"Autograph  a new resource for all seasons"
An alldevice web version is due in the New Year. Meanwhile Autograph 5 will run all these files,
and it can be downloaded for free on www.completemaths.com, running on all Windows computers and preCatalina IOS
Any device will run all these videos.

1. A new feature of Autograph is the ability to define a new ‘XY’ point using attributes of other objects.
Here its coordinates are: the enlargement factor, ‘k’ and the enlarged area.
As ‘k’ is animated the values can be recorded and plotted to confirm a quadratic relationship (the host shape has area 6).

2. Single variable: points can be dropped in and moved about to help understand the box plot and its outliers.

3. VelocityTime graph entered as a piecewise function. The distance travelled is generated from the area to time ‘t’

4. Just 6 points added which can be moved about to help understand the mean, best fit line and correlation.

5. The very visible link between the sine graph and the unit circle, together with a locus of a chord of length 1.

6. Exploring an inequality: using the calculator to evaluate 2x–3y for a moveable point: more than 6 on the right!

7. A cone and a plane illustrating the conic sections, together with the construction of a parabola.

8. I have always wanted a 3D Argand Diagram and here it is!
Three views of the roots of
x² – 2x + c = 0
when ‘c’ = 2:
(a) in the xy plane ‘no solutions!’,
(b) in the 2D Argand diagram with ‘z’ entered as
1 ± √(1 – c)


In (c) in 3D with the ‘z’axis being imaginary.
Naturally this all comes to life as you vary ‘c’ dynamically.
