Best ResponseYou've already chosen the best response.0is it when u cross v=0 tells that u is orthogonal to v? I can't remember

Best ResponseYou've already chosen the best response.0Question is rarely asked like this. Usually you are given 2 vectors. I imagine if you find the dell, that would be orthogonal.

Best ResponseYou've already chosen the best response.0ok so its dot product that tells us if two vectors are othogonal if u dot v=0 then u and v are othogonal v=(1,1,1) and u=(u1,u2,u3) u dot v=u1+u2+u3=0 you choose values for u1,u2,u3 as long as the sum =0
