Only part A.) of the question
In general it is best to conceptualize vectors as arrows in
space, and then to make calculations with them using
their components. (You must first specify a coordinate
system in order to find the components of each arrow.)
This problem gives you some practice with the
components.
Let vectors A = (1,0, -3), B = (-2, 5, 1), and
C = (3,1,1). Calculate the following, and express your
answers as ordered triplets of values separated by
commas.
