Mathematical Formula & LaTeX
WonderPen supports embedded mathematical formulas, if you are familiar with LaTeX or related syntax, it will be easy to insert all kinds of formulas in WonderPen.
Formula blocks
Formula blocks refer to formulas that occupy a single paragraph. They are usually wrapped between $$ and $$. E.g:
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$Will be rendered as:
If the formula is complex, you can also wrap lines in the middle, for example:
$$
\begin {aligned}
\sin \theta &= \sin(\frac{\pi}{4})(1 - 2\sin^2\alpha) - \cos(\frac{\pi}{4}) \cdot 2\sin \alpha \cos \alpha\\
&=\frac{1}{\sqrt{2}}(1 - 2\cdot(\frac{1}{\sqrt{5}})^2) - \frac{1}{\sqrt{2}} \cdot 2 \cdot \frac{1}{\sqrt{5}} \cdot \frac{2}{\sqrt{5}}\\
&= \frac{3}{5\sqrt{2}} - \frac{4}{5\sqrt{2}}
\end {aligned}
$$Will be rendered as:
Inline Formulas
You can also embed formulas within sentences within a paragraph. This form is called inline formulas. Inline formulas are usually wrapped between $ and $.
E.g:
This formula will be displayed in-line: $\left( \frac{n^2}{6} \right)$Will be rendered as:
Rendering Engine
WonderPen supports the following two rendering engines:
- KaTeX
- MathJax
You can choose your preferred rendering engine in Settings → Advanced → Additional. If you are not sure which engine to use, it is recommended to choose the default KaTeX.
