Question

If vector v has an initial point at P1 and a terminal point at P2, write v as multiples of the basis vectors That is, write v in the form v = ai + bj.

P1 = (2, 0), P2 = (40, 0) and v = ?

Answer 1

38i +0j

Explanation:

v = P2 -P1 = (40-2, 0 -0) = (38, 0)

In terms of basis vectors i and j, this is ...

v = 38i +0j
