The 3D distance formula extends the Pythagorean theorem into three dimensions. The distance between two points (x₁,y₁,z₁) and (x₂,y₂,z₂) is the square root of the sum of squared differences in each coordinate.

공식

d = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²)
d
√((x₂−x₁)² + (y₂−y₁)²) — √((x₂−x₁)² + (y₂−y₁)²)

단계별 가이드

  1. 1d = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²)
  2. 2This is the straight-line (Euclidean) distance in 3D space
  3. 3For 2D: remove the z component → d = √((x₂−x₁)² + (y₂−y₁)²)
  4. 4Useful in physics (particle positions), computer graphics, GPS calculations
