    For both SSS and SAS systems, the instantaneous area coverage for a two-sided system (i.e both port and starboard sensor) is: I A C R = 2 ( R − r ) v {\displaystyle IACR=2(R-r)v} Where R {\displaystyle R} is the max ground range and r {\displaystyle r} is the shortest ground range before the Nadir gap, and v {\displaystyle v} is the speed of ...

  3. List of mathematical examples - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_examples

    This page will attempt to list examples in mathematics. To qualify for inclusion, an article should be about a mathematical object with a fair amount of concreteness. Usually a definition of an abstract concept, a theorem, or a proof would not be an "example" as the term should be understood here (an elegant proof of an isolated but particularly striking fact, as opposed to a proof of a ...

    The primary reason for such advocacy is that computer algebra systems represent real-world math more than do paper-and-pencil or hand calculator based mathematics. [12] This push for increasing computer usage in mathematics classrooms has been supported by some boards of education. It has even been mandated in the curriculum of some regions. [13]

    Case 1: three sides given (SSS). The cosine rule may be used to give the angles A, B, and C but, to avoid ambiguities, the half angle formulae are preferred. Case 2: two sides and an included angle given (SAS). The cosine rule gives a and then we are back to Case 1. Case 3: two sides and an opposite angle given (SSA).

    Convolution. Cauchy product –is the discrete convolution of two sequences; Farey sequence – the sequence of completely reduced fractions between 0 and 1; Oscillation – is the behaviour of a sequence of real numbers or a real-valued function, which does not converge, but also does not diverge to +∞ or −∞; and is also a quantitative measure for that.

    The SAS were tasked with assaulting 2 of the dwellings whilst Delta Force assaulted another 2 dwellings; both of Delta's and one of the SAS's target buildings were cleared without incident, but as the SAS assaulted their final dwelling the assault team were wounded by a hail of fire and an RPG-7 rocket, they returned fire and withdrew from the ...

  9. Shamir's secret sharing - Wikipedia

    en.wikipedia.org/wiki/Shamir's_secret_sharing

    The following example illustrates the basic idea. Note, however, that calculations in the example are done using integer arithmetic rather than using finite field arithmetic to make the idea easier to understand. Therefore, the example below does not provide perfect secrecy and is not a proper example of Shamir's scheme.
