Distance Formula

1. The Distance Formula is used to calculate the Distance between any 2 Points.
2. The Distance \(D\) between any 2 Points \( (x_1,y_1)\) and \((x_2,y_2)\) in \(2\)-Dimensional Cartesian Coordinate System is calculated as
   
   \(D=\sqrt {(x_2 - x_1)^2 + (y_2 - y_1)^2 }\)
3. The Distance \(D\) between any 2 Points \( (x_1,y_1,z_1)\) and \((x_2,y_2,z_2)\) in \(3\)-Dimensional Cartesian Coordinate System is calculated as
   
   \(D=\sqrt {(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2 }\)
4. The Distance \(D\) between any 2 Points in \(N\)-Dimensional Cartesian Coordinate System can be calculated similarly.
