Hello all, I've been thinking about the concept of the functional derivative all night/day but I still can not see the practical meaning of such a measure. Scalar derivative - no problem. It is simply the rate of change wrt the scalar variable. But when you have a function argument, and you...

Homework Statement If V=exp [ \int^{T}_{0}s(t)dt ] Homework Equations What is dV/ds(k), where 0<k<T What does this derivative even mean?? The Attempt at a Solution write V=exp(Y) dV/ds(k) = dV/dY . dY/ds(k) =V.\int^{T}_{0}ds(t)/ds(k)dt =V because ds(t)/ds(k) = 0 for all t except...
