After 1 month of self-imposed exile to Med School Island (my apologies for the long wait btw), I'm finally back with a video! This time, I've made a tutorial on deriving the Beltrami Identity for Calculus of Variations. The Beltrami Identity is an equation which arises from the Euler-Lagrange equation when the integrand of the functional has no explicit or direct dependence on the independent variable x.
This was originally supposed to be part of my Brachistochrone problem video, but I decided to make it an independent topic to avoid confusion.
Questions/requests? Let me know in the comments!
