Suggested resources
- Speaking mathematics. Examples of how to say formulas out loud. Especially helpful if English is not your first language.
- There is no physical textbook, but we will mostly follow chapters from Paul's Online Notes, which cover several courses from Lamar University.
- Suggested video series. (I have only watched some of these, but I have heard from previous students that they can be helpful.)
