Differential Equations Are Called Fractional Differential Equations (Pde) or Normal Differential Equations (Tribute) As Indicated By Whether They Contain Incomplete Derivatives. the Order of a Differential Equation Is the Highest Order Derivative Happening. an Answer (Or Specific Arrangement) of a Differential Equation of Order N Comprises of a Capacity Characterized and N Times Differentiable on an Area D Having the Property That the Useful Equation Gotten By Substituting the Capacity and Its N Derivatives into the Differential Equation Holds For Each Point In D. In This Paper Classification of Differential Equation Is Done and Finite Difference Method Is Additionally Introduced.
