A math textbook for learning about the positional relationships and equations of circles. There is some writing in it, but very little. Also, there are notes on important points the teacher emphasized, which may be helpful for test preparation. I hope that those who want to prepare for Math II or are working hard for entrance exams will find it useful. It has examples, basic problems, and end-of-chapter problems, making it easy to study. - Title: High School Math II - Publisher: Kenkyusha Publishing - Contents: A textbook for learning the basics of math, such as the positional relationships of circles and the equations of circles.
