Using mathematical and chemical formulas in Wooclap questions

Wooclap allows you to insert mathematical and chemical formulas in a question and its possible answers by using the AsciiMath and LaTeX formats. Know that it is possible to import into Wooclap a Moodle quizz including LaTeX equations. Conversely, importing into Moodle a Wooclap question including LaTeX content is also possible.

Note : These formats are not supported in the answers of Matching questions and for the categories of the Brainstorming questions. These answers/categories are displayed on students' phones as drop-down lists, the design of which we can't control. We are currently looking for a way to work around that limitation.

Guide to use mathematical and chemical formulas in your Wooclap's questions

AsciiMath

Simply surround formulas by backticks ` or by the elements <math> and </math>.

Examples:

<math>1/(x+1)</math>
or
`1/(x+1)`

<math>sum_(i=1)^n i^3=((n(n+1))/2)^2</math>
or
`sum_(i=1)^n i^3=((n(n+1))/2)^2`

You will find a summary of the available symbols here.

LaTeX

Examples:

$\frac{1}{x+1}$

$e^{i \pi} + 1 = 0$

$expires=1733248800&signature=29ab16e1c7c05267f5275e8e619ff2bcafaf3e76b73cae324ac07775c5ae8585&req=cicgEc1+lIgTWLcX3D+5hkaefsn7MRE7hNumOdiVhnRqKcqFC3Z+Q8opk9G+ xfi1dOSA+3AGG0MP$

$\oiint_{\partial \Omega} \mathbf{E}\cdot\mathrm{d}\mathbf{S} = \frac{1}{\varepsilon_0} \iiint_\Omega \rho \,\mathrm{d}V$

The formulas are rendered using the KaTeX engine. The list of supported functions is available here: https://katex.org/docs/supported.html.

N.B. If you wish to use the "dollar" sign in your question, here is how you can obtain it, without messing up your LaTeX format. You have to add a \ just before the "dollar":

 $$ 500 or \$ 500

Chemical formulas

Chemical equations can also be created in Wooclap thanks to the mhchem format. You just need to put a $ at the beginning and the end of the equation to make it appear in Wooclap. You will find more examples and information about the mhchem extension here.

Here are some examples:

Chemical formulae

$\ce{Sb2O3}$

Charges

$\ce{Y^99+}$

Nuclides/Isotopes

$\ce{^227_90Th+}$

Reaction arrows

$\ce{A <--> B}$

Parentheses and brackets

$\ce{[\{(X2)3\}2]^3+}$

Variables

$\ce{x Na(NH4)HPO4 ->[\Delta] (NaPO3)_x + x NH3 ^ + x H2O}$
