List of derivations for exam
The following is a list of derivations which you might be asked to carry out on the exam. I cannot guarantee that the absence of a derivation from this list means it will not feature on an exam question.
- The Euler-Lagrange equations from the principle of least action
- Hamilton's equations from the modified principle of least action
- Conservation of canonical momentum conjugate to a cyclic coordinate
- Conservation of the hamiltonian in Lagrange framework
- Conservation of the hamiltonian in Hamilton framework
- H=T+V if T is quadratic in velocities and V does not depend on velocities
- Hamilton's equations from the Euler-Lagrange equations
- Poisson equation of motion df/dt = {H,f} + ∂f/∂t
- Poisson bracket relations, eg. {fg,h} = f{g,h} + g{f,h}
- Poisson theorem (using Jacobi identity)
- Two-body to 1-body reduction, reduced mass
- Kepler 2
- Kepler 3 given formulae for a, b, e
- Orthogonality of rotation matrices
- Rotational kinetic energy, inertia tensor
- Angular momentum and the inertia tensor
- Rotation of inertia tensor
