To find a good book for teaching yourself Precalculus with lesson plans and assignments, you can follow these steps:

1. Start by researching popular and highly recommended Precalculus textbooks. Some popular options include "Precalculus" by James Stewart, "Precalculus" by Michael Sullivan, and "Precalculus: Mathematics for Calculus" by James Stewart and Lothar Redlin.

2. Once you have a list of books, visit online marketplaces like Amazon, Barnes & Noble, or Chegg to check the ratings and reviews of these books. Look for books that have positive reviews, clear explanations, and structured lesson plans with assignments.

3. Take advantage of the "Look Inside" or "Preview" feature available for most books on online marketplaces. This will give you a glimpse of the book's content, allowing you to assess its organization, writing style, and the comprehensiveness of the lessons and assignments.

4. Consider checking online education platforms like Coursera, edX, or Khan Academy. These platforms often offer online courses that come with recommended textbooks or reading materials. You can enroll in a precalculus course and use the accompanying textbook as your primary resource.

Many universities provide lecture notes, practice problems, and assignments as supplementary materials for their Precalculus courses. These resources can be valuable self-study tools.

6. Lastly, consider reaching out to your local library or university library. They may have copies of Precalculus textbooks that you can borrow, allowing you to determine which book aligns best with your learning style and preferences before making a purchase.

By following these steps, you can find a suitable Precalculus textbook with lesson plans and assignments that will help you teach yourself effectively.
