Example 16 Find the projection of the vector = 2 + 3 + 2 on the vector = + 2 + . Projection of vector on = | | ( . ) = 2 + 3 + 2 = 1 + 2 + 1 ( . ) = (2 1) + (3 2) + (2 1) = 2 + 6 + 2 = 10 Magnitude of = 12+22+12 = 1+4+1 = 6 Projection of vector on = 1 | | ( . ) = 1 6 (10) = 10 6 = 10 6 6 6 = 10 6 6 = Thus projection of on is 5 3 6
