How do you find the unit vector for the following vector that connects (2,-5) and (0,3)? Precalculus Vectors in the Plane Unit Vectors 1 Answer Sarthak Aug 28, 2017 #hat(AB) = (hati-4hatj)/sqrt(17)# Explanation: #vecA = 2hati-5hatj# #vecB = 3hatj# Displacement vector #vec(AB) = vecA - vec B# #vec(AB) = 2hati-5hatj-3hatj# #vec(AB) = 2hati-8hatj# #vec(AB) = |vec(AB)|*hat(AB)# #hat(AB) = vec(AB)/|vec(AB)|# #hat(AB) = (2hati-8hatj)/sqrt(68)# #hat(AB) = (hati-4hatj)/sqrt(17)# Answer link Related questions What is a unit vector?
