Talk:Poincaré–Miranda theorem

Bounds for the corollary
I think notation should be made uniform throughout the article. In particular, first the unit square is [-1,1]^n but later, in the corollary, sup is taken for x_i=0 and inf for x_1=1, while sup should be considered for x_i=-1; otherwise, unit square should be defined as [0,1]^n.
