Find the unit vector in the direction of sum of two vectors ⃗v = (2, −4) and ⃗w = (−3, 2). Solution: the sum of two given vectors, we call it ⃗c, is calculated as below. ⃗c = ⃗v + ⃗w = (2, −4) + (−3, 2) = (2 + (−3), −4 + 2) = (−1, −2) The magnitude of this vector is also found as √. ⃗c| = p(−1)2 + (−2)2 = 5.
