CHAPTER 02.11: VECTORS: How do
you multiply a vector by a scalar? Example In
this segment, will talk about example how do we
multiply a vector by a scalar. So let’s suppose somebody says “Hey, find 3A
if A= 7, 13, 19.” So you are given the A vector, the 3 dimensional vector, 3
components, and somebody says “Hey, can you find 3A so 3A will be simply equal
to 3 times the vector A which is 7, 13, 19?” And all we have to do is
multiply each component of the A vector by 3; so 3*7, 3*13, 3*19 and there
I’ll get 21, 39, 57. So that’s what 3A is so all you have to do is simply
multiply each component by the scalar, and whatever is the result is your
answer. And that is the end of this segment |
