WebThe cross product could point in the completely opposite direction and still be at right angles to the two other vectors, so we have the: "Right Hand Rule". With your right-hand, point your index finger along vector a, and point your middle finger along vector b: the cross product goes in the direction of your thumb.
WebBecause the cross product of two vectors is a vector, it is possible to combine the dot product and the cross product. The dot product of a vector with the cross product of two other vectors is called the triple scalar product because the result is a scalar. chrome app apkWeb= i(16) − j(3) + k(−7) = − − b) Using determinants we get 16, 3, 7 2 −1 5 i j k (i +2j) × (2i − 3j) = 1 2 0 = i(0) − j(0) + − − Multiplying directly and using i × 2 k( 7) = 7k. −3 0 j = k etc we get (i +2j) × (2i − 3j) = i × i − 3i × j +4j × i − 6j × j = 0 − 3k − 4k − 6 · … ghms noticeWebAnswer to Question #59204 in Linear Algebra for RITA.
