Question

Find a vector a with representation given by the directed line segment AB. Draw AB and the equivlent representation starting the origin. A(0,3,1), B(2,3,-1)

Answer 1

AB = (2, 0, -2)

Explanation:

The vector is of the form, AB = (B1 - A1, B2 - A2, B3 - A3)

A = (0, 3, 1)

B = (2, 3, -1)

AB = (2 - 0, 3 - 3, -1 - 1)

AB = (2, 0, -2)
