How to take partial derivative with respect to a derivative? I have a Hamiltonian function, $H(p,q)$ which is a function of $p$ and $q$: $$H(p,q) = p^2 + q^2$$ and I also have a Lagrangian via the Legendre transform...
The notation here is slightly confusing. $L$ is really just a function of three _a priori_ unrelated variables. Consequently $\frac{\partial L}{\partial \dot{q}}$ is just the partial derivative with respect to the third argument of $L$, which in your case is just $p$. The fact that the third argumen...

respect to we get a term involving on the right hand side of the costate equations. Using a wrong convention here can lead to incorrect results, i.e. a costate equation which is not a backwards difference equation). wikipedia.org
