  2. Help:Displaying a formula - Wikipedia

    en.wikipedia.org/wiki/Help:Displaying_a_formula

    When an inline formula is long enough, it can be helpful to allow it to break across lines. Whether using LaTeX or templates, split the formula at each acceptable breakpoint into separate <math> tags or {} templates with any binary relations or operators and intermediate whitespace included at the trailing rather than leading end of a part.

    The default sans-serif may render certain characters indistinguishable, such as 1, I and l. In articles mixing raw wiki with <math> formulae, the appearance of the same variable in the two types of formula does not match (serif vs sans-serif). {} ('texhtml' class) Distinguishes a formula from the running text.

  5. Help:Advanced table formatting - Wikipedia

    en.wikipedia.org/wiki/Help:Advanced_table_formatting

    Solution: divide one of the tall cells so that the row gets one rowspan=1 cell (and don't mind the eventual loss of text-centering). Then kill the border between them. Don't forget to fill the cell with nothing ({}). This being the only solution that correctly preserves the cell height, matching that of the reference seven row table.

    Conceptually, an index is simply a mapping between a value and one or more locations. With a functional index, the value stored in the index is the output of the function specified when the index is created. This capability expands what is sargable beyond base column expressions. Sargable operators: =, >, <, >=, <=, BETWEEN, LIKE, IS [NOT] NULL, IN

  7. Mathematical markup language - Wikipedia

    en.wikipedia.org/wiki/Mathematical_markup_language

    A mathematical markup language is a computer notation for representing mathematical formulae, based on mathematical notation.Specialized markup languages are necessary because computers normally deal with linear text and more limited character sets (although increasing support for Unicode is obsoleting very simple uses).

  8. Help talk:Displaying a formula - Wikipedia

    en.wikipedia.org/wiki/Help_talk:Displaying_a_formula

    There is at least one OCR tool that can convert a handwritten formula to Latex and other formats. Mathpix allows 10 snips a month free. I don't know enough to edit the body of the Help page (I've not yet used Mathpix so don't know how good it is, and how compatible with Wikipedia, and don't know what else is out there), but I think there should be a Tools section with this sort of information.
