Instead, it records the date and time that the page was most recently edited or purged. If you want a clock that constantly updates, then go to Special:Preferences#mw-prefsection-gadgets and enable the Appearance item, "Add a clock to the personal toolbar that displays the current time in UTC and provides a link to purge the current page".
An alternative to × is the dot operator ⋅ (also encoded < math > \cdot </ math > and reachable in the "Math and logic" drop-down list below the edit box or via template {}), which produces a symmetrically spaced centered dot: "a ⋅ b". Do not use the ASCII asterisk (*) as a multiplication sign outside of source code. It is not used for ...
In applied fields the word "tight" is often used with the same meaning. [2] smooth Smoothness is a concept which mathematics has endowed with many meanings, from simple differentiability to infinite differentiability to analyticity, and still others which are more complicated. Each such usage attempts to invoke the physically intuitive notion ...
{{Math templates | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{ Math templates | state = autocollapse }} will show the template autocollapsed, i.e. if there is another collapsible item on the page (a navbox, sidebar , or table with the collapsible attribute ), it is hidden apart from its title ...
In mathematical logic, it remains used for denoting implication, but its exact meaning depends on the specific theory that is studied. 4. Over a variable name , means that the variable represents a vector , in a context where ordinary variables represent scalars ; for example, v → {\displaystyle {\overrightarrow {v}}} .
The math template formats mathematical formulas generated using HTML or wiki markup. (It does not accept the AMS-LaTeX markup that <math> does.) The template uses the texhtml class by default for inline text style formulas, which aims to match the size of the serif font with the surrounding sans-serif font (see below).
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.
[[Category:Mathematics templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Mathematics templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character.
