I was wondering, Lagrangian was the one who invented Variational calculus. He was the one who got Lagrange's equation in physics. He arrived at the concept of Functionals. What did Hamilton did then? Because if Lagrange put Functional as L. He would arrive at same conclusion as Hamilton.

In Brachistochrone problem according to my calculation y dot=√{1/(c^2*y)-1}. Where is my fault?

I missed the integration by parts at 29:10, why do we write only the second term?

Can anyone help me with the step at 29:13 ?
Where does the negative sign come from and how can we pull "eta " out?
