Regular readers will know I am a huge fan of the wonderful Desmos graphing calculator.
Take a look at the newly designed home page for some brilliant examples.
Click on any of the graphs to explore further and have a look at the equations used.
I have found this instructive for learning more about the syntax one can use.
I thought I would create a slideshow for my students showing the different types of graph which they should be familiar with at GCSE (taken at age 15-16 in the UK).
Each slide links to a Desmos page where they can use the sliders to explore families of curves.
