Given that with the constraint on y(x) such that and the end condition y(0)=0 and y(1)=1, prove that F{y(x)} achieves its minimum value for y = x

-this is length of a curve from (0,0) to (1,1). Its length is sqrt(2) only if it is a straight line. y=x. May be it may be solved to get this solution. Without length restriction F min is sinx/sin1.
