A new proof of a weighted Erdos-Mordell type inequality - Yu-Dong Wu In this short note, by making use of one of Liu's theorems and Cauchy-Schwarz Inequality, we solve a conjecture posed by Jian Liu and give a new proof of a weighted Erd"os-Mordell type inequality. Some interesting corollaries are also given at the end. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
