Previous: The Laplacian Operator,
As in vector there are two types of triple vector products that
compare with the scalar triple product (that gives the area of a
parallelopiped) and the vector triple product. There are differences
due to the operator nature of
. So what about
? Remember the vector rule
Using operator rules
Now including the vector rules
but in the second term the operator must act on
. So we
reverse the order of the last term to give

An important rule is similar to the vector triple product, namely
. This rule will be covered in
a tutorial question but we use the vector rule
