Guttman’s Precalculus course utilizes the following OER textbook by David Lippman and Melonie Rasmussen.
I created a series of video lectures for Precalculus in order to provide students with the entire course remotely. These have been used to teach online sections of the course as well as to supplement in-person instruction.
Two of the amplify activities listed under College Algebra and Trigonometry are also useful for Precalculus students.
