Sophomore (Grade 11) First Semester Mathematics III Practical Course - Terukokai (Tetsuryokukai) Lecture Text & Exercise Text This text covers a wide range of topics as shown in the table of contents, so it is recommended for those who want to study mathematics with Terukokai materials or are interested in the Terukokai curriculum. I hope that students aiming for the former imperial universities such as Todai and Kyoto University, as well as medical schools, and those who are considering taking the entrance exams will pick this up. The solutions and patterns are all described in the text on the left side of the first photo. The text on the right side contains problems (with answers) for the units corresponding to the text on the left, so I think it's easy to study as a set. There are some writings such as 〇✕ and dates, but it is generally in good condition. The name is written, so it will be cut out. The exercise text has a large number of problems and also includes answers, so I think you can use it just with this.
