Some Observations Concerning Solutions of Ordinary Differential Equations In Section section, II, we a solution of a differential equation was defined. In this some investigate properties of such solutions. To motivate our discussion, let us consider the following simple example. Let X where A and B = Asmlt + B cos It are constants. By differentiation, dx — = 2A cos 2t - 2B (1) we have sin 2t (2) dt ^ = -4A The right-hand side of (3) is —4 sm 2t - 4S times that of cos 2t (3) Hence, (1).

To Solution of the Equations. These equations need to be solved, subject conditions arrived at from the physical problem, to determine the unknown, or unknowns, involved. The procedures involved may yield an where exact solutions cannot be obtained, approximate solutions. Often, recourse is made to the use of machinery in numerical computations. In the consideration of solutions, one should naturally keep in mind the questions of existence and uniqueness which were exact solution or, in cases previously raised.
