4.6.18 Consider the linear Lagrangian function L in R² given by L (t, x,x) = a (t, x) + B (t, x) x, and the corresponding variational problem with t₁ ≤ t ≤ t₂. Write down the Euler-Lagrange equation. What happens with the excess function? Comment on the situation. The following problems deal with the Poisson brackets.
