Abstract: In this pager, a second order difference equation is deduced by expanding only the deflection of a beam on one side of the step point .The exact resups of the deflection of the beams, without the distributed forces acting on,
can be obtained in terms of only one or two equations, It is because in this case the difference accuracy of the equation is independent of the length of the difference step.
