The simple Euler method: yn = yn 1 +hf(yn 1); h = xn xn 1 can be made more accurate by using either the mid-point or the trapezoidal rule quadrature formula: yn = yn 1 +hf ... Methods have been found based on Gaussian quadrature. Later this extended to methods related to Radau and Lobatto quadrature.

Simple Pendulum by Lagrange’s Equations We first apply Lagrange’s equation to derive the equations of motion of a simple pendulum in polar coor­ dinates. This is a one degree of freedom system. However, it is convenient for later analysis of the double pendulum, to begin by describing the position of the mass point m 1 with cartesian ...
