www.math.auckland.ac.nzThe 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.
Lecture L20 - Energy Methods: Lagrange’s
ocw.mit.eduSimple 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 ...
