Some nonlinear mechanical problems solved equahion analytical solutions. Filipich 1,2M. Rosales 1,3 and F. Buezas 4. Some of the problems are classical in the related literature and exhibit chaotic behavior in certain ranges of the involved parameters despite being simple-looking deterministic systems. The solutions are approached by means of the old technique of power series to solve ordinary differential equations. The independent variable is time in all the eqyation and elementary recurrence algorithms are obtained.

This is an alternative to nonlinear equation standard numerical techniques and nonlinear equation the theoretical exactness of the response. Several examples are included and trajectories diagrams, phase plots, etc. The desired numerical precision is attained using time steps several times larger than the usual ones. The availability of equstion analytical solution may be an additional tool within a standard qualitative analysis.

The solution of nonlniear order problems and governed by partial differential equations is under study. Power series is an old technique to solve ordinary differential equations ODE's. A wide open literature is available on the subject. Simmons,Coddington,Kreyszig, may be useful as references in this methodology. The efficiency of this standard technique in solving linear Nonliinear with variable coefficients is well known. Also an extension known as Frobenious method allows to tackle differential equations with coefficients that are not analytic.

Numerical tools such as time integration schemes e. Runge-Kutta, Newmark method, central difference, see for instance Bathe, are commonly employed to solve nonlinear differential problems. The authors have addressed similar problems with do online dating sites really work variational method named WEM Rosales and Filipich, The authors have applied power series numerical tools in various problems Filipich and Rosales, a, A method to solve nonlinear differential problems governed by ordinary equations ODEs is herein employed.

The solution is found with an analytical solution using algebraic series. A previous manipulation of the equations leads to very convenient recurrence nonlinear equation which ensure nonlinear equation exactness of the solution as well as the computational efficiency of the method. The approach is straightforward and is illustrated with several problems, i. In all the cases the results are given in plots state variables vs.

Neither divergence nonlinear equation numerical damping was found in any case. The availability of an analytical solution may be also a helpful tool in the qualitative analysis of nonlinear equations. In this section the general algebra of the approach is nonoinear. In order to fulfill an algebraic consistence A. After replacing the series expressions in each factor of this equation, one obtains the next recurrence formula Cauchy products. Now let us expand an analytical function in Taylor series.

The left hand sides of the governing equations are written as. Additionally the expression of this function in power series of t is given by. The functions representing the wind velocity varying with the height are now expanded in Taylor series Eq.

In turn these functions may be expanded in series of t. If we now make use of the A. Let us introduce a simplifying notation. After the above definitions and notations we are able to find a recurrence algorithm to solve the differential system First what does bible say about cleansing us write the differential equations in terms of the series. The necessary recurrence relationships are given by.

Then the algorithm is complete. Briefly the steps are the following. The calculation is thus performed during a number of steps which nonlineae on the value of T and duration nohlinear the experiment. The trajectories xy and z are finally obtained. Figures 1 and 2 show the 3D trajectories for data depicted in Table 1. Figure 1: Projectile motion. Example 1. What is the relationship between risk and return on investment 2: Projectil motion.

Example 2. The behavior of N bodies attracted to what do you mean by independent variable other in a gravitational force field is tackled by means of the statement nonlinear equation the what are some examples of dominant genes solution using algebraic recurrence.

The forces are assumed varying inversely as the square of the separation among the bodies. Let us squation the position vectors of each body in an inertial reference system as. NB is the number of bodies. The prime denotes derivative w. Additionally the following notation was introduced. The following A. Analogously with functions y i and z i.

Other A. For the equatuon of brevity the recurrence expression for all the coefficients introduced above are not included. They are derived from the A. Finally the solving equations are. The next definitions were introduced. The necessary steps to find the solution are the following. Given the initial conditions, i. The calculation is thus performed using Eqs. The spheres denote the initial position of the bodies, which along with the velocities are given in Table 2.

Lorenz see for instance Strogatz, discovered in the chaotic motions of a model of convection rolls in the nonlinear equation. The behavior of this problem nonlinear equation such that very nonlinesr changes in the initial conditions lead to different solutions, but as Lorenz showed, bounded in a three dimensional butterfly-shaped domain. Here the power series are used to solve the following system of differential equations.

After the replacement of the series in the differential system the recurrence system is obtained. The time trajectory is shown in Fig. The well-known strange attractor is reproduced without numerical perturbation. Being very sensitive to initial conditions these problems pose a challenge to any numerical tool. Figure 4: Lorenz attractor. Time trajectory. Figure 5: Lorenz strange attractor. Forced Duffing equation.
