> If you naively compute the distance between them using the familiar Euclidean formula √(a²+b²)
That formula may be familiar, but it doesn’t compute a distance.
A simple demonstration of why this is necessary is to consider the distance between the points 3 and 4. If you naively compute the distance between them using the familiar Euclidean formula √(a²+b²) you get:
That formula may be familiar, but it doesn’t compute a distance.
A simple demonstration of why this is necessary is to consider the distance between the points 3 and 4. If you naively compute the distance between them using the familiar Euclidean formula √(a²+b²) you get:
√(3²+4²) = √(9+16) = √(25) = 5
That can't be right...
