WebThe dot product will always give us a scalar quantity and not a vector quantity. The same is true when calculating the magnitude. Finally, we saw that if two vectors are perpendicular, then their dot product is equal to zero. WebWhen dealing with vectors ("directional growth"), there's a few operations we can do: Add vectors: Accumulate the growth contained in several vectors. Multiply by a constant: Make an existing vector stronger (in the same direction). Dot product: Apply the directional growth of one vector to another. The result is how much stronger we've made ...
