if F(x,y)=F(y,x) and x+y=c (constant)  prove that F_(max or min) =F((c/2),(c/2)).
ifF(x,y)=F(y,x)andx+y=c(constant)provethatFmaxormin=F(c2,c2).

what is the difference between F(x,y) and F(y,x)

e.g.  F(x,y)=sin (x) × sin (y)  F(y,x)=sin (y) × sin (x)=F(x,y)
e.g.F(x,y)=sin(x)×sin(y)F(y,x)=sin(y)×sin(x)=F(x,y)
