This is NOT a comprehensice review, but merely a little expression of delight about discovering handy applications for Desmos
. I must confess, whilst I know people have been talking and tweeting about desmos for a while, I just haven't made time to get around to looking at it. I still haven't had much time! For me I look for a few things in new stuff. First of all I want somebody to quickly outline potential!
Secondly I want to know what it can do that I couldn't do before and
Thirdly, how easily can I get started!
Well, I got instant delight from the 'instant slider' effect. Whilst it is certainly true that knowing how to tie sliders to constants in Geogebra is an inherent part of understanding both the maths and the software, there are times when the 'instant' slider is just what you want! This example is exactly what I used in class just the other day for exploring the impact of different variables on the shape of an exponential function. Almost no explanation required for students to be doing the same and making lots of great discoveries. I have a feeling that this maybe the first of many 'desmos delight' to come!
I was hoping to be able to embed an interactive graph i this blog post. I can see from some quick research that this is possible, but it didn't happen quick enough this time! That will be a delight saved for another time!
