Hi, I am a graduate student. My major is mechanical engineering. I have some problem to derive a equation of motion. So, I decide to use Mathematica. But, I can not find the method to derive the equation of motion from the form of the energys(Kinetic energy and potential engery). Though, The add-on package, which is called EulerEquations at Calculus`VariationalMethods, has a function to derive the equation of motion, but the package does not derive the boundary conditions. I need both the equation of motion and the boundary contions. How to derive both the equation of motion and the boundary contions. Please, let me know to derive the equation of motion and the boundary contions.
