[BlindMath] Drawing trigonometric Functions and their Graphs

Fri Jul 20 18:27:36 UTC 2018

So is it mainly a graphing calculator?  I am just wondering if it does
derivatives and Integrals.

I can provide a little bit more information about Desmos.

The graphing calculator at https://www.desmos.com/calculator is designed to
work well with a screen reader (and so are the four function and scientific
calculators at https://www.desmos.com/fourfunction and
https://www.desmos.com/scientific).

The graphing calculator can also produce audio representations of graphs.
There's a short intro video about how that works at the top of our
accessibility documentation: https://www.desmos.com/accessibility

For turning in work, there are a couple of good options.

1. Share a link: every time you save a graph, we produce a unique url for
the saved work, so you could save a graph and then send someone a link to
the url that shows up in the url bar. That would allow them to see your work
online.
2. Use your browser's File > Print function to produce a visual printout 3.
Export an image from the share menu (CTRL + ALT + S on Windows, CTRL +
COMMAND + S on mac).

If you have access to a tactile graphics embosser, you could print the
exported image on that printer. I've been experimenting with printing to a
VP Max embosser this week, and I've found that printing an image exported as
"Size": "Medium Square", "Line Thickness": "Thin" works passably well.

We're interested in improving our ability to produce tactile graphics,
though. I think the biggest improvement will be allowing printing axis
numbers (and other lables) as Braille. There's also room to improve the dot
heights and line thicknesses for better legibility.

I would love to chat more with any teachers or students who are interested
in producing tactile cartesian graphs. Feel free to e-mail me directly (
jason at desmos.com) if you have ideas about this, or if you'd be interested in
testing improved Desmos tactile graphics.

Best,

Jason
