Update – January 2013
I think they never sleep at Desmos – now look what they have done!
My favourite graphing calculator just keeps getting better and better!
The new version is available now, having used this a great deal over the last couple of weeks, performance has been superb, it’s fast, it’s slick – and it just works – every time! Note that you can download a very clear user guide.
I seem to keep writing about this excellent resource that I use all the time! I have therefore created a page where all the Desmos posts are together.
Experimenting further this week I created some pages to help students who are learning about solving trigonometric equations. I have used an Evernote shared notebook for these, you can just select ‘View Notebook’ to see the pages. Sharing pages is even easier now.
