Math mode
All math mode input passes through pandoc without change and is left to be rendered by XeLaTeX or MathJAX.
- pay attention to braces, especially matching left and right ones
- whitespace is generally ignored in math mode, use it liberally to keep your equations readable.
All binary operators and
=signs should be surrounded by spaces. - if you do not know how to type a symbol, this might help
For fractions use $\frac{numerator}{denominator}$. Do not use dfrac unless absolutely necessary, except in Náboj answer.md.
Please restrict yourself to round braces. For correct sizing, use \left( a \right), except in simple functions like f(x).
$\left(x + y\right)^3 = x^3 + 3x^2y + 3xy^2 + y^3$
or the equivalent shorthand
$\lr{x+y}^3$.
Other paired delimiters are written similarly (\Abs, \Floor, \Ceil, ...).
Always keep block mathematics as blocks. The equation is a part of a sentence, and must use proper punctuation.
...so we now see that
$$
E = mc^2.
$$ {#eq:mc2}
Equations are typically numbered by their order within a problem. Use pandoc-crossref notation for cross-references.
...so we now see that
$$
E = mc^2.
$$ {#eq:mc2}
As we have shown in [-@eq:mc2], ...
will render as "As we have shown in equation 3.2.1, ...".
Keep your lines short at all times. Break at = signs or operators and move them to the next line.
So the total impulse is
$$
\FDiff{v_{\mathrm{II}}} =
\FDiff{v_{\mathrm{IIab}}} + \FDiff{v_{\mathrm{IIc}}} =
\left(
\sqrt{\frac{2\xi}{\xi + 1}} +
\sqrt{\frac{1}{\xi}} -
\sqrt{\frac{2}{\xi\left(\xi + 1\right)}}
\right) v_1.
$$
When you are showing a multitude of similar equations or simplifying an expression,
it often looks much better when aligned to the = sign. Use the & symbol for alignment,
along with \\ at the end of each of the lines (possibly except the last one).
$$
\begin{aligned}
c &= \left(a - b\right)^2, \\
c &= a^2 - 2ab + b^2. \\
\end{aligned}
$$
or an equivalent but non-standard extension of DeGeŠ,
$${
c &= \left(a - b\right)^2, \\
c &= a^2 - 2ab + b^2. \\
}$$
