Math 1050 | College Algebra
These lecture videos are organized in an order that corresponds with the book we have used recently for our Math1050 courses. (Precalculus by Larsen, Hostetler; NOTE: what we have labeled as chapter 4, 5 and 6 are chapters 7, 8 and 9 respectively in the book.) We have numbered the videos for quick reference so it's reasonably obvious that each subsequent video presumes knowledge of the previous videos' material. Along with the video lecture for each topic, we have included the "pre-notes" and "post-notes" which are the notes of the lecture before we did the problems and after we worked everything out during the lecture, respectively. You may want to download the notes to use as a reference while watching the lecture video, or for later reference.If you find an error in the lecture or a problem with the video, or if you would like to give feedback to us about these lectures, please email [email protected] to do so.
NOTE: These videos were not recorded in stereo sound. If you are listening to these videos on headphones, you may want to consider setting your sound channels to come through both sides. This document will give you an idea of how to accomplish that.
