Books by Ponkog Kumar Das

Contains an account of numerical solutions of differential equations of elementary problems of Physics using Euler and 2nd order Runge-Kutta methods and Mathematica 6.0. The problems are motion under constant force, motion under Hooke's law force, and motion under a combination of Hooke's law force and a velocity dependent damping force.

Contains an extensive illustration of use of the finite difference method in solving the boundary value problem numerically. A wide class of differential equations are numerically solved in this book. Starting with differential equations of elementary functions like hyperbolic, sine and cosine, the book solves special functions such as Hermite.
