Question

To understand the rules for computing cross products. Let vectors: A = (1, 0, -3), B = (-2, 5, 1), and C = (3, 1, 1). Scalar triple product Calculate A middot (B times C). Express your answer numerically. Let V1 and V2 be different vectors with lengths V1 and V2, respectively. Magnitude of the cross product of two perpendicular vectors If V1 and V2 are perpendicular, calculate |V1 times V2|. Express your answer in terms of V1 and V2. Magnitude of the cross product of two parallel vectors If V1 and V2 are parallel, calculate |V1 times V2|. Express your answer numerically.

Explanation / Answer

e) A.(BxC) = (1, 0,-3) .(4,5,-17) = 4 + 51 = 55 f) Magnitude Cross product of two perpendicular vectors = Their Product = V1*V2 g) Magnitude Cross product of two parallel vectors = 0
