Best ResponseYou've already chosen the best response.0would that be the cross product of u and v?

Best ResponseYou've already chosen the best response.0or rather, if they exist all inthe same subspace and are orthogonal; then wouldnt the dot products betweenthem be zero?

Best ResponseYou've already chosen the best response.0The vectors themselves are as follows u = 1 over the square root of 2 [1] [ 0] [1] v = 1 over the square root of 6 [1

Best ResponseYou've already chosen the best response.0There is a formula for orthogonal projection but it is usually used between two vectors, you would have to figure out how to use it with a third. For example orthogonal projection of v on u is [(v dot u)/u^2]multiplied by vector u
