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. 3A - 2C= -3.-2.-11 -2A + 3B -C = -11, 14. 8 2A - 3(B - C)= 5, - 16, 10

Explanation / Answer

2A = ( 2 i + 0j - 6k)

B-C =( -5 i +4j +0k) = 3(B-C) = -15 i +12j + 0 k

2A - 3(B-C) = ( 17 i -12 j -6k) = 17, 12, 0
