2011年5月27日 · In my opinion, the annotation “= midpoint (in typography)” for the 00B7 · MIDDLE DOT symbol speaks for itself and I think one could use it in typesetting poems, for example, to mark stanzas or as a substitute for the regular space. From my point of view, the 2022 • BULLET should be used as a list symbol exclusively.

The vertical position is fixed to center the symbol vertically around the math axis as \cdot and \bullet do. The width of the symbol is not the scaled down width of the \bullet (with scaled down side bearings), but a little larger width of \cdot. The scale and width factor can be configured by macros \bigcdot@scalefactor and \bigcdot@widthfactor.

2021年3月18日 · As complement, as it's not exactly the fat dot you're looking for. From unicode: ⊙ (U+2299, cicled dot operator) ⨀ (U+2A00, n-ary circled dot operator) ☉ (U+2609, sun) From Latex: \odot usually for the unit solar mass

2020年2月10日 · We also use this same symbol for the dot product, although some books prefer the \circ. And we generally use \times for the cross product (vector product). Personally, I would never write 2(2)=4 or (2)(2)=4 in a text, even as a mathematician. I would …

2010年12月17日 · \textbullet (in text mode) and \cdot (in math mode) look pretty different; the former is much heavier. If you want a light dot, one option is just to write $\cdot$, of course. Alternatively, maybe look here or here. Interpunct on Wikipedia maybe also useful for tracking down the symbol you want. –

If I want to use the dot notation for the time derivative of a vector is better (more common) to put the dot over the vector, or the other way around \dot{\vec{v}} \vec{\dot{v}} The first says the rate of change of the vector components, and the second says a vector made from the component rates.

Personally I use the \times symbol only in three different occasions: (1) the cross product –vector product– (e.g., \vec j \times \vec k = \vec{\imath}); (2) to write dimensions (e.g., $3 \times 3$ matrix); (3) to write numbers in scientific notation –to visually know if the whole expression is a number or a multiplication– (e.g., 2.5 ...

That symbol when used in Chemistry (usually with the full bonds between atoms) denotes an extra free electron (it negative charge). The minus is actually saying it twice. These are usually used in Lewis Dot Structures (Diagrams) and mean a free electron (unbonded). Lewis Structure

Precedence rules usually help in deciding possible ambiguities: a function symbol ties more than operation ones, so. sin(x + 1)(a + b) should mean "the sine of x+1 multiplied by a+b", but it would be better to write the expression as (a + b) sin(x + 1) Note that a …

How may I augment or diminish the size of a symbol? 0 How do I globally adjust/stretch the in-between vertical spacing of items in lists only when they include display style fractions in inline math mode?
