Here you can find my video guides and my PDF guides for different math topics. For video and PDF guides, please go here, and for more information about courses I have taught, as well as information on my current classes, please go here. Please note that this page will be updated on a somewhat irregular basis.
The precalculus videos follow topics similar to those in the OpenStax book found here. For a richer explanation on these topics, please consider reviewing the textbook, and then returning to the videos for another example.
