This operation is combined with the del operator to find the limiting value of circulation per unit area for certain fields; that is the curl operation. This operation is used to find binormal vectors, the intersection of two planes, and the area of a parallelogram. Often found by taking a three-by-three determinant, the result of this operation is per- pendicular to the two input vectors, and its direction can be determined using the right hand rule. Name this vector operation whose result is equal in magnitude to the

Often found by taking a three-by-three determinant, the result of this operation is per- pendicular to the two input vectors, and its direction can be determined using the right hand rule. Name this vector operation whose result is equal in magnitude to the product of the magnitude of the two vectors times the sine of the angle between them, and that in the scalar triple product is combined with the dot product.
