# Numerical Methods For Ordinary Differential Equations With Programs

Here, we provided Numerical Methods For Ordinary Differential Equations With Programs. Numerical methods for ordinary differential equations are methods used to find numerical approximations to the solutions of ordinary differential equations (ODEs). Their use is also known as “numerical integration”, although this term can also refer to the computation of integrals.

For practical purposes, however – such as in engineering – a numeric approximation to the solution is often sufficient. The algorithms studied here can be used to compute such an approximation. An alternative method is to use techniques from calculus to obtain a series expansion of the solution. Free download PDF Numerical Methods For Ordinary Differential Equations With Programs.

Ordinary differential equations occur in many scientific disciplines, including physics, chemistry, biology, and economics. In addition, some methods in numerical partial differential equations convert the partial differential equation into an ordinary differential equation, which must then be solved.

The study of differential equations started very soon after the invention of calculus. Sir Isaac Newton in 1676 solved a differential equation by the use of an infinite series. Differential equations have their applications in almost all fields of Science and Technology because it can describe the modeling of nearly all systems undergoing changes. Due to this fact, it finds a central position in Science and Technology from which different lines of development extend in many directions.

It has also widespread applications in the social sciences. Many mathematicians have studied the nature of these equations and many complicated systems can also be described quite precisely with the help of compact mathematical expressions. However, many systems involving the differential equations are so complex, or the systems that they describe are so large, that purely mathematical analysis is not possible and we have to seek approximate solutions by means of numerical methods.

It is in these complex systems, where the computer simulations and numerical approximations are useful. The techniques for solving the differential equations based on the numerical approximations were developed long before programmable computers existed. It was common to see equations solved in the rooms of people working on the mechanical calculators. Free download PDF Numerical Methods For Ordinary Differential Equations With Programs.

As the computers have increased in speed while decreased in cost and as a result of which the complex systems of the differential equations can be solved on a common PC. Currently, even the laptop could compute the long-term trajectories of about one million interacting molecules with relative ease, a problem that was inaccessible to the fastest supercomputers just twenty years ago.

Every-one knows the benefits from well-known topics such as wave mechanics, the theory of heat conduction, solid mechanics, fluid dynamics, electromagnetic and potential theory and we can credit all these benefits due to the differential equations. Further, a great motivating factor for the construction of the computer has been the problem of solving the differential equations occurring in the trajectories of bullets.

In fact, whenever a real-life problem is solved by means of mathematical tools, you may find that most of the time it involves the solution of a system of equations and/or differential equations. Their solutions remain a challenging task and for the application purposes, we are using the approximate solutions working satisfactorily enough.

Mathematical modeling has been steadily and increasingly spreading in the natural and social sciences over the last few decades. It is now well established in vastly different areas spreading from the physical sciences to the biological sciences, environmental sciences, and economics.

Depending on the conditions, the numerical solution of a differential equation can be classified into two parts such as the initial value problems and boundary value problems. The numerical methods which are generally used to find the numerical solution of an initial value problem are the Euler method, Euler-Cauchy method, Runge Kutta fourth-order method, predictor-corrector method, and many others.

The numerical methods which are widely used in the numerical solution of boundary value problems are the finite difference method and finite element method. It has been observed that the finite difference method is used for simple (regular) geometry while the finite element method can be used for both regular as well as irregular geometries.

Numerical analysts have revealed that the finite element method suited well in the fields of solid and structural mechanics. The particular attraction of this method is that the elements may be of arbitrary shapes and can be positioned so as to follow closely the boundary of the interested domain.

In the field of fluid dynamics, it has been observed that the finite element method is in general confined to the solution of those problems where diffusion term dominates compared to convective term i.e. when the flow formation is at a small Reynolds number. There are also other methods such as the shooting method, control volume method, cubic spline method, variational method, and many others that are used to solve the boundary value problems.
