    But the tables must wrap (one dropping below the other) in narrow screens if horizontal scrolling is to be avoided. Narrow your browser window to see the tables below wrap. This works in mobile view too. Click on "mobile view" at the bottom of any Wikipedia page. These tables are adapted excerpts from versions of Iceland men's national handball ...

  3. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    This has been followed by subsequent spreadsheets, such as Microsoft Excel, and complemented by specialized VLOOKUP and HLOOKUP functions to simplify lookup in a vertical or horizontal table. In Microsoft Excel the XLOOKUP function has been rolled out starting 28 August 2019.

  4. Join (SQL) - Wikipedia

    en.wikipedia.org/wiki/Join_(SQL)

    An inner join (or join) requires each row in the two joined tables to have matching column values, and is a commonly used join operation in applications but should not be assumed to be the best choice in all situations. Inner join creates a new result table by combining column values of two tables (A and B) based upon the join-predicate.

    The right outer join ( ) behaves almost identically to the left outer join, but the roles of the tables are switched. The right outer join of relations R and S is written as R S. [e] The result of the right outer join is the set of all combinations of tuples in R and S that are equal on their common attribute names, in addition to tuples in S ...

  6. Love wave - Wikipedia

    en.wikipedia.org/wiki/Love_wave

    The Love wave is a result of the interference of many shear waves guided by an elastic layer, which is welded to an elastic half space on one side while bordering a vacuum on the other side. In seismology, Love waves (also known as Q waves (Quer: German for lateral)) are surface seismic waves that cause horizontal shifting of the Earth during ...

  7. Euler spiral - Wikipedia

    en.wikipedia.org/wiki/Euler_spiral

    A double-end Euler spiral. The curve continues to converge to the points marked, as t tends to positive or negative infinity.. An Euler spiral is a curve whose curvature changes linearly with its curve length (the curvature of a circular curve is equal to the reciprocal of the radius).

  8. Ship motions - Wikipedia

    en.wikipedia.org/wiki/Ship_motions

    A yaw motion is a side-to side movement of the bow and stern of the ship. The transverse/Y axis, lateral axis, or pitch axis is an imaginary line running horizontally across the ship and through the centre of mass. A pitch motion is an up-or-down movement of the bow and stern of the ship.

  9. Sine wave - Wikipedia

    en.wikipedia.org/wiki/Sine_wave

    In two or three spatial dimensions, the same equation describes a travelling plane wave if position and wavenumber are interpreted as vectors, and their product as a dot product. For more complex waves such as the height of a water wave in a pond after a stone has been dropped in, more complex equations are needed.
