Looking at the MEI AS/A Level Student Tasks for Autograph, Casio Desmos and GeoGebra, we see tasks for Numerical Methods which is part of the subject content for A Level Mathematics.
The MEI AS/A level Student tasks are excellent, they provide instructions for the use of the software and ask some great questions to get students thinking and exploring. Have a look at this Autograph task on Numerical Methods – Fixed Point Iteration. Autograph is brilliant for work on Iterative processes – the task shows how quick it is to use. You can zoom in on the image as you can see here. Remember that Autograph is now completely free. There is a wealth of information on how to use it available on TSM Resources.
