The discussion highlights concerns about a book lacking answers to its problems, making it challenging for self-studying students. The absence of a solution manual or numerical answers limits its usability. Suggestions include finding a similar textbook that provides solutions or approaching the book with a specific method: read, reflect, solve independently, and then verify answers. Verification can involve checking results through alternative methods or substituting back into original equations. Additionally, a "reasonableness check" is recommended to assess the validity of answers. Some participants express intent to use a different resource for problem-solving.
