 Question 166634: Find // v // if v = -5 i + 12 j Find the unit vector having the same direction as v, if v = - 5 i + 12 j Answer by jim_thompson5910(28536)   (Show Source): You can put this solution on YOUR website!Since , this means that So for any vector the magnitude or norm of that vector is: So in this case So Geometrically, this means that the length of is 13 units -------------------------------- To find the unit vector that has the same direction as , simply divide EACH component of the vector by the length of the vector . So... So the unit vector that has the same direction as is
