Coffee Break

This document is created as a reading material at the time of Mathematics III at Tokyo Tech High School of Science and Technology. We give the uniqueness of the solution is guaranteed when the nonlinear term satisfies a certain condition in the second-order nonlinear ordinary differential equation in this document. We refer to the "SHINSYU KAISEKIGAKU" of Professor Joji Kajiwara (Kyushu University). However, the students told me that it was not a coffee break at all. (This was created with TeX.)
