How do you find the unit vector in the direction of the vector a = 2i + 3j? Precalculus Vectors in the Plane Unit Vectors 1 Answer sjc Oct 26, 2016 #vec(hata)=sqrt13/13(2veci+3vecj)# Explanation: unit vector in direction of #veca# is given by #vec(hata)=veca/|a|# so for #veca=2veci+3vecj# #vec(hata)=1/sqrt(2^2+3^2)(2veci+3vecj)# #vec(hata)=1/sqrt13(2veci+3vectj)# #vec(hata)=sqrt13/13(2veci+3vecj)# Answer link Related questions What is a unit vector?
