On the use of nonstandard finite difference methods
KC Patidar - Journal of Difference Equations and Applications, 2005 - Taylor & Francis
Many real life problems are modelled by differential equations, for which analytical solutions
are not always easy to find. One of the most difficult problems is how to solve these …
