Theorem If second order differential equation has the form y00 = f (t,y0), then the equation for v = y0 is the first order equation v0 = f (t,v). In addition, it is important to label the distinct sign charts for the first and second derivatives in order to avoid unnecessary confusion of the following well-known facts and definitions. com is undoubtedly the excellent site to check-out!. To reiterate, the exponents x and y are not derived from the balanced chemical equation, and the rate law of a reaction must be determined experimentally. 1 Introduction Linearization of nonlinear dynamic system was originally investigated by Poincare[1, 2] in terms of homological equations.
