Distance Formula

としても知られています: Euclidean Distance

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

d = √((x₂ - x₁)² + (y₂ - y₁)²)

計算内容

Finds the straight-line distance between two points in a 2D plane. Derived directly from the Pythagorean theorem.

シンボル	名前	ユニット	説明
d	Distance	—	Distance between two points
(x_1, y_1)	Point 1	—	Coordinates of the first point
(x_2, y_2)	Point 2	—	Coordinates of the second point

1d = √((4-1)² + (6-2)²)

2d = √(9 + 16) = √25 = 5

結果: 5
