More presentations in markdown with Beamer and Pandoc

This is another Pandoc / Beamer example presentation. This one includes:

• A syntax highlighted C code listing
• A slide with a two-column layout
• Background colour set to off-white (specifically 15% yellow)

Some useful links I came across while experimenting with this:

• https://hartwork.org/beamer-theme-matrix/
• https://gandrille.github.io/linux-notes/File_Formats/LaTeX/beamer/Beamer-appearance-cheat-sheet.pdf
• https://mpetroff.net/files/beamer-theme-matrix/
• https://github.com/alexeygumirov/pandoc-beamer-how-to
• https://www.andrewgoldstone.com/blog/2014/12/24/slides/ (explains about \setbeamercolor, xcolor mixing syntax)
• https://pandoc.org/MANUAL.html#producing-slide-shows-with-pandoc

This is the pandoc command to create the presentation PDF:

pandoc -t beamer test.md -o test.pdf

This is the full markdown file ("test.md"):

# Some slides are text-heavy

- This is quite a long and unwieldy sentence to have included in a bullet point in a presentation, especially since it adds little of value.

# Equations 

The roots, $r_1$ and $r_2$ of a quadratic equation $ax^2 + bx + c = 0$ can be found using the following formula.

$$r_{1,2} = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$$

# Another equation 

Here's another more complicated equation:

$$ \frac{x^n + y^n}{x^n - y^{\frac{1}{n}}} = \int_0^\pi z^n dz $$
