We can infer that vectors and - are in opposite direction and the angle between them is 180° . Then we express ε_{2 =} 180° + ε_1. ∴ we have . Hence does not uniquely determine the direction of as it gives directions for both and -.

Let ε1 and ε2 be the angles made by and - with the positive X-axis. Show that Thus, giving tan ε does not uniquely determine the direction of

Let ε₁ and ε₂ be the angles made by and - with the positive X-axis. Show that Thus, giving tan ε does not uniquely determine the direction of
