The formula finds the average of the 2 distances. Distance formula Algebraic expression that gives the distances between pairs of points in terms of their coordinates see coordinate system. Walk through deriving a general formula for the distance between two points.
Given two points x 1 y 1 x 2 y 2 the formula for distance is calculated with the following formula.
Heres how we get from the one to the other. Distance formula Algebraic expression that gives the distances between pairs of points in terms of their coordinates see coordinate system. The distance between x 1 y 1 and x 2 y 2 is given by. Displaystyle dsqrt Delta x2Delta y2sqrt x_2-x_12y_2-y_12.
