Webb26 maj 2024 · The vector triple product can be simplified by the so-called BAC-CAB rule: (1.17) A × ( B × C) = B ( A ⋅ C) − C ( A ⋅ B). Notice that ( A × B) × C = − C × ( A × B) = − A ( B ⋅ C) + B ( A ⋅ C) is an entirely different vector (cross-products are not associative). WebbAssociations. Associations are a kind of generalization of lists, in which every element has a key as well as a value. Counts is a typical function that produces an association. Counts gives an association that reports how many times each different element occurs: In …

Naturally, our next best approximation would be estimating the function by piecewise quadratic polynomials. To pick the right ones, we should investigate the idea of an interpolating polynomial.
