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!
Desmos & Images – select the image for graph page
Desmos circle – select the image for graph page
The modulus function looks pretty good – as does the circle (though it really should not be labelled just x2+y2)
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.
Dancing with Desmos- select image & dance!
And for a little more mathematical dancing – can you dance the Bubble Sort?
So – it’s the holidays – time for some updating and tidying up. With Easter approaching I thought I’d update the WolframAlpha slideshow with the non-chocolate variety of Easter Eggs!
…and a reminder of what a fantastic resource WolframAlpha is for checking work – see the recently updated series of WolframAlpha pages.
I have been busy putting together many of the very useful calculators and tools for checking work. These have previously been on a site of their own but I have now decided they are more appropriately placed on Mathematics for Students. I have also added a link (Calculators & Tools) on the right hand side here in the Links section. I have taken the opportunity to do some major updating and I will develop this further in the coming months.
I like to use tools like this in class to encourage students to use them independently for checking their work. I know this strategy works – one of my Year 13 students announced during a homework discussion earlier this year that she knew the answer in the text was wrong (it was) because she checked it on WolframAlpha! Happily I have had many similar comments.
