Why study it? Well because you often can't find "closed form algebraic solutions" to many (most) interesting or economically pressing problems. Numerical methods are the answer to that. Some examples: most simulators of physical phenomena you s. In mathematics the Lyapunov exponent or Lyapunov characteristic exponent of a dynamical system is a quantity that characterizes the rate of separation of infinitesimally close tatively, two trajectories in phase space with initial separation vector diverge (provided that the divergence can be treated within the linearized approximation) at a rate given by.

On the numerical solution of ordinary differential equations. In a sense, therefore, the book breaks with tradition in that it does no longer attempt to deal with all major topics of numerical mathematics.

It is felt by the author that some of the current subdisciplines. This paper deals with the long-time behaviour of numerical solutions of delay differential equations that have asymptotically stable periodic orbits.

The solution procedure is iterative, with the accuracy of the estimated solution improving with each.

Iterative methods are more common than direct methods in numerical analysis. Some methods are direct in principle but are usually used as though they were not, e.g. GMRES and the conjugate gradient method. For these methods the number of steps needed to obtain the exact solution is so large that an approximation is accepted in the same manner as for an iterative method.
