In cartesian coordinates it is typical to use i, j and k to represent unit vectors in the x, y and z directions respectively.nit Vectors.

Enchantments, often shortened to Enchants, are special abilities that can be applied to any piece of Armor or certain tools whilst using an Enchantment Table. When a piece of armor or a tool is enchanted, It will glow, much like a potion, allowing the holder (and anybody else) to see that the item is enchanted. It is also to be noted that an enchanted item will display any current enchantments and their level of strength on the item if examined in the inventory. Using the Enchantment Table method only allows the player to enchant all Armors, Shovels, Pickaxes, Axes, Swords and the Bow.
