Definition of distance formula in English English dictionary
Any algebraic expression that gives the distance between two points in a particular coordinate system in a particular number of dimensions
Algebraic expression that gives the distances between pairs of points in terms of their coordinates (see coordinate system). In two-and three-dimensional Euclidean space, the distance formulas for points in rectangular coordinates are based on the Pythagorean theorem. The distance between the points (a,b) and (c,d) is given by SquareRoot((a -c)^2 + (b -d)^2). In three dimensional space, the distance between the points (a, b, c) and (d, e, f) is SquareRoot((a -d)^2 + (b -e)^2 + (c -f)^2)
