    en.wikipedia.org/wiki/Linnett_Double-Quartet_Theory

    As an example, the cyanide (CN) radical shown below is a type (a) radical that has ten bonding electrons, while the cyanogen molecule (a dimeric combination of two CN radicals) has 14 bonding electrons. (a) The top shows both the dot-and-cross diagram and the simplified diagram of the LDQ structure of the CN radical.

  4. Screw theory - Wikipedia

    en.wikipedia.org/wiki/Screw_theory

    A common example of a screw is the wrench associated with a force acting on a rigid body. Let P be the point of application of the force F and let P be the vector locating this point in a fixed frame. The wrench W = (F, P × F) is a screw.

  5. Vector Analysis - Wikipedia

    The second chapter introduces the dot and cross products for pairs of vectors. These are extended to a scalar triple product and a quadruple product. Pages 77–81 cover the essentials of spherical trigonometry , a topic of considerable interest at the time because of its use in celestial navigation .

  6. Cross-correlation - Wikipedia

    en.wikipedia.org/wiki/Cross-correlation

    Also, the vertical symmetry of f is the reason and are identical in this example. In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other. This is also known as a sliding dot product or sliding inner-product. It is commonly used for searching a long signal ...

  7. Cross product - Wikipedia

    en.wikipedia.org/wiki/Cross_product

    The cross product with respect to a right-handed coordinate system. In mathematics, the cross product or vector product (occasionally directed area product, to emphasize its geometric significance) is a binary operation on two vectors in a three-dimensional oriented Euclidean vector space (named here ), and is denoted by the symbol .
