So I'm just having a bad night about Lagrangian and Hamiltonian mechanics and I was deriving them all over again and just wanted to try to differenciate the derivation with respect to velocity instead of x (just for fun)(adsbygoogle = window.adsbygoogle || []).push({});

But I kind of struggled with the math and I just want to get this right with the chain rule

If F is a function of x and V and V a function of x aswell and I want to differentiate F with respect to V

dF/dV = dF/dx . dx/dV

Is it really this way?

I kind of took the formula from the post at the bottom here: -> https://www.physicsforums.com/showthread.php?t=282120

But i don't really understand what that comes from.. is ti true the equations that guy wrote? i've never seen the chain rule that way
