Robert Gardner's Online Real Analysis 1

Online Real Analysis 1
with videos on the Zoom server Dr. Bob's Online University
(Not an actual university)

This website includes links to class notes and supplements (in PDF) used in the teaching of East Tennessee State University's Real Analysis 1 (MATH 5210). Links are also available for video presentations of the notes. The videos have been used as of the teaching of online Real Analysis 1, starting in fall 2020. The material is largely based on H. L. Royden and P.M. Fitzpatrick Real Analysis, 4th Edition, Pearson (2010):

Robert "Dr. Bob" Gardner can be reached by e-mail at: gardnerr@etsu.edu. His office is in Gilbreath Hall, Room 308F on the ETSU campus.

The following notes and supplements are all in PDF. The videos are stream from Zoom and include a synchronized transcript. However, ETSU does not have control of the Zoom site and these videos may be taken down as some point. For versions of these videos in mp4 housed on ETSU's Panopto Host, see "Online Real Analysis 1 with videos on ETSU's Panopto Host" webpage.
