In the fall of 2020, I teach MAP2302-5603(16342) – Elementary Differential Equations (syllabus) and and MHF4203-0123,1958(26557,26558) – Foundations of Mathematics (syllabus). The webpages of these courses are on Canvas and there will be no updates for them here. Both are 100% online and take place mostly via Zoom videoconferences with links found on their Canvas webpages. My office hours are MWF 3rd period, 9:35–10:25am at this zoom address.
