Do Farmers use Desmos?

Last year I wrote about min and max tasks with real life examples.

This year I used the same ‘tray’ task again:
20131016 - AS Mech Max Min 1_1

But this time I used Desmos to collect their results:
5280c448d535cfa93400005e

And then to check our function seemed valid:
5280c47fd535cf6c4e000169

And then to see if our calculated maxima matched up with Desmos:
5280c4b0d535cf05d7000168
20131016 - AS Mech Max Min 1_3
Which it did, and that was awesome.

Sorcery just keeps making my lessons a little bit slicker and a little bit easier and a little bit more visual.
