see dude .., vector a + vector b = magnituge of a + b vector multiply by unit vector . so unit vector = vector a + vector b / magnitude of a + b vector . so , a + b vector = 4i cap + 5 j cap , magnitude = 5+root 2 . so unit vector = 4i cap + 5j cap / 5+ root2Laughing

unit vector means

add the i^ and j^ then divide it by its magnitude

unit vector=4i^ + 5j^/(root41)
