WebJan 31, 2024 · The cross product of a vector with any multiple of itself is 0. This is easier shown when setting up the matrix. The second and third rows are linearly dependent, since you can write one as a multiple of the other. Then, the determinant of the matrix and therefore the cross product is 0. WebFor a = 3i+j−k and b = i− 4j +2k, find a× b and check that it is perpendicular to both a and b. Solution. The indicated cross product is a ×b = det 0 @ i j k 3 1 −1 ... j+det µ 3 1 −4 2 ¶ k = −2i− 7j− 13k To check the perpendicularity, compute the relevant dot products: a ·(a× b) = (3i +j− k)·(−2i −7j − 13k) = −6 ...
Webi 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 b1 b3 So the 2nd value is -[(a1*b3)-(a3*b1)] = (a3*b1)-(a1*b3). Note: a good way to check your answer for a cross product of two vectors is to verify that the dot product of each original vector and your answer is zero.
