In vector analysis, the **baccab formula** gives the expansion of a vector triple product

where the symbol "×" stands for a cross product between two vectors (resulting into a vector) and the symbol "•" stands for an inner product of two vectors (resulting into a scalar).

The name of the formula is because of the mnemonics: "abc = baccab".
