Cross Product - Illinois Institute of Technology
The volume of the parallelepiped determined by the vectors a, b, and c is the magnitude of their scalar triple product: V = a · (b x c) where, If the triple scalar product is 0, then the vectors must lie in the same plane, meaning they are coplanar

11 Vector Algebra - Auckland
The triple scalar product, or box product, of three vectors u, v, w is defined by u v w v w u w u v Triple Scalar Product (1 1 4) Its importance lies in the fact that, if the three vectors form a right-handed triad, then the volume V of a parallelepiped spanned by the three vectors is equal to the box product
81 Volumes
resulting volume is called the volume of solid and it is defined to be The volume of solid does not necessarily have to be circular It can take any arbitrary shape One useful way to find the volume is by a technique called “slicing ” To explain the idea, suppose a solid is positioned on the axis and extends from points to (Figure 6)
Chapter 8 Vectors and Scalars - PBTE
The vectors other than zero vectors are proper vectors or non-zero vectors 8 Equal Vectors: Two vectors a and b are said to be equal if they have the same magnitude and direction If and are equal vectors then = 9 Parallel and Collinear Vectors: The vectors and are parallel if for any real number n, = n If (i) n > 0 then the
Vector Calculus and Multiple Integrals
Cross product of parallel vectors is zero It anti-commutes: a x b = - b x a It does not associate: a x (b x c) ≠ (a x b) x c Scalar triple product The scalar triple product (axb) c gives the volume of the parallelepiped who sides are the vectors a, b, c 4

Show that no value of p makes the vectors a = 2p i + j - 3 k and b = - 7 i + p j - k parallel For the vectors to be parallel, we require a x b = 0 We have, a x b = − + + 2 3 1 2 21 2 7 p p p The third component obviously cannot equal 0 Hence, this vector clearly cannot equal 0
Reciprocal Lattice
Reciprocal lattice vectors • The cross product defines a vector parallel to with modulus of the area defined by and • The volume of the unit cell is thus given by • We can define the reciprocal lattice vectors , and in terms of direct lattice vectors
Vectors, Matrices and Coordinate Transformations
Examples of physical vectors are forces, moments, and velocities Geometrically, a vector can be represented as arrows The length of the arrow represents its magnitude Unless indicated otherwise, we shall assume that parallel translation does not change a vector, and we shall call the vectors satisfying this property, free vectors
