    Homework Statement From John Taylor's Classical Mechanics: Show that definition (1.9) of the cross product is equivalent to the elementary deinition that R x S is perpendicular to both R and S, with magnitude rssinθ and direction given by the right hand rule. [Hint: It is a fact (though...

    The cross product is inherently a three-dimensional operation because it produces a vector that is orthogonal to the plane formed by the two input vectors. In higher dimensions, this concept does not generalize in the same way, and different operations are used to produce analogous results.

    www.physicsforums.com/threads/definition-of-cross-product-in-spivaks-calculus...

    The cross product in Spivak's 'Calculus on Manifolds' is a mathematical operation that takes two vectors as inputs and produces a new vector that is perpendicular to both of the input vectors. It is a fundamental concept in vector calculus and is often used in applications such as physics and engineering. 2.

    together with the cross product is an algebra over the real numbers, which is neither commutative nor associative, but is a Lie algebra with the cross product being the Lie bracket. Like the dot product, it depends on the metric of Euclidean space, but unlike the dot product, it also depends on a choice of orientation or "handedness".

    A cross product integral is calculated by taking the cross product of two vectors and then integrating the resulting vector function over a specified region or surface. 3. What is the geometric interpretation of a cross product integral? The geometric interpretation of a cross product integral is the area of a surface in three-dimensional space.

    24. HallsofIvy said: Cyrusabdollahi started by asserting that the cross product of two vectors A and B is defined as |A||B| cos (θ) where θ is the angle between A and B. He then asked for a proof that that is equal to the "determinant" definition. If you want to take the "determinant" as the definition, fine.

    What definition of cross-product are you using? A perfectly good definition is: The cross product of vector u and v is the vector with length equal to length of u times length of v time sine of the angle between u and v, perpendicular to both u and v and directed according to the "right hand rule".

  10. Can the Cross Product be Generalized Using the Dot Product?

    In three-dimensional space, the cross product is only defined for two vectors. However, in higher-dimensional spaces, there are analogues to the cross product that can be defined for more than two vectors. These include the wedge product and the triple cross product, which are used in differential geometry and quantum mechanics, respectively.

    Derivation Product Vector Vector product. In summary, the vector cross product is a definition that has been derived by considering the need for certain properties, such as bilinearity and invariance under rotation, and reducing the possibilities through mathematical reasoning.
