Ok SO let U ={u1, u2, ..., un}

let V = {v1,...vn}

let V perp = {x1,x2,..., xn}

let U perp = {w1,...wn}

certainly u1 . w1 = 0

(u1 + u2 ) . (w1+w2) = 0

cu1 . cw1 = 0

everything till now is pretty much basically understood

i can't find a wayu to maek a proof work... Any hints would be appreciated!

I really want to be able to get this one!
