  2. Terminal and nonterminal symbols - Wikipedia

    en.wikipedia.org/wiki/Terminal_and_nonterminal...

    Applying the rules recursively to a source string of symbols will usually terminate in a final output string consisting only of terminal symbols. Consider a grammar defined by two rules. In this grammar, the symbol Б is a terminal symbol and Ψ is both a non-terminal symbol and the start symbol. The production rules for creating strings are as ...

  3. Angle - Wikipedia

    en.wikipedia.org/wiki/Angle

    Two angles that share terminal sides, but differ in size by an integer multiple of a turn, are called coterminal angles. The reference angle (sometimes called related angle) for any angle θ in standard position is the positive acute angle between the terminal side of θ and the x-axis (positive or negative).

    For example, the right arm and leg are controlled by the left, contralateral, side of the brain. Ipsilateral (from Latin ipse 'same'): on the same side as another structure. [25] For example, the left arm is ipsilateral to the left leg. Bilateral (from Latin bis 'twice'): on both sides of the body. [26]

    Side-by-side arrivals and departures on a single level is the simplest option for small airports that do not use the jet bridges; Side-by-side arrivals and departures on two levels uses a street-level car traffic at the landside interface, with elevators and lifts bringing the passengers to and from the upper (boarding) level with jet bridges;

  6. Trigonometry - Wikipedia

    en.wikipedia.org/wiki/Trigonometry

    Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') [1] is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.

  7. Terminal moraine - Wikipedia

    Terminal moraine of Wordie Glacier, Greenland Map of the Salpausselkä terminal moraines in Southern Finland. A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by ...

  8. Terminal (electronics) - Wikipedia

    en.wikipedia.org/wiki/Terminal_(electronics)

    Terminal symbol A terminal strip, to which wires can be soldered. A terminal is the point at which a conductor from a component, device or network comes to an end. [1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.

  9. Regular grammar - Wikipedia

    en.wikipedia.org/wiki/Regular_grammar

    A → w, where A is a non-terminal in N and w is in a (possibly empty) string of terminals Σ * A → wB , where A and B are in N and w is in Σ * . Some authors call this type of grammar a right-regular grammar (or right-linear grammar ) [ 1 ] and the type above a strictly right-regular grammar (or strictly right-linear grammar ).
