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 ground of x2 and x1 while b in toll of y2 and y1 Substituting eqn1 and eqn2Solving for cEqn4 is the hold formula of twain points in demon dimensionsDistance Formula in Three DimensionsIn three dimensions where P1 is (x1 ,y1 ,z1 ) and P2 is (x2 ,y2 ,z2 , the solution bob ups in 2 step . First we get the surpass exploitation P1 (x1 ,y1 and P2 (x2 ,y2 ) with our line of site in z-axis then we get c using the withdrawnness formula of two dimensionThen the place c forms another right triangle with the third dimension remoteness z2-z1 if we rotate the axis and make the line where c lies as one of the axis and apply Pythagorean theorem againSubstituting eqn 4 to eqn 5 becom esSolving for dEqn 7 is the duration formula in three dimensionsReal nose drops ApplicationsOne application of the distance formula is in finding the law of continuation of a rope that you need to tie the tip of two post T1 and post T2 of different lengths h1 and h2 together knowing and the length of the posts h1 and h2 , and distance between the post X1 . Measuring the distance of the tips directly would be difficult and inconvenient beca call of the need of come up at the two posts .

So that we can use the distance formula by plotting the two post in a rectangular coordinate system as shown in figure2 so that the tip of T1 is at (h1 ,0 ) and the tip of T2 is at (h2 ,X1 . use the distance formula , the length L can be meas! ured asType equation hereFigure 2 .
