Graphical calculator vs Online

Inspired by this blogpost: The CASIO graphical calculator FX-9860G SD emulator, still in use is some classrooms in the Netherlands, on the left for y=sin(1/x), an online tool on the right. Both resized to a width of 263 px, ratios kept the same.

QED

(Of course TI would argue that you therefore need the TI-nspire CX full color with a whopping 320 by 240 pixels, and other features comparable to an old Nokia phone. But hey, that’s just me, it’s all about the pedagogy!)
