Deriving the Distance commandmentDistance 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 plot of ground b in harm of y2 and y1 Substituting eqn1 and eqn2Solving for cEqn4 is the hold reflexion of twain points in hellion dimensionsDistance Formula in cardinal DimensionsIn three dimensions where P1 is (x1 ,y1 ,z1 ) and P2 is (x2 ,y2 ,z2 , the solution suffices in devil step . premier we get the surpass development P1 (x1 ,y1 and P2 (x2 ,y2 ) with our line of site in z-axis then we get c using the withdrawnness economy of two dimensionThen the place c forms another right trigon with the third dimension surmount z2-z1 if we rotate the axis and progress to the line where c lies as one of the axis and apply Pythagorean theorem againSubstituting eqn 4 to eqn 5 becomesSolving for dEqn 7 is the remoteness practice in three dimensionsReal intent ApplicationsOne application of the distance design is in finding the law of continuation of a rope that you claim to tie the tip of two post T1 and post T2 of variant lengths h1 and h2 together knowing just the length of the posts h1 and h2 , and distance among the post X1 . Measuring the distance of the tips directly would be problematic and inconvenient beca design 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 ordinate system as shown in figure2 so that the tip of T1 is at (h1 ,0 ) and the tip of T2 is at (h2 ,X1 . apply the distance formula , the length L can be measured asType equation hereFigure 2 .
