Yu-Dong Wu, A new proof of a weighted Erd"os-Mordell type inequality,
Forum Geometricorum, 8 (2008) 163--166.

Abstract: 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.
