Professor D's (Debrecht) In Depth View of Math

I focus primarily on courses in the STEM curriculum, in the Calculus sequence. I don't just hit the highlights of a topic; I go deep into the content and work many examples of all types.

Students really struggle with the weird and unusual problems, so I try to cover those, as well as the basic types, of the problems I work in the videos.

Playlists are arranged in topic order for the way I cover them in class. Most of my videos are based on the OpenStax Calculus series, which is a free resource for anyone. However, I have used many other calculus books in my career and incorporate what I've learned into my lecture notes. 

Lecture notes are constantly changing and being updated, but right now, I have lecture notes for Trigonometry, Calculus 1, Calculus 2, and Calculus 3.
