เกี่ยวกับเครื่องคิดเลขนี้

the distance formula, d = √((x₂ − x₁)² + (y₂ − y₁)²), is simply the Pythagorean theorem applied toagrid: the horizontal and vertical gaps are the two legs ofaright triangle and the distance is the hypotenuse. Between (0, 0) and (3, 4), Δx = 3 and Δy = 4, so d = √(3² + 4²) = √(9 + 16) = √25 = 5.This calculator is the everyday tool for map distances, the length ofaline segment, the magnitude ofavectors, and nearest-neighbor comparisons in data. Any two points onaplane have exactly one straight-line distance between them.This calculator is the everyday tool for map distances, the length ofaline segment, the magnitude ofavectors, and nearest-neighbor comparisons in data.This calculator is the everyday tool for map distances, the length ofaline segment, the magnitude ofavectors, and nearest-neighbor comparisons in data.This calculator is the everyday tool for map distances, the length ofaline segment,The distance formula, d = √(x₂ − x₁)² + (y₂ − y₁)²), is simply the Pythagorean theorem applied toagrid: the horizontal and vertical gaps are the two legs ofaright triangle and the distance is the hypotenuse.

Because the differences are squared, the order of the points does not change the result, and negative coordinates work fine.This calculator finds the straight-line distance between two points (x₁, y₁) and (x₂, y₂) using the distance formula, and also reports the horizontal change (Δx), the vertical change (Δy), and the midpoint of the segment, withaplot of the two points.
