Abstract | The formula for the shortest distance of a point from a line can be derived in several different ways. Some typical methods are taught at the elementary (i.e., high-school and junior college) level. However, solving such "school-book" problems using the advanced mathematical methods is often overlooked and neglected. This article illustrates how this formula can be derived in various ways. Such a comparison will not only encourage the reader to explore and understand how and why do mathematical techniques work, but it will also help understand a common thread between different branches of mathematics. This exercise also shows that "the best way" to solve a mathematical problem is a misnomer. |
