Have you noticed the option to add an image to a **Desmos graph**?

Editing a graph page recently I noticed you can add an image…

Clearly I had to experiment with this facility, so remembering the **beautiful dance moves poster** I thought I’d see how accurate it is!

The modulus function looks pretty good – as does the circle (though it really should not be labelled just x^{2}+y^{2})

Anyway – upload an image – save your page and challenge your students to fit a graph!

Remembering a **holiday in Barcelona** – I thought I would add the graph of cosh x to this photo.. Select the image to see the Desmos graph page.

An update – thank you **@Desmos** – love **this!**

Note the use of the drop down menu in each section.

And for a little more mathematical dancing – can you **dance the Bubble Sort?**
