How to use math inside of HTML code?

MathtoLatex 07 Aug 2019 14:06

Hi. I have a problem. I want to create a text area in my wikidot site, so it is possible by HTML code, but I need to use math equations inside of HTML code and it returns math equation without rendering. my code is something like this:

[[html]]
<textarea  style="resize:none" rows="10" cols="60" name="usrtxt" wrap="hard">
</textarea>
</form>
<p>[[$x^2+y^2=mc^3$]]</p>
[[/html]]

Output: [[ $ x^2+y^2=mc^3 $ ]]

(It works here oddly!!!!) What is the wrong? How to do this?

Testing: sum of squares

\begin{align} \sum_{k=1}^{n} k^{2} = \frac{1}{6}n(n+1)(2n+1) \end{align}

Wikidot syntax and modules won't work inside HTML blocks. If your equations can live outside the HTML block, you can do something like this.

The Code

[[html]]
<textarea  style="resize:none" rows="10" cols="60" name="usrtxt" wrap="hard">
</textarea>
</form>
[[/html]]
[[div style="width: 250px; text-align: left; /* other CSS as needed */"]]
[[math]]
\sum_{k=1}^{n} k^{2} = \frac{1}{6}n(n+1)(2n+1)
[[/math]]
[[/div]]

The Result

Note: HTML blocks are not rendered in forum posts

(1)

\begin{align} \sum_{k=1}^{n} k^{2} = \frac{1}{6}n(n+1)(2n+1) \end{align}
