1.	What is the general formula for finding the magnitude of the cross product of two vectors a and b with angle θ between them?(a) \|a\|.\|b\|(b) \|a\|.\|b\| cos(θ)(c) \|a\|.\|b\| sin(θ)(d) \|a\|.\|b\| tan(θ)This question was addressed to me in exam.I want to ask this question from Computational Geometry topic in portion Computational Geometry of Data Structures & Algorithms II
Answer» The correct answer is (c) \|a\|.\|B\| sin(θ) Best explanation: The GENERAL formula for finding the MAGNITUDE of cross product of TWO vectors is \|a\|.\|b\| sin(θ). Its DIRECTION is perpendicular to the plane containing a and b.
