WebYou have to add all pairs of W 1 and W 2 . So, formally. W 1 + W 2 = { w 1 + w 2 ∣ w 1 ∈ W 1 and w 2 ∈ W 2 }. For example the sum of two lines (both containing the origo) in the space is the plane they span. Anyway, it is worth to mention, that W 1 + W 2 is the smallest subspace that contains W 1 ∪ W 2. Share. WebSo vector a, just like that. And one way of thinking about subtracting vector b is instead of adding vector b the way we did here, we could add negative b. So negative b would have the same magnitude but just the opposite direction. So that's vector a. Vector negative b will still start right over here, but will go in the opposite direction.
