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 =(2,−1,−2), b =(4,−3,0), and c =(−2,1,6). calculate the following, and express your answers as ordered triplets of values separated by commas.
