I'm trying to find a function for x in [0, L] that minimizes this:
[tex] \int_0^{L} A \phi(x) \frac{ d \phi(x) }{dx} + B cos(\phi(x))\ d\mbox{x} [/tex]
For real (given) positve numbers A and B.
with
[itex] \phi(0) = 0 [/itex]
[itex] \phi(x) [/itex] is an increasing positve function.
Can somebody point me in the right direction?
