Answer:
Yes.
(Review: ) Are vector addition and column matrix addition both associative?
Yes.
| vector R: | + vector S: | = vector T: |
Now it is your turn. Here are two vectors:
R = ( 4, 3 )T S = ( 1, 2 )T
form the sum:
T = R + S
Do it by column matrix addition, and by the head-to-tail rule. In the picture, click close to the arrowhead of the vector you wish to change and drag it to its new location.
