW Homework 2 is posted; due as indicated for each problem.
  • The main communication between the class and me will be through Moodle, since your work will be uploaded there. Once you are logged in https://wolfware.ncsu.edu to see your courses, click on the orange "m" to go to the Moodle boiler plate. (Clicking on the title takes you to this page). Individually, you can email me.
  • I will deliver the lectures live from home using the Zoom client https://ncsu.zoom.us (click Download client at bottom of page) on your device (cell phone, laptop, computer).
    The lectures will start on August 17, 8:30am. I will email a Zoom ID to you at the beginning of the lecture, so that you can join the live meeting via this ID. I will also post the ID in the Moodle Lecture 1 title. The website https://ncsu.zoom.us/j/<ID> where <ID> is the ID may work.
    In addition, I will record the lectures and post links to the recordings on Moodle.
  • I will require attendance for credit. To get credit for each lecture, the only thing you have to do is go to Moodle and mark your attendance ``P'' (present). You have until 11:59pm on each day of each lecture to do so for that lecture.
  • My virtual office hours, to be held via Zoom, are listed on my schedule.
