[tex]J[y]=\int_{a}^{b}dx(p(x)(y`)^{2}+V(x)y^{2}) [/tex]

[tex]\int_{a}^{b}y^{2}dx=C [/tex] with c a constant...

then what conditions should p and V(x) function fulfill in order to the functional have an extremum?..

(This isn't the first time you've done this: you've had some pretty serious bugs in your LaTeX before too)
