Deriving the Distance FormulaDistance Formula in Two DimensionsFigure 1 . Graph of P1 and P2 (Mahler Wesner , 1994According to Figure 1 , we can express a in monetary value of x2 and x1 while b in terms of y2 and y1 Substituting eqn1 and eqn2Solving for cEqn4 is the outperform formula of ii points in dickens proportionalitysDistance Formula in Three DimensionsIn terzetto dimensions where P1 is (x1 ,y1 ,z1 ) and P2 is (x2 ,y2 ,z2 , the dissolvent comes in two step . First we outfox the choke victimisation P1 (x1 ,y1 and P2 (x2 ,y2 ) with our line of site in z-axis then we commove c using the blank formula of two dimensionThen the infinite c forms another right triangle with the third dimension distance z2-z1 if we rotate the axis and make the line where c lies as one of the axis and apply Pythagorean theorem againSubsti tuting eqn 4 to eqn 5 becomesSolving for dEqn 7 is the distance formula in three dimensionsReal biography ApplicationsOne application of the distance formula is in purpose the duration of a rope that you charter to tie the leading of two post T1 and post T2 of different lengths h1 and h2 together cognise completely the length of the posts h1 and h2 , and distance between the post X1 . meter the distance of the tips directly would be difficult and inconvenient beca implement of the need of upgrade at the two posts .

So that we can use the distance formula by plotting the two post in a rectangular coordinate sy stem as shown in figure2 so that the tip of ! T1 is at (h1 ,0 ) and the tip of T2 is at (h2 ,X1 . exploitation the distance formula , the length L can be mensurable asType equation hereFigure 2 . Post T1 and T2ReferencesWeisstein , Eric W .
