WebA useful way to think of the cross product x is the determinant of the 3 by 3 matrix i j k a1 a2 a3 b1 b2 b3 Note that the coefficient on j is -1 times the determinant of the 2 by 2 matrix a1 a3 ... If both dot products are zero, this does not guarantee your answer is correct but makes your answer likely correct. If at ... WebThere is an easy way to remember the formula for the cross product by using the properties of determinants. Recall that the determinant of a 2x2 matrix is and the determinant of a 3x3 matrix is Notice that we may now write the formula for the cross product as Example The cross product of the vectors a=<3,-2,-2> and b=<-1,0,5> is
