The title is pretty general but I have a bit of a specific question.
I'm given a database of TeX code. I'm not familiar with what sort of format it's in (LaTeX, KaTeX, etc.), I only understand that it is TeX form. Here are some examples:
Raw TeX:
Is there a number `a` such that `$\displaystyle \lim_{x \to -2} \frac{3x^2 + ax + a + 3}{x^2 + x - 2}$` exists? If so, find the value of `a` and the value of the limit.
The same question in HTML:
<p> Is there a number <code>a</code> such that <code class='latex inline'>\displaystyle \lim_{x \to -2} \frac{3x^2 + ax + a + 3}{x^2 + x - 2}</code> exists?
If so, find the value of <code>a</code> and the value of the limit.</p>
I want to display this on my web application, but I'm having difficulties finding which library I'm supposed to use to render these in. I don't know where the <code class='latex inline'> comes from. Can anybody identify what TeX form it is and how to render them?
