If the angles formed by three coplanar vectors a, B and C are equal, and ㄧ a ㄧ = 1, ㄧ B ㄧ = 2, and ㄧ C ㄧ = 3, then ㄧ a + B + C ㄧ = 3

If the angles formed by three coplanar vectors a, B and C are equal, and ㄧ a ㄧ = 1, ㄧ B ㄧ = 2, and ㄧ C ㄧ = 3, then ㄧ a + B + C ㄧ = 3

If the angles of three coplanar vectors are equal, there are only two cases
One is that the directions of the three vectors are the same, and the angle between any two vectors is 0 °. Then: ㄧ a + B + C ㄧ = 6
Second, if the angle between the three vectors is 120 degrees, then ㄧ a + B + C ㄧ = under the radical (9-radical 3)
