In 2015 I was writing lots of short recreational math documents. To aid myself in the creation of these, I built ArcType.
ArcType is a minimalistic editor that combines LaTeX, Markdown, HTML/CSS, gnuplot and Octave all in one place. A few months back I took ArcType and finalized it so that others could use it. It’s free and you can download your creations. Both the welcome screen and the helpfile cover most of the features available to you. Check it out here…
Here is a link to some of the docs I created…
It’s pretty self-explanatory - planning to do a tutorial about it soon. In the meantime, give this code a shot if you’re looking for more to play with than just the welcome/about demos.
# Modified Bicuspid Curve

Original equation from somewhere on [this page](https://en.wikipedia.org/wiki/Quartic_plane_curve)

(x^2 - a^2)(x - a)^2 + (y^2 - a^2)^2 = 0

[x,y] = meshgrid(lx, ly);
z = (x.^2 - a^2) .* (x - a).^2 + (y.^2 - a^2).^2;

the above will render this
There's only really one known issue on my radar - which is just the 5mb limit for localStorage... I'm sure there are other bugs - so if you decide to make something real with it - please save your work often ;)
If you have questions - feel free to post them here and I'll do my best to respond. If you make something cool with it - I'd love to see it.
Enjoy :D
