CHAPTER 02.10: VECTORS: How do you multiply a vector by a scalar?


In this segment, we would talk about how we would multiply a vector by a scalar. So, if k is a scalar and A is a n-dimensional vector, then if we want to multiply k which is a scalar to the A vector. K times A will be equal to k times whatever A vector is. Letís suppose A vector is a1, a2, all the way up to a sub n. So, if A vector is this and k is scalar then I want to multiply A vector by k. Each component can be multiplied by k so the first component of ka1, ka2, and last kan. So, thatís how you multiply a scalar to a vector. This is the end of this segment.
