In calculus of variation, we use Euler's equation to minimize the integral.
e.g. ∫f{y,y' ;x}dx
why we treat y and y' independent ?

why we treat y and y' independent ?
Because there is no algebraic relation between a function and its derivative.
This is why you need boundary conditions to solve differential equations.
